IDEAL-CT & Hamburg Wheel Tracker meet the need for crack/rut balanced performance testing in asphalt mixes

By | Asphalt | No Comments

ACE XP shows 30% to 50% improvements in both tests

 Indirect Tensile Cracking Test at Intermediate Temperature (IDEAL-CT)

Figure 1. Indirect Tensile Cracking Test at Intermediate Temperature (IDEAL-CT)

Asphalt pavements need to be stiff enough to minimize rutting, but resilient enough to bend without breaking to prevent cracking. The trend over the last 20 years has been one-sided — fixing the ruts at the expense of the cracks. Many in the industry have begun to recognize the need for a “balanced approach” to developing pavement designs that will perform well in resisting both rutting and cracking.

There are seven key existing performance or index tests for asphalt cracking (see Table 1). These tests vary in complexity and cost, and as a result, the asphalt industry has not traditionally performed cracking performance tests on every project.

Hamburg Wheel Tracker (HWT) Test

Figure 2. Hamburg Wheel Tracker (HWT) Test

For rut testing, the Hamburg Wheel Tracker (HWT) test tends to be the most widely used method. However, many agencies and specifiers, including DOTs, are moving toward adopting performance-based specifications where both mix designs and daily production will need to meet certain minimums in both cracking and rutting parameters in order to be considered.

A new and promising cracking test has recently been developed by Dr. Fujie Zhou and his colleagues at the Texas A&M Transportation Institute. The Indirect Tensile Cracking Test at Intermediate Temperature (IDEAL-CT) is a reduced cost method that provides consistent results to predict field performance in cracking. This test, along with HWT, can be used daily to ensure that asphalt mixes meet both rutting and cracking performance criteria in a balanced manner.

For example, tests utilizing the HWT and IDEAL-CT methods on ACE XP asphalt mixes can be seen in Figures 1 & 2. The results compare mixes with and without ACE XP and show clear performance advantages with ACE XP in both rutting and cracking sample results.

Bottom line: In balanced performance testing, ACE XP Polymer Fiber yields an improvement of 30% to 50% in both rutting and cracking performance. To learn more about ACE XP or how to achieve a balanced approach to testing using the IDEAL-CT method, contact us.

JUNO XP surpasses major milestone in Stage 4 testing toward achieving 1709 ASTM certification

By | Concrete | No Comments

JUNO XP - alternative supplemental cementious material

For years, contractors have utilized several common types of supplemental cementitious materials (SCM), including fly ash, slag cement, calcined clays, and silica fume to partially replace traditional Portland cement in concrete mixes. The use of these materials has been supported by significant research and testing, as well as long-term performance monitoring.

Now the same rigorous testing procedures are being applied to JUNO XP, Surface Tech’s alternative supplemental cementious material (ASCM), and the reports from Stage 4 testing show JUNO XP produced “fantastic results,” according to Jon Belkowitz, PhD, chief technology officer for cement.

“The 90-day strength test results show JUNO XP is awesome! Throughout the 90-day set of results, the strength and durability of the JUNO XP-enhanced concrete proved out above the 1709 ASTM references.”

The innovative technology behind JUNO XP generates a hardened matrix that increases cementitious efficiency (see Compress Strength graph), and the resistance to physical attack (see Underwater abrasion graph).

Testing on JUNO XP covers a one-year time period, and by achieving excellent results at the 90-day milestone, the product will now enter the field-testing phase.

Standards for the evaluation of materials for 1709 ASTM certification can be found at https://www.astm.org/Standards/C1709.htm

Colorado Ready Mixed Concrete Provider finds JUNO XP weathers Rocky Mountain climate

By | Case Study - Concrete, Concrete | No Comments

JUNO XP alternative supplemental cementitious material (ASCM)For challenging winter weather, look no further than Colorado. During the cold months, concrete pavement must withstand an unending cycle of freeze-thaw and a constant barrage of de-icing salts. When a Colorado-based concrete provider  sought a new solution to this age-old problem, they turned to Surface Tech.

JUNO XP ConcreteWith fly ash in short supply, the concrete provider needed an alternative supplemental cementitious material (ASCM) that would meet ASTM C 672 specifications for a high-end residential driveway. The specs called for a high compressive strength and an ASCM that would ensure a dense hydrated concrete matrix. It was an ideal test for JUNO XP, Surface Tech’s pioneering ASCM product.

Using Surface Tech’s Rapid Deployment technology, JUNO XP was easily added to the mix with no issues or delays in the standard process. Concrete finishers remarked on the ease of finishing despite the reduction in paste content. The mix also retained fresh properties, compressive strength and resiliency when tested from samples fabricated during laboratory and field trials. Best of all, the test delivered significant cost savings without sacrificing fresh or hardened properties. Moreover, a third party testing laboratory confirmed that the JUNO XP concrete maintained the strength and shrinkage required by the engineering specifications.

The concrete provider in Colorado — and others like it across North America — have consistently found that JUNO XP-enhanced concrete will maintain performance, lead to cost savings and create an environment for a greener concrete mix design.

ACE XP aramid polymer fiber additiveAll require strength, flexibility and abrasion tolerance to achieve high performance. The common ingredient that delivers those winning traits is aramid fibers. These polymer synthetic fibers provide advantages that make them ideal for a wide range of products. So it’s not surprising that more than 60,000 tons of aramid fibers are produced annually, and demand continues to grow as new applications emerge.

Years ago, Surface Tech recognized the superior advantages that aramid fibers, particularly para-aramid fibers, could provide to asphalt applications. The company began offering the ACE XP aramid polymer fiber additive after years of painstaking research and multi-geographical testing. Back then, the challenge was to find a way to harness millions of tiny fibers into a final product that could be easily managed. By combining para-aramid with a wax treatment, Surface Tech achieved its goal of creating an additive that successfully reinforces and properly doses the entire matrix of asphalt.

The wax binds the polymer fibers to allow for an easy, reliable method for feeding into the asphalt mix. Once added, the wax melts and is fully soluble within the mix to release the polymer fibers in a uniform distribution. This unique delivery process produces the highest performing blend of Fiber Reinforced Asphalt Concrete (FRAC) on the market, and any asphalt project can benefit from ACE XP.

If you want an asphalt surface that resists cracking and rutting and dramatically extends the life of your pavement, call us. With para-aramid fibers, you’ll get asphalt that’s stronger than steel, and only from ACE XP — the Number One choice for strength, flexibility and abrasion tolerance.

Turn to ACE XP for Extreme Performance Asphalt

By | Asphalt | No Comments

ACE XP Polymer Fiber for asphalt

Contractors have come to depend on ACE XP Polymer Fiber from Surface Tech to make asphalt more durable and long-lasting. How does this high-tech additive deliver on its promise to produce extreme performance asphalt? The key lies in its chemical makeup — it’s composed of aramid polymers.

Aramid polymers contain a set of chemical properties that give them outstanding strength, flexibility and abrasion tolerance. They’re particularly useful in applications where flexing tolerance is important, like armor, airplane wings, ropes, cables, undersea pipelines, and of course asphalt applications.

To create ACE XP, high-strength aramid fibers are bundled and coated with wax to produce an asphalt additive that is simple and dependable to mix with any WMA or HMA in both drum and batch operations.  In fact, this binder use insures proper aramid delivery into the WMA/HMA; and coupled with our precise dosing equipment, delivers consistently intended amounts into every ton of asphalt.

One of the most outstanding performance benefits of ACE XP lies in its micro roots. These tendrils tenaciously anchor themselves into the bitumen of the asphalt, providing 400,000 psi tensile strength. The result is a three-dimensional reinforcement throughout the asphalt and a flexibility that resists rutting during hot summers and cracking through cold winters.

Contractors will also appreciate the fact that ACE XP is a “dry” polymer fiber. Comparatively, it’s less expensive, more reliable, and easier to adopt. The MD3+ dosing system from Surface Tech delivers an easy, foolproof way to add ACE XP to any asphalt mixture.

Yet the ultimate beauty to ACE XP is its scalability and batch-to-batch reliability. Combined with the life-span improvements it provides, it’s a winning way to armor your asphalt for the long haul. That kind of reliability allows contractors to sell and place with confidence, knowing the asphalt they provide will deliver extreme performance based on an excellent polymer.

ACE continues to go academic

By | Asphalt | No Comments

UC Berkeley and University of Alberta put it to the test

ACE XP Polymer FiberSurface Tech’s ACE XP Polymer Fiber (advanced performance product) is currently undergoing rigorous testing by researchers at two stellar universities. The quest:  Fully understand and document the benefits and material advantages of adding ACE XP Polymer Fibers to asphalt mixtures.

Principle investigators (PI’s) at the University of California at Berkeley including Dr. Angel Mateos in the university’s Pavement Research Center (UCPRC), are testing ACE for strength, fatigue and modulus in compliance with CALME standards; all in conjunction with Teichert Materials, ST’s NoCal distribution partner.  UCPRC is using the new Ideal CT test as part of their regiment.

“There has been an explosion of interest in the ACE XP Polymer Fiber product within our industry,” says Phil Blankenship, P.E., a strategic advisor to Surface Tech. “Major universities are taking notice. This type of high-level performance testing will help producers everywhere better understand ACE XP and how it can improve their asphalt mixes.”

When word of ACE XP Polymer Fiber reached the University of Alberta in Canada, Luis Perca (graduate student) and Leila Hashemian (Asst Professor), a faculty member in the Chemical & Materials Engineering Department, contacted Surface Tech to request assistance in analyzing the product. PI’s there are now testing ACE XP with a specific focus on performance in the tough Canadian climate, while also analyzing how the individual fibers contribute to asphalt strength, workability and long life.

“We expect results from the testing and analysis conducted by these universities will be available in six to nine months, and we’re pleased to see the continued interest among academics in our product,” says Blankenship.

Juno Concrete

How does Juno XP Impact the Glue of Concrete?

By | Concrete | No Comments

Juno ConcreteWhat is the glue of concrete?

Concrete is a mixture of aggregate, Portland cement, and water. But what actually holds concrete together? The answer is the hydrated cement matrix – the glue of concrete. Concrete is formed when Portland cement materials are combined with water to create a paste that binds with sand and rock to harden and form a composite structure. Common materials used to manufacture cement include limestone, shells, and chalk or marl combined with shale, clay, slate, blast furnace slag, silica sand, and iron ore. These ingredients, when heated at high temperatures, form a rock-like substance that is ground into the fine powder we call cement.

The hardened cement matrix of the concrete composite is a porous and hardened sponge that provides the structural strength for civil construction as well as the backbone for durability and a long service-life.

The ultimate object of combining Portland cement with supplementary cementitious material is to increase the efficiency of the cementitious matrix, maintain and enhance the fresh and hardened properties.

Why do we care?

Concrete is one of the oldest and most reliable construction materials in the world. Concrete is at the foundation of our civilizations providing everything from the sidewalks in urban, suburban, and rural areas; to the enormous concrete dams, like the Hoover Dam, spillways, and locks.

In order to achieve the durability of concrete, large amounts of Portland cement are utilized. Although cement provides concrete binding, cement production accounts for 3-5% of the worlds CO2 emission.

Cement is manufactured through a closely controlled chemical combination of calcium, silicon, aluminum, iron and other ingredients. The manufacturing of cement is a long process and at every stage of its production, the environment is affected. Carbon emissions, water pollution, and release of heavy metals in the air are common problems associated with manufacturing.

Cement dust is a pollutant that affects both the health of people and plants. Chronic diseases and respiratory disorders are observed in people who work in a cement industry and are exposed to the cement constituents and cement dust. The setting of cement is a long process and it is alkaline in nature, which may lead to lung and skin disorders because of the excessive heat normally released during setting and curing (Cement Production, Hazards, and Recycling, 2011).

How does Juno XP affect the glue of concrete?

The proprietary and novel make-up of Juno XP effectively manipulates the molecular kinetics of cement hydration to increase the toughness and durability of concrete; making concrete stronger and last longer. The science behind Juno XP is a combination of pozzolanic and mineral materials that increase production of the strength-bearing microstructure. Juno XP also has a mechanical impact on fresh concrete and creates an environment that allows for a reduction of traditional cementitious material while maintaining the creaminess needed to allow grey concrete to go down the chute into the formwork.

Juno XP acts as a binder replacement to allows for a reduced the need for cement. Juno XP allows for the following:

  • Maintenance of fresh properties
  • Increase in Strength and Toughness of Hardened Concrete
  • Environment for Portland Cement reduction is created

Juno XP creates performance based concrete that delivers the same properties of traditional concrete with a reduction in both cost and environmental impacts. Juno XP, saving the world with all the concrete in it.

Faster. Less Expensive. Easier. Reliable. The IDEAL crack test of the future — here now.

By | Asphalt | No Comments

IDEAL crack test asphaltAsphalt cracking tests provide critical information on the viability of asphalt mixes, but a critical need exists for a more practical cracking test for routine use. To meet this challenge, researchers Fujie Zhou, Soohyok Im, and Lijun Sun at Tongji University in Shanghai, China, and Tom Scullion at the Texas A&M Transportation Institute, developed the indirect tensile asphalt cracking test (IDEAL-CT), a method that we predict will achieve widespread adoption.

“The IDEAL-CT provides clarity on what is going on with samples,” says Joe Dennis, Surface Tech Vice President/CTO for Asphalt. “Since cracking is now the primary reason for asphalt remediation, we view the IDEAL-CT as a major advancement in ensuring that asphalt pavement meets standards that minimize cracking and result in a longer life. The test’s reliability and low cost, as well as the time-savings it delivers, has the potential to revolutionize asphalt testing industrywide.”

The test can run at room temperature and requires no instrumentation, cutting, gluing, drilling or notching of specimens, nor in-depth training for testing personnel. Best of all, it produces results in less than one minute.

Moreover, the IDEAL-CT can be performed with ordinary indirect tensile strength test equipment, and it’s sensitive to key asphalt mix components and volumetric properties, including reclaimed asphalt pavement, recycled asphalt shingles, asphalt binder type, binder content, aging conditions and air voids. In other words, IDEAL-CT is a practical solution for testing routine uses in the process of mix design, quality control (QC) and quality assurance (QA).

IDEAL-CT is gaining traction already. It’s currently working its way through ASTM  committee ballot shepherded by ASTM 04.26 sub committee and Phil Blankenship, P.E.  Surface Tech has embarked on several test cases utilizing ACE Fiber mixes. A test case in Texas has recently yielded reliable results. Further testing with and without ACE Fiber will occur in concert with the Kentucky Transportation Cabinet (KYTC) in October.

Why are alternative supplementary cementitious materials important to the construction industry?

By | Concrete | No Comments

alternative supplementary cementitious materialsThe invention of Portland cement 175 years ago heralded a new era in construction worldwide, and today it is the most widely used building material. Architects and general contractors appreciate its versatility, durability and economic value, and for its sourcing of local materials in production. That’s the good news about Portland cement.

The bad news:  Portland cement consumes vast quantities of energy and releases CO2 in the process. And since it’s produced in such gargantuan quantities, the construction industry faces increasing pressure to find alternative supplementary cementitious materials to replace Portland cement in concrete.

Portland cement concrete already incorporates a wide range of supplementary cementitious materials, including fly ash from coal combustion, and silica. However, these materials do not address all of the shortcomings of Portland cement in certain applications and environments. For instance, Portland cement concrete can degrade rapidly in environments with high acidity or high sulfate concentrations.

In addition to replacing Portland cement, alternative supplementary cementitious materials also hold the promise of increasing the strength of concrete, requiring less water in the mix, improving workability and producing a concrete that’s less brittle. So naturally, the search for alternative supplementary cementitious materials to replace Portland cement has picked up speed over the past decade.

Surface Tech has been at the forefront of alternative binder technology since 2016. As Juno enters its final phases of testing and refinement, we are seeing spectacular potential for this product as an alternative supplementary cementitious material that will easily conform to ASTM standards and mitigate many of the problems inherent with traditional alternative supplementary cementitious materials.

Beat the fly ash shortage with JUNO XP!

By | Concrete | No Comments

Beat the fly ash shortage with JUNOConcrete producers often rely on ASTM C 618 Class F fly ash, derived from burning coal in power plants, as a partial substitute for Portland cement. Yet despite loosening regulations, the coal industry continues to suffer from America’s dwindling appetite for coal, and the unintended consequence is a shortage of coal combustion residue and fly ash. Many concrete producers now report having to use straight cement mixes, which increases cost.

Globally, significant sources of Class C fly ash exist, but the lower quality makes this product difficult to activate, and transportation adds to the cost. Class C fly ash is not as effective in mitigating chemical attack as Class F fly ash. However, there is one sure way to beat the shortage of high-quality fly ash:  Switch to Juno.

Juno XP is an advanced mineral admixture developed by Surface Tech that can replace fly ash as a partial substitute for traditional cement. It can be used in standard concretes, as well as in specialty applications without sacrificing performance.

The core technology found in Surface Tech’s Juno XP is a revolutionary building material using cutting-edge advancements in mineralogy combined with a graduated fiber matrix to reduce material cost. In fact, concretes that incorporate Juno as a binder often have higher performance characteristics than traditional concretes.

For more information on how Juno XP can lower cost and improve performance in projects like soil stabilization, controlled density fill (CDF) and rip-rap, visit http://surface-tech.com/portfolio/juno/.

JUNO passes initial laboratory testing with flying colors

By | Concrete | No Comments

Juno ConcreteThe results are in, and JUNO has proven it can increase strength and durability as well as decrease shrinkage in the laboratory tests that have been conducted to date. Surface Tech CTO Jon Belkowitz reports the product performs well in all areas that have been evaluated.  He sees JUNO as an easily-adoptable means to improve most types of concrete mix designs. The evaluation of JUNO will continue as it completes ASTM C1709 certification.

“Overall improved performance characteristics are some of the value propositions Juno is creating”, says Dr. Belkowitz, who also serves as the Director of Research and Development at Intelligent Concrete, a materials laboratory that specializes in concrete research, development and education with a focus on innovation.

It’s the fine particle size, in particular, that plays an important role in the material properties of JUNO. The core technology found in JUNO employs a revolutionary building material that utilizes cutting-edge advancements in mineralogy, combined with a graduated matrix.

The result is an alternative supplementary cementitious material that can reduce the amount of traditional cement and fly ash needed in concrete, while increasing fresh and hardened properties, thus saving money on cement/fly ash in the concrete mix. And Juno reduces CO2 emissions resulting from cement usage.

Better yet, and in concert with the performance characteristic improvements, JUNO produces a concrete that maintains fresh properties and improves strength in the final product, which adds up to a longer life for the concrete.

“We’ve run a number of tests for different applications, and JUNO is proving to be a phenomenal product,” says Dr. Belkowitz.

New and improved! MD3 now designed for specific sizes of ACE Fiber

By | Asphalt | No Comments

MD3 mixing ACE FibersThe latest version of Surface Tech’s Micro Doser system, the MD3, takes the process of mixing ACE Fibers into produced asphalt to a new level. Most notably, an improved onboard computer interface now allows operators to specify either 19mm or 38mm sizes of ACE Fiber to feed through the system. While the MD3 still allows for either bulk or sprinkle feeding, the new size-specific setting yields more exacting data and further improves the system’s efficient and thorough distribution of fibers.

An added feeder tray and improvements in controlled vibration ensure steady material flow and dosing accuracy, both critical to ensuring the long-term performance of ACE Fiber reinforced asphalt.

The MD3 can also be retrofitted to connect directly into existing asphalt plant controls to allow producers to permanently add the MD3 to the plant’s operational capabilities.

MD3 Micro Doser systemWith all the improvements, operators will find the system more user friendly than ever. However, some features needed no improvement. The system can still fit in a cargo trailer, can be set up in minutes, and can still be operated by one person. Moreover, producers can be easily trained and certified to operate the MD3 system if they opt to manage the QA/QC themselves.

Like its predecessor, the MD3 only requires 90psi and 185 CFM of compressed air and 110 volts electric to run, which means it can be easily included in the asphalt mixing process at both batch and drum plant facilities.

The computer interface still tracks cycle weight and time to ensure the accurate dosing of 4.2 ounces of ACE Fiber into each ton of produced asphalt. Data continues to be kept onboard and can be retrieved by USB, or sent via internet if available.

The MD3 continues the excellent tradition of the MD2 — delivering a perfect mix, every time! See video of MD3 in action at http://surface-tech.com/portfolio/ace-fiber-mixing-process/

Surface Tech’s ACE Fiber used in Sustainable Innovation for Parking Lots

By | Asphalt | No Comments

Ohio parking lot using ACE Fiber is one of six in the world designated as a demonstrator site for best practices in sustainable design and operation.

The Parksmart program through Green Business Certification Inc. (GBCI) recently recognized a new green surface parking lot at The Mason Business Center (MBC) in Cincinnati as a demonstrator site for sustainable design and operation. The MBC lot, which incorporated Surface Tech’s ACE Fiber into the asphalt, is one of only six in the world to achieve the Parksmart program designation.

The U.S. has an estimated 500 million surface parking spaces which cover more than one third of some cities’ land mass. Parking lots can add to water pollution through runoff, raise urban temperatures, and contribute litter to the landscape. Parksmart and other forward-thinking companies like Surface Tech are exploring ways to reimagine paving materials to be environmentally-friendly, socially responsible, and long-lasting.

“When designed with sustainability in mind, surface parking can help reduce energy consumption, improve air and water quality, and safely connect neighborhoods and people,” said Paul Wessel, director of market transformation and development for Parksmart.

Atlas 10 chose ACE Fiber to achieve optimum performance and extended lifespan benefits

Atlas10, a Pendleton-based pavement management company, managed The Mason Business Center (MBC) parking lot project and procured resources, including Surface Tech’s innovative asphalt additive, ACE Fiber. These high performance engineered fibers were chosen for their ability to produce a stronger pavement, which extends its lifespan and saves money by reducing the need for frequent repairs and replacement. ACE Fiber additive produces a surface of higher strength and superior resistance against cracking and rutting delaying costly maintenance and reducing the CO2 footprint of the pavement over it design life.

“Sustainable surface parking benefits the community, environment and property owners,” said Mark Schmidt, CEO of Atlas10 during his interview with BizJournals.com. “It’s an honor to work with The Mason Business Center (MBC)  and the other construction partners to make sustainable parking a reality, and we are pleased that the project we orchestrated is now a demonstrator site.”

The Cincinnati parking project was recognized by Parksmart during a presentation at Mason campus on February 2, 2018, which included facility manager, Atlas 10 and partners SurfaceTech, and 10 Mile Creek.
