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.

Rugged & Ready: MD3.0+ answers the call for plant integration

By | Asphalt | No Comments

MD3.0 Automated Dosing Machine for ACE FibersNow that asphalt producers have seen and used the new MD3.0 Automated Dosing Machine for ACE Fibers, the response has been overwhelmingly positive. In fact, many now want to integrate the MD3.0 into plant operations. We heard them, and we now offer the improved MD3.0+.

It’s more rugged, with upgraded welded and wiring connections, capable of withstanding tough, everyday use. And we now offer both pilot house control integration and a super sack feeder option for producers that want to integrate the MD3.0+ permanently into their plant operations.

ACE Fiber Mixing Process“From the comments we’ve received, it’s clear that plant integration is a big deal to asphalt producers. Integrating the MD3.0+ with both pilot house controls and a super sack feeder makes the system more automated at the plant, similar to how producers are used to producing asphalt,” says Joe Dennis, Vice President & Chief Technical Officer. “We have the technology to achieve the integration, for those who want it.”

The new and improved MD3.0+ will also prove to be more rugged for all producers, whether at the plant or transported to the job site.

“We’ve answered customer requests to make the MD3 sturdier, ensuring a longer life and greater dependability,” says Dennis. “The MD3.0+ is the new standard moving forward.”

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

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.

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.
