ACE XP® versus Paving Fabrics — you owe it to your next pavement to compare

By ACE XP No Comments

The advent of Surface Tech’s new ACE XP pavement overlay solution utilizes one of the strongest man-made fibers in existence — para aramid. ACE XP in a hot-mix, hot-laid overlay application can go head-to-head with typical fabric interlay applications in terms of cost. But in terms of performance, ACE XP comes out on top. It’s faster and easier to apply and more effective in reducing cracks.

A mix reinforced with ACE XP can be laid, worked, rolled and finished exactly the same as a regular mix with no special steps needed from the lay down crew. And as a bonus, ACE XP is fully recyclable. With paving fabrics, millings often go to the landfill. That makes ACE XP the sustainable choice for long-term pavement owners.

“We’ve had a lot of success with ACE XP in overlays, because once contractors use it, they love it,” said Michael Scardina, Regional Sales Director. “It’s a faster install, more crack resistant, and as a plant mix product, there’s no need for third party contractors so all the job profit stays in-house.”

ACE XP turns regular asphalt into a high-performance overlay, with the advantage of a faster and more consistent installation process. And since the overall cost of ACE XP competes well with the overall cost of installed paving fabrics, the only remaining question in your mind should be, “Why haven’t I tried it?”

Technical review of Indirect Tensile Strength testing advises caution in relying on results

Alternative tests, plus a balanced mix design, can improve predictions of asphalt performance

The indirect tensile strength (ITS) test has been utilized for more than 40 years as a definitive method for predicting the performance of asphalt mixtures. But the test, at 25°C, can render misleading results, according to a recently released technical brief by Phil Blankenship, P.E.

indirect tensile strength (ITS) test“While the indirect tensile strength test at 25°C is sensitive to changes in mixture properties such as air voids, asphalt binder content, binder grade, aggregate properties (angularity, texture, etc.), the resulting indirect tensile strength does not always equate to positive field results,” he writes. “In other words, high tensile strength alone does not always relate to improved cracking resistance.”

The author discusses various developments taken over the past 10 to 15 years in ITS testing to achieve more predictive results for top down cracking. However, differences in testing temperatures and loading rates may not, in reality, conform to ASTM D 6931 standards.

Blankenship presents data from various experiments that show a weak correlation between strength (at 25° C) and ALF cycles to failure. Various results of other tests also show that indirect tensile strength testing alone (at 25°C) can be misleading.

Instead, Blankenship advises that other cracking tests produce good correlations to field performance, and the types of tests and standards are provided within the paper. The author further explores taking a “balanced mix design” approach, or performance-based testing.

Discover Surface Tech at the TRB Annual Meeting at Booth #1133

By Asphalt, Concrete No Comments

Innovative products that deliver better, stronger, longer-lasting building materials 

Transportation Research Board (TRB) 98th Annual MeetingIt’s almost here! The Transportation Research Board (TRB) 98th Annual Meeting will convene next week in Washington, DC.  We’ll be there, and we invite everyone to drop by our booth to learn how Surface Tech products can deliver significant benefits to your next concrete or asphalt project.

Our innovative ACE XP polymer fiber solution can make asphalt stronger than steel. JUNO XP, our alternative supplementary cementitious material (ASCM), utilizes cutting-edge advancements in mineralogy and pozzolans to improve the performance of concrete at a microscopic level. Stop by and learn more.

You can also discover more about our products by attending Surface Tech’s TRB Live! Theater. Be sure to mark our presentations on your meeting calendar:

Monday, January 14th – 9:30 a.m.
What is an ASCM and why do we care?
Jon Belkowitz, PhD, Chief Technology Officer, Surface Tech
advanced supplementary cementitious materialPortland 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. Alternative supplementary cementitious materials 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. Surface Tech has been at the forefront of alternative binder technology since 2016. Come learn about JUNO XP. We are seeing spectacular potential for this product as an alternative supplementary cementitious material. We’ll explain how it can reduce cost and increase strength of traditional concrete in your next project.

The ideal asphalt cracking performance test — what is it?
Joe Dennis, Vice President & Chief Technical Officer, Surface Tech
Phil Blankenship, PE, BLANKENSHIP ASPHALT TECH AND TRAINING, PLLC
ACE XP Polymer FiberASCE recently gave U.S. roadways a dismal “grade D+.” One main reason for this poor performance is the premature cracking of asphalt pavements. This presentation will review a variety of cracking performance tests currently available, providing the strengths and weaknesses of each — including a review of the newest crack performance test called the IDEAL CT crack test. Since the availability of asphalt crack improving modifier options is limited, the presentation will also provide an overview of the capabilities of aramid polymer fibers to decrease this premature cracking of asphalt pavements.
