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?”

ACE XP Polymer Fiber helps a new pavement design achieve a higher standard in crack prevention

A custom asphalt mix design utilizing ACE XP polymer fibers has given a general aviation airport the long-term solution it sought for a nagging pavement cracking problem. Initial results show the custom design, which combined both a binder layer and a surface layer reinforced with ACE XP, will exceed expectations by greatly reducing cracking potential.

The six-year-old runway pavement at Taylor County Airport in Kentucky was failing. Airport authorities called on Palmer Engineering to provide a desperately needed 15-year-plus solution to the pavement’s micro-cracking problem. Working with Haydon Materials, the team turned to an expert with long-standing experience in designing crack-resistant asphalt pavements.

“The airport authorities were concerned that numerous cracks in the existing pavement could lead to failure, a common failure in airport pavements as aging occurs can create FOD — Flying Object Debris — causing a danger to the aircraft and potentially the traveling public.”

No milling was done on the runway pavement prior to re-paving. This meant the existing cracks would be exposed to the bottom of the  binder layer and would ultimately  reflect upward through the new pavement. The solution called for an inordinately crack resistant and resilient binder layer that either needed to be custom-designed, or an expensive two-dimensional geosynthetic rolled interlayer product.

“As a member of Surface-Tech’s Technical Advisory Committee, Phil is well versed on the capabilities of ACE XP, and he set about designing a completely new binder layer asphalt mix using it.”

Blankenship was able to deliver a design that Haydon could produce in its plant and pave with existing paving equipment. Using ACE XP in the new binder layer design gave Haydon Materials an effective crack resistant solution, while maintaining cost control for this demanding application.

The customized ACE XP mix achieved a new level of flexibility for the binder layer. The new binder layer design — a finely graded, highly asphalted crack resistant mixture — greatly reduced the potential for cracks to reflect upward from the base through the new pavement.

An  ACE XP reinforced surface mix was also designed utilizing a higher-than-normal asphalt content to provide even greater crack resistance than a typical FAA asphalt mix design,

“The development of this unique combination of mix designs for the binder and surface layer is an exciting advancement for the paving industry that holds great promise for dramatically improving crack prevention,” said Dennis.

“With this new approach, contractors can also control the quality in both production and installation, as the new mix design is simply incorporated into the contractor’s production processes, thus eliminating third party contractors to install the 2-dimentional geosynthetic rolled interlayer product.”

CASE STUDY: Louisville Adds ACE XP to Overlay to Extend the Life of a City Street

By ACE XP, Asphalt, Case Studies No Comments

ACE Fiber to Overlay to Extend the Life of a City StreetWhen the City of Louisville in Kentucky wanted to extend the life and delay the maintenance cycle of a resurfacing project on West Broadway downtown, they protected their investment by adding ACE XP to the mix.

Current and historic research and case studies show that ACE XP significantly enhances asphalt concrete performance. A 140% increase in crack resistance and 60% rut resistance have been demonstrated.

“By adding ACE XP to the 1.5-inch overlay, Louisville Metro can expect it to last longer and need maintenance less often. Like all of our clients, they want to save time and money that they devote to roads,” said Jeff McConahy, regional account manager for Site Supply, the ACE XP distributor in Kentucky and Ohio.

Adding ACE FiberMcConahy worked on the project with the paving contractor Flynn Brothers Contracting and CBC Engineering, whose technicians added the fibers to the asphalt.

Louisville Metro will continue to monitor the improved performance of the road. Producing and installing the ACE XP Polymer Fiber reinforced asphalt went very well with no issues or changes to typical procedures.

“Mixing at Flynn Brother’s plant and paving with the fibers on West Broadway was a great experience for everyone,” said McConahy.
