Asphalt Interlayers

Asphalt Interlayer Systems extend the life of new AC pavements and AC overlays. When placed between layers of AC pavement, these systems become an integral part of the roadway section, forming a barrier to water infiltration and absorbing stresses to reduce reflective and fatigue cracking of the new asphalt surface layer.


The GlasGrid® Asphalt Reinforcement System is essentially a grid structure of fiberglass strands coated with an elastomeric polymer that has an exceptionally high tensile strength and elasticity. It successfully dissipates vertical crack stresses of a roadway by turning them horizontally when it is laid between the leveling course and the surface course in an asphalt overlay.

The GlasPave® mat’s geosynthetic, non-woven, polyester matrix facilitates the binding of asphalt to completely penetrate and fill the voids in the matrix. This design promotes an immediate, durable bond with a variety of asphaltic task coats. Its waterproofing abilities inhibit the infiltration of surface moisture into the granular layers of a pavement structure and is well-suited to lower volume pavement surfaces.

ACE XP Polymer Fiber

This is an innovative fiber that extends pavement service life by dramatically improving the dynamic modulus of the asphalt layer and increasing the asphalt’s resistance to cracking and rutting (distresses that may cause premature failure).

Aramid Fibers are used extensively in many industries and applications including ballistic protection, heat & cut protection, automotive, ropes & cables, conveyor belts, etc. However, it takes a special fiber to withstand the extreme production temperatures of asphalt concrete without changes occurring to the reinforcement properties of the fiber. That is why ACE XP Polymer Fiber™ uses aramid fibers exclusively.

Reinforced Joint Membrane

Applied as highway underlayments over cracks or joints on the old pavement prior to a new overlay, Reinforced Joint Membranes have been proven to:

  • Provide a permanent seal, even if the new pavement above the underseal cracks
  • Reduce the amount and severity of cracking in the new pavement surface, thus reducing pavement maintenance
  • Provide an impermeable barrier protecting steel rebar from moisture and corrosion when applied to bridge decks or parking garages prior to overlay

Tack Coats

A tack coat is a thin bituminous liquid asphalt, emulsion or cutback layer applied between HMA pavement lifts to promote bonding. Adequate bonding between construction lifts and especially between the existing road surface and an overlay is critical in order for the completed pavement structure to behave as a single unit and provide adequate strength.

American Road Patch

American Road Patch is a high quality asphalt polymer and fiberglass geosynthetic reinforced patch. It was developed using a unique patented technology and works by embedding into the roadway forming a waterproof seal around the repair.

Today’s current road repair methods do not address the cause of the problem – keeping water out. Traditional repair methods use only fills, which are temporary at best. American Road Patch is the solution!
