HyRAM™ is a composite layering system comprised of two (2) distinct applications.

1. The first application on the existing pavement, after preparatory work such as skin patching, crack sealing, and isolated dig-outs have been completed, is the Asphalt Rubber Aggregate Membrane, acronym ARAM, consisting of Asphalt Rubber binder, which is a combination of paving grade asphalt and crumb rubber derived from scrap tires, and is spray applied onto the pavement surface. Cover aggregate is applied to the Asphalt Rubber binder, and excess aggregate is swept off the surface, providing a crack-resistant and waterproof membrane.
2. The second application is a thin overlay (1 inch or less) over the ARAM. The overlay material is a HyRAP® hot mix asphalt, consisting of a fully sustainable paving material with its aggregate component comprised of 100 percent reclaimed asphalt pavement (RAP).
3. The finished HyRAM™ product, consisting of the (2) two applications described in paragraphs 1 and 2 above, provides the following benefits:

• • Streets slated for reconstruction with a solid sub-base can utilize HyRAM™ with cost savings of up to 50 percent

• • Proven performance both in freeze-thaw climatic conditions and heavy truck traffic loading applications
  • Less disruption to the public compared to other construction methods, allowing easy in and out traffic from residential neighborhoods during all phases of construction
  • Enhanced rideability compared to other preventative maintenance treatments
  • Sound Environmental Stewardship
    • Reduction of Greenhouse Gas Emissions (GHG)
    • Conservation of landfill space
    • Reduction in vehicle miles traveled (VMT) during construction operations
