Introducing the “Ambient Mix Asphalt” Process

Posted .

EnviRoad LLC is proud to present our latest technology known as “Ambient Mix Asphalt”. Ambient Mix Asphalt (AMA) is an emerging green technology comprising of several cold-mix processes. All of the AMA processes utilize Earthbind® products. Presently, the AMA technology includes Stabilized Full Depth Reclamation, Ex Situ Aggregate Base Stabilization, Cold In-Place Recycling, and the Alternative Paving process. Following is a short overview of each of the AMA processes. These include:

  • Stabilized Full Depth Reclamation (SFDR)
    • Stabilized Full Depth Reclamation is a rehabilitation method in which the full thickness of the asphalt pavement and a portion of underlying materials (base and/or subbase) is pulverized and blended with a predetermined amount of Earthbind® solution, to provide an upgraded, stabilized homogeneous material. The SFDR method is for stabilization and is not considered to be paving. 
  • Ex Situ Aggregate Base Stabilization Process (EABS)
    • The Ex Situ Aggregate Base Stabilization is the process when excavated or raw material is thoroughly mixed with a predetermined amount of Earthbind® solution in a Pugmill. Then the blended material is then transported to the site in trucks and constructed into a new base using a paving machine. This process is typically done relatively close to the project location. The EABS methods is a base stabilization method and not considered paving. 
  • Cold In-Place Recycling (CIR)
    • Cold In-place recycling is a rehabilitation technique in which the existing pavement materials are recycled and reused in place…for the construction of a restored pavement layer. The CIR method allows for materials to be mixed in-place without the application of heat. The Ambient Mix Asphalt CIR method usually involves milling the top few inches (usually 3 to 5 inches) of the paved surface, mixing the pulverized RAP with a pre-determined amount of Earthbind® EBS-RA, and placing it back down with a paver. The AMA CIR method uses 100% of RAP generated and does not incorporate any of the underlying base or subbase. The AMA CIR can be considered to be a paving method.
  • Alternative Paving (EBAP)
    • Earthbind® Alternative Paving is a method in which either RAP and/or aggregate, is thoroughly mixed with a pre-determined amount of Earthbind EBS-RA solution in a Pugmill. The blended material is then transported to the site in trucks and constructed into a new paving layer using a paving machine. The EBAP method is an ex-situ method and is not done “in-place”. The EBAP method is a paving method and not considered to be a stabilization method.

This blog is simply a brief introduction of the Ambient Mix Process. This information will be followed up with additional blogs that will go into greater detail regarding each of the four AMA technologies.
