A waterproof barrier to prevent fines infiltration into the subgrade and pavement structure.

In addition to site paving benefits, ACB can be advantageous because it can provide: For more information on how Earthbind® Stabilizer can work for your project, please contact an EnviRoad sales engineer at 50.Asphalt concrete base (ACB), also called asphalt treated base (ATB), is a dense-graded HMA with a larger nominal maximum aggregate size (1 inch) intended for use as a base course or binder course (see Figure 1). The benefits of using the AMA process with Earthbind® Stabilizer will definitely help maximize the long-term performance of your road.

Improved moisture resistance and durability.

Acquiring flexural strength due to the visco-elastic properties of Earthbind®.

Can reduce pavement thickness requirements on road bases that will be paved.

Provides temporary or permanent (with maintenance) wearing surfaces on unpaved low-volume roads.

Helps minimize potholes (in combination with adequate drainage).Greatly reduces maintenance activities and maintenance costs.Upgrades marginal material that are typically undesirable for the sub-grade or for road base construction.Decreases the “erosivity” of the road material.Reduces dusting and conserves fines and aggregate material.Adds water-resistance/waterproofs the treated material.Improves the strength and durability of the soils/aggregate.The benefits of stabilization of sub-grade, sub-base, and road base with Earthbind® Stabilizer include: Earthbind® Stabilizer is specifically engineered to be an effect, environmentally friendly soil stabilizer. The AMA methods for native soil/aggregates is a base stabilization method and not considered paving.ĮnviRoad’s Earthbind® Stabilizer product is used in the ambient mix process. This AMA mixing process is typically done in close geographical proximity to the project location…close enough where the Earthbind treated material remains fresh. The AMA blended material from the pugmill is then transported to the project site and constructed into a new base using a paving machine. a milling machine or motorgrader is that the material is more thoroughly mixed and coated therefore increasing the efficacy of the particle to product contact and bonding. The AMA process instead is an ex-situ construction process where excavated existing or virgin road material is thoroughly mixed in a pugmill with a pre-determined amount of Earthbind® solution. Normally, chemical base stabilization processes entail mixing a stabilizer into a base material, in-place, using a motorgrader or milling machine. When such conditions exist, it can be important to stabilize the sub-grade, sub-base, and or the road base. Consequently, natural in situ soils may not provide the support that is needed to achieve acceptable performance under traffic loading and environmental conditions. It is well known that the performance of a paved and unpaved road is significantly impacted by the stability of the base and/or underlying soils. The Ex Situ Aggregate/Soil Base Stabilization (AMA) Process This particular blog will focus on the Ex Situ Aggregate/soil Base Stabilization Process. This overview is the first part of upcoming blogs that will feature all four of the AMA processes in more detail.
