PDF Determining the Asphalt Binder Content of Hot Mix Asphalt

Some agencies allow the use of recycled HMA. When using recycled HMA, check with the agency for specific correction procedures. Binder in the HMA is ignited in a furnace. Asphalt binder content is calculated as the difference between the initial mass of the HMA and the mass of the residual aggregate, correction factor, and moisture content.

Calculations - California

Weight. The weight (tonnage) of a pile is determined by multiplying the volume by the density. CalRecycle's Solid Waste Cleanup Program has developed approximate pounds per cubic yard (lbs/cu yd) estimates for various materials. The actual density depends on the homogeneous nature (uniformity) of the pile in both void space and material type.
