of asphalt binder in the mix. For our purposes, it is the amount of asphalt binder that effectively forms a bonding film on the aggregate surfaces. Air Voids -Air voids are small pockets of air between the coated aggregate particles in the final compacted mix. The durability of a hot mix asphalt pavement is a function of the air void content.

Hot Mix Asphalt | Asphalt Calculator | Calculate Aggregate

Overview Hot mix asphalt (HMA) pavement refers to the bound layers of a flexible pavement structure. Asphalt pavement material is a precisely engineered product composed of about 95 percent stone, sand, and gravel by weight, and about 5 percent asphalt cement, a petroleum product. Asphalt cement acts as the glue to hold the pavement together. Our HMA is mixed at our asphalt production

PDF Regressing Air Voids for Balanced HMA Mix Design

In volumetric mix design, the difference between air voids and voids in the mineral aggregate (VMA) controls the effective asphalt content. To increase the effective asphalt content in mixes, it is necessary to either target a lower air void content or increase the minimum VMA criteria . The objective of this study was to assess the

HMA Weight-Volume Terms and Relationships. Mix design, and specifically Superpave mix design, is volumetric in nature. That is, it seeks to combine aggregate and asphalt on a volume basis (as opposed to a weight basis). Volume measurements are usually made indirectly by determining a material’s weight and specific gravity and then calculating
