  • How much does density matter? | Asphalt magazine

    The normal target in-place density on a “dense” hot-mix asphalt pavement is 92 to 93 percent of Gmm (or 7 to 8 percent air voids). If a pavement has low density (usually defined as less than 92 percent of Gmm), the air voids are interconnected and premature pavement distresses can result.

    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.

  • Compaction of Hot Mix Asphalt Concrete

    Permeability The permeability of a well-compacted asphalt concrete is approximately 1.0 x 10- 9 feet per minute compared with 1.0 x 10-7 feet per minute for portland cement concrete (~). Thus, permeability will not be a problem for an uncracked section of asphalt concrete which has been well compacted.
