DENSITY OF ASPHALT CONCRETE - HOW MUCH IS

2011-1-7  The voids in an asphalt mixture are directly related to density; thus, density must be closely controlled to insure that the voids stay within an acceptable range. There has been much work that has shown that the initial in-place voids should be no more than approximately 8 percent and the in-

Density of Asphalt Concrete-How Much Is Needed?

Density is one of the most important parameters in construction of asphalt mixtures. A mixture that is properly designed and compacted will contain the optimum amount of air voids. Because density of an asphalt mixture varies throughout its life, the voids must be low enough initially to prevent permeability of air and water and high enough after a few years of traffic to prevent rutting caused by plastic flow.

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.
