Third, you get the volume of the yard and multiply by the density and then change the cubic meter to ton asphalt. Standard Asphalt weight Standard asphalt density is 145lbs/ft3 or 2322kg/m3 The asphalt unit weight is 2243 per cubic meter. Therefore 2.4 ton of asphalt = 1 cubic meter. 1 cubic yard of hot asphalt mix weighs 2.025 tons or 4050 lbs.

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.
