How Many Tons Are In A Square Yard Of Asphalt 2020

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. These measurements are an approximation and therefore when you are ordering the quantity ensure that you add more asphalt …

Asphalt concrete - Wikipedia

Asphalt concrete (commonly called asphalt, blacktop, or pavement in North America, and tarmac, bitumen macadam, or rolled asphalt in the United Kingdom and the Republic of Ireland) is a composite material commonly used to surface roads, parking lots, airports, and the core of embankment dams. Asphalt mixtures have been used in pavement construction since the beginning of the twentieth century.

Theoretical Maximum Specific Gravity – Pavement Interactive

Overview. The theoretical maximum specific gravity (Gmm) of a HMA mixture is the specific gravity excluding air voids. Thus, theoretically, if all the air voids were eliminated from an HMA sample, the combined specific gravity of the remaining aggregate and asphalt binder would be the theoretical maximum specific gravity.
