DENSITY OF ASPHALT CONCRETE - HOW MUCH IS NEEDED?
The density produced during the mix design should not be used as the reference density since the laboratory properties will be somewhat different from test results on plant produced materials.Sometimes aggregates break down during mix production,creating an increase in dust,thus altering the properties of the compacted asphalt mixture.

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 to gather for ...
