What is the density of asphalt paving? - Quora
Answer (1 of 3): 2400kg per cubic metre is a good generic density. Sorry if you use the imperical system, I'm sure you can convert it easy enough. In real life though, it's a good idea to calibrate this figure based on tonnage used, average depth and coverage, especially if you are recieving mate...

How-to-Guide for Asphalt Pavement Compaction
Asphalt concrete mixtures cool quickly so it's important to compact while the mix is hot. Typically, asphalt comes out of the plant at about 300° F. At that temperature, it is relatively soft and is readily compacted. As it cools, it firms up and compaction becomes increasingly difficult. "The three most important factors when

The density requirements and the methods of measuring density vary considerably from state to state. Some states construct a control test strip, measure the density on the strip, and use that density as the target density for the project.

Factors Affecting Compaction – Pavement Interactive
Asphalt binder content also affects compaction. Asphalt binder lubricates the aggregate during compaction and therefore, mixes with low asphalt content are generally difficult to compact because of inadequate lubrication, whereas mixes with high asphalt content will compact easily but may shove under roller loads (TRB, 2000 [5]).
