Category:403 asphaltic concrete pavement - Engineering ...

The density (PF density), asphalt content (PF AC), VMA (PF VMA), and air voids (PF Va) pay factors are calculated for each lot using the corresponding PWL t and the equations in Standard Specification Section 403.23.7.2. The total pay factor (PFT) is then calculated for each lot using the average of the individual pay factors.

How much does density matter? | Asphalt magazine

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.
