The maximum unit weight is sometimes called the “solid density”. This value is based on the asphalt mixture’s maximum specific gravity – also known as the Rice value or G mm in Superpave. The maximum unit weight is determined by multiplying the Rice value by 62.4 pounds per cubic foot (PCF).

How much does density matter? | Asphalt magazine

Density is usually shown as a percent of maximum theoretical (Gmm) or the specific gravity of the in-place compacted density divided by the Gmm. Air voids is used interchangeably with density and is calculated: percent air voids = 100 – percent density. Density is achieved by compaction of the paver-laid asphalt-aggregate mixture.

May 09, 2016 · There are five factors that affect finished density of the asphalt mat: temperature of the mix itself, mat thickness, base temperature, environmental conditions (air temperature), and wind.

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.

For static steel-wheel rollers and vibratory rollers that have a maximum frequency of 2,400 vibrations per minute (vpm), 21¦2 mph typically is accepted as the maximum speed a roller should travel. For a vibratory
