How much does density matter? | Asphalt magazine

By Phillip Blankenship, Senior Research Engineer. Why do we want more density in a pavement? Density is the unit weight of a mixture. 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.
