How Much Does Density Matter?

Density is a desired quality of asphalt pavements, and is achieved by compaction of the paver-laid asphalt-aggregate mixture. The squeezing together of the aggregates increases their surface-to-surface contact and inter-particle friction, resulting in higher stability and pavement strength. With this in mind, this article focuses on the potential performance of increasing pavement density as it relates to brittleness (fatigue) and rutting (flow number).
