Asphalt concrete - Wikipedia

Asphalt concrete (commonly called asphalt, blacktop, or pavement in North America, and tarmac, bitumen macadam, or rolled asphalt in the United Kingdom and the Republic of Ireland) is a composite material commonly used to surface roads, parking lots, airports, and the core of embankment dams. Asphalt mixtures have been used in pavement construction since the beginning of the twentieth …

How much does density matter? | Asphalt magazine

Density 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. The normal target in-place density on a “dense” hot-mix asphalt pavement is 92 to 93 percent of ...
