Asphalt concrete - Wikipedia

Asphalt concrete is a composite material commonly used to surface roads, parking lots, airports, as well as the core of embankment dams. It consists of mineral aggregate bound together with asphalt, laid in layers, and compacted. The process was refined and enhanced by Belgian inventor and U.S. immigrant Edward de.

IAPA :: Parking Lots - Illinois Asphalt Pavement Association

Most parking lots in Illinois are built on a foundation of native subgrade soils and an aggregate layer (typically dense graded aggregate) to provide load-carrying structure and to improve the working platform for the asphalt paving materials. Following the placement and compaction of the soil and aggregate layers, two or.

Proper drainage ensures lasting asphalt pavement structures .

The proper design of the drainage system for a particular pavement is of paramount importance. Reducing the moisture content of the granular layer and subgrade through the use of effective drainage directly affects fatigue cracking of the Hot Mix Asphalt (HMA) surfaces and thus the life of the pavement. Drainage of the.

Stable asphalt binding layers | CFF & Co. KG - Passionate .

Asphalt binding layers connect the base course to the surface course. Most shearing stress is transferred in the binder layer, which possess specific requirements for their stability and deformation resilience. They are intended for asphalt roads of load classes BK 100, BK 32, BK 10 and BK 3,2 according to RStO 12.

Pavement Terminology — Pavement Engineering Inc.

It involves coring through multiple layers of pavement to determine composition, characteristics of the native soil and moisture content. Core test data is referred to as the R-value (resistance value), which determines how deep the subgrade needs to be to support the aggregate base and asphalt concrete surface layer that.
