Asphalt is a mixture of aggregate, sand, filler, bitumen and occasionally a number of additives. In an increasing number of countries old asphalt or demolition waste is recycled to replace virgin aggregate and part of the binder. In Europe there are at the moment approximately 4,000 mixing plants.

Hot-mix asphalts present a more durable solution; it is easy to install and to compact and it enables more effective bonding with existing asphalt pavement. There are two generic types of HMA: matrix dominated (Hot Rolled Asphalt, Mastic Asphalt) and aggregate dominated (Asphalt Concrete, Split Mastic Asphalt). Cement-based materials – these

Asphalt is produced in an asphalt plant. This can be a fixed plant or even in a mobile mixing plant. It is possible to produce in an asphalt plant up to 800 tons per hour. The average production temperature of hot mix asphalt is between 150 and 180°C, but nowadays new techniques are available to produce asphalt at lower temperatures. (See below).

Asphalt concrete 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 century. 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 …

Warm Mix Asphalt (WMA) is a new technology that was introduced in Europe in 1995. WMA offers several advantages over conventional asphalt concrete mixtures, including: reduced energy consumption, reduced emissions, improved or more uniform binder coating of aggregate which should reduce mix surface aging, and extended construction season in temperate climates.

The first fatigue study on hot mix asphalt (HMA) was performed at Nottingham University in the 1950s; since then, a massive amount of work has been done. This paper provides a review survey of fatigue studies of asphalt mixtures; this survey includes demonstrating fatigue test techniques, test modes, load configurations, approaches, and criteria.
