1.1 General

The purpose of this publication is to provide a guide to the principal types of asphalt, selection of asphalt mix type, selection of component materials, asphalt mix design, performance characterisation, and manufacture and placing of asphalt.

Asphalt is widely used in the construction and surfacing of roads in Australasia. The properties of asphalt are complex and its performance requirements vary considerably with the application. Engineers responsible for the design of works incorporating asphalt have a responsibility to acquire an adequate understanding of the properties of asphalt and appropriate usage as well as an understanding of the application of specifications and construction requirements.
