Knowledge of pavement technology is of critical importance for all transport agencies in Australia and New Zealand. Austroads and others (e.g. state road authorities, local government and industry) have amassed a great deal of knowledge on pavement technologies, techniques and considerations. The purpose of the Austroads Guide to Pavement Technology is to assemble this knowledge into a single authoritative electronic publication that is a readily available, accessible, comprehensive and free resource for practitioners in Australia and New Zealand.
Part 1: Introduction to Pavement Technology provides general information regarding the purpose and function of pavements, pavement types and their components, pavement materials, the types of pavements commonly in use today and an introduction to the fundamentals of pavement behaviour. A brief description of the other nine parts of the guide is also presented. The development of road pavements in Australasia is briefly discussed in a commentary.
This part is not intended to be referenced as a source document, but it provides the background to the Guide as a whole.
