Pavement

Part 4J of the Guide to Pavement Technology provides information and guidance on: the classification and description of source rocks; the properties of source rock materials that need to be specified to ensure a durable end product; and quality assurance testing. It is recognised that local knowledge of material behaviour along with the experience and knowledge of the various construction authorities will give rise to differences in the test values and types of tests used in specifications. Austroads, however, encourages uniformity of practice in respect of specification of road construction materials and it is hoped that the publication of this Part will help facilitate this.
