Most road authorities conduct regular pavement condition surveys to collect data for pavement attributes including roughness, rutting, strength, skid resistance, cracking and texture. This data is used for a range of purposes including monitoring and predicting the performance of the network, determining the timing and selection of appropriate intervention treatments, and monitoring the performance of maintenance contractors. However, despite a long history of data collection across the Australasian road networks, no nationally adopted procedures exist for the collection of data and the validation of test equipment. Recognising the importance of high quality condition data, and in line with its strategic goal of promoting national uniformity of practice, Austroads members sponsored a project which had, as its aim, the development of standard specifications and test methods for the measurement of pavement roughness, pavement rutting, pavement surface macro-texture, pavement deflection measured with a falling weight deflectometer (FWD) and pavement deflection measured with a deflectograph. The paper also discusses how the specifications and test methods can be incorporated into contract documentation. Recommendations are also made regarding future areas of work identified during the course of the project. (a) For the covering entry of this conference, please see ITRD abstract no. 0612AR242E.
