Pavement Preservation and Rehabilitation enables students to attain advanced professional knowledge for the evaluation and renewal of road pavements. It will impart cognitive skills to think critically about the methods used to assess the condition of road pavements, and about the materials employed to implement necessary rehabilitation treatments. The Unit examines the different ways in which pavements and wearing surfaces show distress, both structural and non-structural. Defects such as deformation, cracking and many others are described together with problems relating to safety and damage caused by external factors. Evaluation techniques are presented, which can be used to assess the condition of a pavement with respect to rideability and/or road user comfort, structural capacity and safety. The Unit then considers pavement rehabilitation options with details of restoration using a variety of materials and techniques by application of Whole of Life Costing.
