Abstract:The first step in selecting the optimum rehabilitation strategy for a flexible pavement is identifying the cause of the existing pavement distress. The rehabilitation selection process is often straightforward once the cause has been identified. This report presents an updated summary of the techniques and interpretation guidelines that have been developed by the Texas Transportation Institute over the past two decades. A summary is presented of the different distress types frequently found on Texas flexible pavements. The possible causes for each are described together with guidelines on how to conduct a failure investigation. For each distress type a series of rehabilitation options are also presented.
