The 2011 Austroads Guide to Pavement Technology Part 5: Pavement Evaluation and Treatment Design includes an interim procedure for the thickness design of foamed bitumen stabilised (FBS) pavements. This project aimed to validate the interim procedure to provide a more accurate predicted design life of these pavements. Australian and New Zealand road agencies contributed nine road trials of in-service FBS pavements to the project along with information on pavement design, construction and field performance. This report assesses the pavements against the data requirements for the validation of the interim procedure. It recommends collecting additional performance data from the field trials to improve understanding of the major factors contributing to the field performance and to validate the procedure.
