The paper discusses advances in pavement design and rehabilitation since the Annual Transportation Convention of 1984. Recent Heavy Vehicle Simulator (HVS) testing has shown that subbases have a marked influence on the behavior and the long term life of pavement structures. The paper categorizes pavements into three classes in terms of subbase, i.e. granular (uncemented) and strongly and weakly cemented granular subbases, and discusses their respective strengths and weaknesses. A case is also made for the more widespread use of strongly cemented materials. Furthermore, additional parameters and criteria for new construction and rehabilitation design are suggested.
