RECENT DEVELOPMENTS IN ASPHALT

The article reviews the Marshall bitumen mix design method, the object of which is to determine an economical blend and grading of aggregate and bitumen. Use of the method is intended to produce economical mixes which make use of locally available aggregates. The current UK empirical method of pavement design is shown to be unsatisfactory under heavy traffic conditions. It is suggested that a more flexible and fundamental engineering approach to pavement design is needed. Such an approach is the "analytical approach" developed by Nottingham University, features of which are discussed. Development work in the field of compaction is detailed and it is suggested that to obtain improved pavement performance improvements in compaction and specification are required. (TRRL)
