DEVELOPMENTS IN HIGHWAY PAVEMENT ENGINEERING 1. CHAPTER 4--COMPACTION OF BITUMINOUS MIXTURES

In general, compaction of bituminous materials has been considered satisfactory in the UK and poor performance of pavements has rarely been ascribed to inadequate compaction. Recently however, an appraisal of the state of compaction of dense roadbase and basecourse macadams being achieved in current practice has revealed a considerable variation of compaction at different sites and has indicated there is considerable scope for improving compaction in the critical wheel path zones whose behaviour largely determines the structural performance of the road. This chapter considers the important factors determining the level of compaction on the road and describes recent developments directed towards improving the compaction of dense roadbase and basecourse macadam. The relationship between compaction and parameters related to pavement performance enables an assessment to be made of the benefits to be derived from improving compaction. Finally, brief mention is made of the development of new materials, in which studies of their compactibility plays an important role. /Author/TRRL/
