THE MECHANICAL PROPERTIES OF BITUMINOUS MATERIALS FOR ROAD BASES AND BASECOURSES (WITH DISCUSSION)

The results presented in this paper have been taken from a major research project aimed at examining those mechanical properties of road base and basecourse mixes with importance in structural design. The work began by assessing the materials currently used in the practice and then, against a background of research evidence from various sources. The paper also studied how the mixes could be improved, and has included field trials of those modified materials in order to ensure that they can be used in practical situations. The mechanical properties for pavement design described in paper include: (1) elastic stiffness under moving traffic conditions; (2) fatigue strength; and (3) resistance to permanent deformation.
