ABSTRACT
This paper concerns asphalt base material technology developed to maximise resistance to permanent deformation and fatigue cracking.
The initial investigation identified criteria to be met during evolution. It was identified that the volumetric design approach should be introduced. This ensured that satisfactory aggregate skeleton and appropriate binder volume maximised durability properties of the material. The development of a suitable high performance polymer-modified binder was utilised to provide the stiffness and fatigue resistance characteristics.
The relevant properties were determined in the laboratory and in the field. This paper concentrated on specific values related to the principle aims of the development. The paper identifies the benefits in terms of pavement design by the use of the developed material and the identification of recommended further work subjects.
