PERFORMANCE AND DURABILITY OF BITUMINOUS MATERIALS. 17: A REPEATED LOAD COMPRESSION TEST FOR ASSESSING THE RESISTANCE OF BITUMINOUS MIXES TO PERMANENT DEFORMATION

The paper describes the use of a repeated load uniaxial compression test for assessing the permanent deformation resistance of bituminous paving mixtures. The test equipment, procedures, specimen preparation and test configuration are described in some detail. The merits of using a repeated load are demonstrated and results of tests on asphaltic concretes which show good correspondence with performance in wheeltracking experiments are presented. The case for the potential use of such a test system in designing bituminous mixtures to make best economic use of resources and as an instrument for performance specification is presented. The work forms part of a major project concerned with the development of simplified test methods to measure the mechanical properties of bituminous mixtures for use in a practical construction environment.
