SEALING EXPERIMENTS TO COMPARE THE PERFORMANCE OF PAVING BITUMENS ON LIGHTLY TRAFFICKED ROADS IN HOT DRY CLIMATE AREAS

The Australian road research board has developed a laboratory test procedure which measures the resistance of paving bitumens to hardening by oxidation during handling and service. To confirm the utility of this test procedure, road experiments were laid in December 1977 with viscosity graded bitumens with a range of resistance to hardening AS Measured by the test. One experiment was laid in Western Australia and the other in Queensland, Both are initial seals on newly constructed pavements and both are located in a hot dry climate area on lightly trafficked routes. The rate of hardening and relative performance of the 13 bitumens used in the experiments will be monitored over a period of six years or more. The bitumens have differences in deformation and flow behaviour and, since this is likely to have some effect on relative performance in service, these properties have been evaluated in detail. This report gives the properties (including arrb durability test results) of the bitumens used, details of the laying of the two road experiments, and intended program for monitoring bitumen hardening.
