Evaluation of Methods to Control Debonding
The purpose of the research was to evaluate various test methods for obtaining a measure of resistance to debonding of asphaltic concrete. The work was done in two phases. Phase 1 was involved principally with laboratory prepared specimens and Phase 2 with the changes in susceptibility to debonding of pavement cores as the pavement increased in service time. In Phase 1, the test methods were the immersion-compression, the University's double-punch, and a modified Lottman split-cylinder. The treatment included portland cement, lime, silane, BA-2000, and increasing the sand equivalent value. The results indicated that overall the portland cement treatment generally increased the 'wet' strength and the 'retained' strength and so was rated as the best. In Phase 2, the plant mixtures and cores from surfaces containing no treatment, BA-2000, and portland cement were evaluated with the immersion-compression test, the double-punch method, and the Tunnicliff split-cyclinder procedure. The double-punch method rated the untreated plant mixture as being acceptable, but the split-cylinder procedure rated it as not acceptable. Tests of cores by the immersion-compression test and double-punch method indicated good resistance to debonding; the split-cylinder procedure did not up to the first year.
