    Abstract

    The use of full-depth asphalt pavement to construct and rehabilitate heavily loaded urban roads has grown rapidly in Western Australia over the past three years. Five different types of asphalt mixes were produced in the laboratory according to the Australian Standard methods of sampling and testing asphalt to modify payment performance mixture. The main role of this research is to evaluate and assess the hot-mix asphalt pavement performance characteristic for Western Australia road. In this study, laboratory test for tensile strength, resilient modulus, wheel tracking, asphalt binder content, and Marshall Compaction test were taken and analyzed for each asphalt mixture. Results showed that AC20-75 and AC14-75 Blow asphalt mixes were more efficient and effective in pavement performance as compared with the other mixes. In general, all asphalt mixes that are used in this study can notably strengthen and stabilize the mixture stiffness of asphalt. The modification effect rank can be described as AC20-75 Blow > AC14-75 Blow > AC14-50 Blow > AC7-50 Blow > SMA7-50 Blow in this research.
