【 摘 要 】

This paper presents a comprehensive literature on moisture damage performance tests of asphalt mixtures. Moisture damage recognized as a cause for pavement distresses. The most common forms of moisture damage are adhesive failure between bitumen and aggregates. Adhesive failure is due to bitumen coating the aggregates are completely displaced by moisture, and stripping becomes visible in the asphalt mixtures. However, both quantitative and qualitative test do not focus on measuring the fundamental properties of the asphalt mixtures related to the moisture damage mechanisms of adhesion and cohesion. The results of the quantitative tests measured quantitatively, minimize the subjective evaluations of the test results. The quantitative are Tunnicliff and Root Conditioning (ASTM D4867) and Modified Lottman (AASHTO T283) test provide evaluation of moisture susceptibility of the asphalt mixture on the basis of strength and/or modulus ratio before and after conditioning. Other tests, such as Hamburg Wheel Tracking Device (HWTD) (AASHTO T324-04) provide measurement of moisture damage in terms of permanent deformation of the specimens. This paper is a review of the effectiveness of the selected available moisture damage performance tests. The analysis was conducted based on the success rate for each moisture damage performance tests.
