Evaluation of Moisture Susceptibility for Asphalt Mixtures
Types of asphalt mixture with different gradations and air voids were designed. Tests on their indirect tensile strength, compressive strength and resilient modulus of compression under single axle compressing were taken to study the effects of two forms of water immersion (hot water immersion and freeze-thaw split test) on asphalt mixtures mechanical performance and high temperature stability. Test results point out that water immersion decreased asphalt mixtures performance seriously and the effect of freeze-thaw split tests on asphalt mixtures performance is far stronger than that of hot water immersion. Asphalt mixtures performance is related with its gradation and percent air voids. Asphalt mixtures with different gradation are different in their percent air voids, suitable gradation can form framework and filling action obviously, so to yield mixture with suitable percent air voids and good water stability.
