Experimental Study on Overlay Asphalt Mixture
To study the asphalt pavement performances on high temperature or its water stabilities, a series of tests, including high temperature stability test, immersion Marshall test, freeze-thaw splitting test, were finished. According to bailey method, initial quasi grading were calculated. Passing rate of 2.36 mm is respectively 36.3%, 33.1%, 36.1%, 38.7%, which is close to the initial quasi grading, namely 36%, 31.5%, 36%, 40%. Respectively at the test temperature of 60 °C, 68 °C, rutting tests were put forward. The results show that the mixture of gradation one has a higher temperature stability than the others in any case. Marshall immersion test and freeze-thaw test were conducted, optimizing with freeze-thaw splitting intensity ratio, which shows that the mixture of gradation one has a better water stability. To sum up, gradation one is recommended, designed by Marshall compaction molding with times of 100.
