A large amount of highways had been seriously destroyed since Wenchuan Earthquake in 2008, which had hindered earthquake relief work and broken reconstructed schedule for disaster area. Taken three reconstructed highways as investigation objects, eight types of gradation mixtures were examined to analyze the high-temperature stability and resisting crack at low temperature in cases of different controlled conditions. The results of tests showed that the recommended four types of gradation mixtures had better pavement performance than the other types of mixtures. Based on measures of pavement performance at three tested sections, the reasonable gradation range of mixtures put forward was suited for the special conditions in Longnan region.
