摘要
Abstract
To increase application of other plant fibers in asphalt pavement,the lignin fiber,bamboo fiber and sisal fiber were added into AC-13 and SMA-13 mixture.The strength test,pavement performance tests and immersion dispersion test were used to analyze the asphalt mixture performance with different plant fibers,and the variance method was used to discuss influence of different factors on asphalt mixture performance.The test results showed that the asphalt mixture performance is obviously improved by addition of plant fiber,but the influences of different plant fibers on asphalt mixture performance are different.The improvement effect of lignin fiber,bamboo fiber and sisal fiber on strength and high temperature performance of asphalt mixtures is decreased successively.The low temperature crack resistance,water stability performance and anti-loose performance of asphalt mixture with different plant fibers is bamboo fiber＞sisal fiber＞lignin fiber.The performance of asphalt mixture with fiber is closely related to physical properties of fiber,especially the water absorption and tensile strength of fiber.The asphalt mixture with bamboo fiber has good strength and road performance,and lignin fiber can be replaced by bamboo fiber used in asphalt pavement.关键词
