水-温-紫外线耦合作用下玄武岩纤维沥青混合料路用性能研究
Study on Road Performance of Basalt Fiber Asphalt Mixture under the Water-Temperature-Ultraviolet Light Oupling Effect
摘要
Abstract
In order to improve the performance of asphalt pavement and extend its service life,we carried out high and low temperature and water stability tests by mixed basalt fiber into asphalt mixture.Water-temperature-ultraviolet coupling test conditions were introduced to simulate the rapid aging environment of asphalt mixture in the field.We determined the best oil-stone ratio of AC-20C and BFAC-20C asphalt mixture by mix ratio design.We evaluated the influence of basalt fiber on the pavement performance of AC-20C asphalt mixture under the water-temperature-ultraviolet light coupling test conditions through the road performance test of asphalt mixture.The test results showed that:The high and low temperature performance and water stability of BFAC-20C asphalt mixture without water washing,freeze-thaw cycle and ultraviolet irradiation were significantly better than that of AC-20C asphalt mixture.The high and low temperature performance and water stability of the two asphalt mixtures decreased significantly under water erosion,freeze-thaw cycle and ultraviolet irradiation,BFAC-20C asphalt mixture decreased less.The addition of basalt fiber can significantly reduce the decay rate of pavement performance in the operation stage.关键词
