Abstract
To investigate the impact of polypropylene fiber content on the road performance of the micro-surface mixture,several tests were conducted,including the wet wheel abrasion test,rut deformation test and low-temperature bending test.These tests aimed to assess the influence of different polypropylene fiber contents on the mixture's resistance to wear,water damage rutting,and low-temperature cracking under different oil-stone ratios.The results show that the content of polypropylene fiber should be less than 0.3%,and the wear value of wet wheel increases with the increase of polypropylene fiber contents when the oil-stone ratio is less than 7.0%,and decreases with the increase of polypropylene fiber contents when the oil-stone ratio is less than 7.0%.To a certain extent,polypropylene fiber can improve the rutting resistance of asphalt mixture at the micro-surface,In addition,through the low-temperature flexure test,it can be found that the addition of polypropylene fiber can greatly improve the low-temperature crack resistance of the mixture.关键词
