层布式废旧轮胎钢丝沥青混合料抗裂性能研究
Research on the crack resistance of layered waste tire steel wire asphalt mixture
摘要
Abstract
In order to improve the crack resistance of asphalt mixture and promote the application of mixed length layered waste tire steel wire in asphalt mixture,the theoretical formula of effective length of waste tire steel wire was derived by establishing a crack resistance model for waste tire steel wire.Combined with the stress and crack conditions of asphalt pavement,the the science and feasibility of layered waste tire steel wire asphalt mixture were verified.The crack resistance of layered and randomly distributed waste tire steel wire as-phalt mixtures based on the amount of steel wire were studied by comparative experiments.The research results indicate that:(1)The crack resistance of the asphalt pavement with layered waste tire steel wire is better than that with randomly distributed waste tire steel wire;(2)The appropriate amount of layered waste tires steel wire is 0.5％to 1.5％;(3)When the appropriate dosage is used,the splitting tensile strength of the layered waste tire steel wire asphalt mixture increased by21.1％to 31.6％compared with the reference asphalt mix-ture,while the average linear shrinkage coefficient decreased by 12.1％to 13.8％.关键词
