摘要
透水路面混合料设计可采用《公路沥青路面施工技术规范》JTG F40-2004中开级配抗滑磨耗层配合比设计方法,结合本项目碎石精加工、高粘度改性沥青、木质纤维等材料特性,利用马歇尔稳定度试验、动稳定度、冻融劈裂试验、抗飞散损失率、渗水试验和低温弯曲试验的试验指标评价其抗高温性能、抗水损害性能和低温抗开裂性能。
The design of permeable pavement mixture can adopt the design method of open graded anti-skid wear layer mix proportion in the"Technical Specification for Highway Asphalt Pavement Construction"JTG F40-2004,combined with the characteristics of crushed stone precision processing,high viscosity modified asphalt,wood fiber and other materials in this project,and evaluate its high-temperature resistance performance using Marshall stability test,dynamic stability,freeze-thaw splitting test,anti flying loss rate,deep water test,and low-temperature bending test Water damage resistance and low-temperature cracking resistance.
