摘要
为了改善路面在雨天的表现,使其达到排水路面的技术要求,对混合料的原材料进行了性能研究,选择合适的集料进行配合比设计,确定了矿料的级配范围与混合料的最佳油石比,并通过验证渗水系数等指标对混合料的排水等性能进行了研究。结果表明,彩色排水沥青混合料达到了排水路面的性能要求。彩色排水沥青路面因其良好的排水性能以及丰富的色彩在城市道路中的应用日益广泛。
In order to improve the performance of the road surface in rainy days to meet the requirements of the porous road,in this paper,the performance of raw materials of the mixture is studied,the aggregate is selected for the mixture design,and the gradation scope of the ore and the optimum asphalt content are determined.Then the performance of the drainage and other properties of the mixture are studied by verifying water permeability coefficient and other indicators.The results show that the mix design of the color porous asphalt mixture meets the performance requirements of the porous pavement.Color porous asphalt pavement has been increasingly applied in urban roads due to its drainage performance and rich colors.
