摘要
为设计一种更加安全、质量可靠的低噪声排水路面,对最大骨料尺寸为8,10,13,20 mm的排水路面进行全面的物理性能测试,测试所用材料来源于试验室与现场厂拌的沥青混合料,并对建成及通车1年后排水路面的渗透性能、抗滑性能和交通噪声进行分析.结果表明,最大骨料尺寸为8 mm对应的排水路面表现出最大孔隙率和最优异的渗透性能;最大骨料尺寸为10 mm的排水路面抗滑性能最好;相比常规沥青路面与水泥混凝土路面,降噪排水路面的噪声等级明显降低,3种路面的噪声等级均随使用年限的累积而不断增加.
Abstract
To provide reference for the shaping design,noise reduction,safety performance,and dura-bility application under different traffic service conditions of subsequent noise reduction drainage pave-ment,a safer and more reliable low-noise drainage pavement was designed.The comprehensive physi-cal performance tests were conducted on drainage pavements with maximum aggregate sizes of 8,10,13,20 mm.The materials used for the tests were sourced from laboratory and field-mixed asphalt mix-tures.The permeability,skid resistance,and traffic noise of the drainage pavements were analyzed af-ter one year of construction and usage.The results showed that the drainage pavement with a maxi-mum aggregate size of 8 mm exhibited the highest porosity and the best permeability performance.The drainage pavement with a maximum aggregate size of 10 mm had the best skid resistance.In addi-tion,compared to conventional asphalt and concrete pavements,the noise level of the noise-reducing drainage pavement was significantly lower,and the noise levels of all three types of pavements in-creased with the cumulative years of use.
