摘要
以体积法设计母体沥青混合料矿料级配,结合马歇尔、谢伦堡析漏和肯塔堡飞散试验确定混合料沥青用量。通过室内试验(车辙试验、浸水马歇尔试验)以及实验段现场性能检测(抗滑性能试验、渗水性能试验)评价其综合路用性能。结果表明,半柔性路面材料具有优良的高温稳定性、水稳定性和抗渗水性,但其抗滑性能稍显不足。
The ore gradation of matrix asphalt mixture is designed by volumetric method.The amount of mixture asphalt is determined by combining Marshall,Sherenburg analysis and Kentucky scatter tests.Its comprehensive pavement performance is evaluated by the laboratory tests(wheel tracking test and immersion Marshall Test)and the field performance tests of experimental section(anti-slide performance test and water seepage performance test).The results show that the semi-flexible pavement material has the excellent high-temperature stability,water stability and anti-water permeability,but its anti-slide performance is slightly insufficient.
