摘要
为研究薄层罩面技术在沥青路面预养护中的运用,论文对薄层沥青混合料性能进行测试,确定最佳级配方案为级配1,最佳油石比为5.4%,并依托实际工程,对道路行驶质量指数RQI、车辙深度指数RDI、抗滑性能指数SRI进行2年追踪。结果表明,薄层罩面在实际沥青路面养护工程中应用良好。
In order to study the application of thin layer coating technology in the pre-maintenance of asphalt pavement,the performance of thin layer asphalt mixture was tested,and the best gradation scheme was determined as gradation 1,and the best asphalt-stone ratio was 5.4%.Based on the actual engineering,RQI of road driving condition,RDI of rut depth and SRI of skid resistance were tracked for two years.The results show that thin coating can be well applied in asphalt pavement maintenance engineering.
