国外发达国家和国内部分省份对微表处混合料进行了系统研究,而且成功地应用于高速公路预防性养护工程,但是我省微表处技术起步较晚,室内配合比设计研究较少,严重制约我省微表处技术全面快速的发展。论文对微表处混合料原材料、矿料级配、配合比等全面进行试验研究,确定了各种材料的比例用量,可拌和时间、粘聚力、湿轮磨耗、黏附砂量和轮辙变形指标均满足规范要求,各项性能较好。论文研究结果将对微表处混合料配合比设计及其养护施工具有重要的指导意义。
Some developed countries in our country and some provinces in our country systematically studied the mixture of micro-surfacing and successfully applied in the preventive maintenance project of expressway. However, the technology of micro-surfacing in our province started relatively late with less research on the mix design in the interior, Restricting the province’s micro-surfacing technology in an all-round and rapid development. The paper comprehensively studied the raw materials, mineral aggregate gradation and compounding ratio of micro-surfacing, determined the proportion of various materials, mixing time, cohesion, wet wheel wear, adhesion sand and tire deformation The indicators meet the specifications, the performance is better. The results of the thesis will have important guiding significance for the mix design of micro-surfacing and its curing construction.
