摘要
文章结合工程实例,分析了微表处混合料配合比设计要点,阐述了高速公路沥青路面微表处养护施工技术要点,并提出了质量控制措施。通过选取检测路段,分别对养护维修前后沥青路面超车道和行车道的抗滑摆值、渗水系数、车辙深度进行检测,数据分析结果说明养护质量达到了预期效果。
Based on engineering examples,this article analyzes the design points of mix ratio of micro-surfacing mixtures,describes the technical points for micro-surface maintenance construction of expressway asphalt pavement,and proposes the quality control measures.By selecting the detection sections,it tests the anti-slip values,water seepage coefficient and rut depth of asphalt pavement overtaking lane and carriageway respectively before and after maintenance,and the data analysis results show that the maintenance quality has achieved the expected results.
