摘　　要：为解决武黄高速公路沥青路面龟裂病害问题,提出开普封层预防性养护方案。通过优化微表处矿料级配、提高材料指标要求等技术措施,解决了开普封层在重载渠化交通状况下易产生车辙、泛油、脱皮等问题。经过两年多的跟踪观测,试验路段经历了夏季连续高温和重载交通的考验,路面状况良好。In order to solve the cracking problem of asphalt pavement on Wuhuang Highway,the preventive maintenance scheme of cape seal was put forward.By optimizing the gradation of mineral materials at micro-surfacing sites and improving the requirements of material indexes,the problems of rutting,oil flooding and peeling of cape seals under heavy-duty channelized traffic conditions were solved.After more than two years of follow-up observation,the test section has undergone the test of continuous high temperature and heavy traffic in summer,and the pavement is in good condition.
