公路沥青路面预防性养护措施验收标准

Acceptance Standard for Preventive Maintenance Measures for Highway Asphalt Pavement

预防性养护技术在一定程度上能改善旧路面的使用质量,如减少网裂、改善平整度、提高抗滑性能、防止水分下渗等。首先,深入调查分析了国内外预防性养护技术应用情况和研究文献;其次,从几种典型的预防性养护措施出发,分析当前国内外预防性养护措施验收标准的问题,并通过对已实施预防性养护措施路段进行跟踪检测,从采用抗滑性能、构造深度等验收指标角度,细化研究公路沥青路面预防性养护措施验收标准;最后,提出在预防性养护措施完成后验收时,应同时考虑其长期使用性能,进一步解决预防性养护措施完成后的验收难题,为预防性养护工程验收提供参考。

The preventive maintenance techniques can improve the service quality of old pavement to a certain extent, such as reducing mesh cracking, improving flatness, improving anti-skid performance, preventing water infiltration, and so on. Firstly, the application of preventive maintenance technology at home and abroad is investigated and analyzed. Secondly, starting from several typical preventive conservation measures and analysis of the current domestic and international acceptance standards for preventive maintenance measures, follow up and test the sections of preventive conservation measures that have been implemented. From the angle of adopting the acceptance indexes such as anti-skid performance and construction depth to study the acceptance standards of preventive maintenance measures for highway asphalt pavement. Finally, it is proposed that when the preventive maintenance measures are accepted after completion, their long-term performance should be considered at the same time, so as to solve the problem of acceptance after the completion of preventive conservation measures. It will provide reference for preventive maintenance projects.
