增粘沥青抗裂磨耗层在国省干线路面养护中的应用

合理的预防性养护措施可以延缓路面大中修时间，延长路面使用寿命。以某国道养护工程为依托，在对养护路段路面开展技术检测的基础上，提出采用增粘沥青抗裂磨耗层技术，介绍了增粘沥青抗裂磨耗层工程应用要点。结果表明，增粘沥青抗裂磨耗层能够解决路面存在的抗滑不足问题，有良好的工程应用前景。

Application of tackifying asphalt anti cracking wearing course in national and provincial trunk pavement maintenance

Reasonable preventive maintenance measures can delay the time of large and medium-sized maintenance and prolong the service life of pavement. Based on the maintenance project of a national highway, on the basis of the detection of the pavement technical condition of the maintenance section, this paper puts forward the technology of adopting the anti cracking wearing course of tackifying asphalt, and introduces its engineering application points. The field test results show that the anti sliding problem of the original pavement is solved by using the anti cracking wearing course of tackifying asphalt, which has good engineering application prospect.
