旧水泥混凝土路面改造的技术方案很多,目前工程实践中改善和提高旧水泥路面服务性能的主要改造方案仍是加铺沥青混凝土路面(即“白改黑”),但是反射裂缝问题是“白改黑”工程中需要解决的首要问题,防“反”技术是水泥混凝土路面“白改黑”工程成功与否的关键。本文首先总结目前使用的各种防治反射裂缝的技术措施,然后对比了各种防治措施的技术特点,确定各种防反措施的优劣势。
There are many technical solutions for the reconstruction of the old cement concrete pavement. At present, the main improvement project of improving and improving the service performance of the old cement pavement in engineering practice is still to add asphalt pavement (ie “white to black”), but the reflective cracking problem is “White to black” project to solve the most important issues, anti- “anti ” technology is the cement concrete pavement “white to black” key to the success of the project. This paper first summarizes the various technical measures used to prevent reflection cracks, and then compares the technical features of various control measures to determine the advantages and disadvantages of various anti-countermeasures.
