摘要
通过对旧水泥混凝土路面加铺沥青层中板底脱空、反射裂缝、水损害、层间结合、面层车辙、推移等关键技术问题进行深入分析,总结其对加铺改造后路面性能的影响,提出针对各关键技术问题的对策措施,从而可更好地指导旧水泥混凝土路面改造工程,使改造后路面的使用性能和使用寿命均得到提高和延长。
By deeply analyzing the key technical problems of asphalt overlay on existing cement concrete pavement,such as void under slabs,reflection cracking,water damage,interlayer bonding,surface rutting and slipping,summarizing the influence of those key problems on the performance of constructed asphalt overlay,the targeted countermeasures are brought forward so that it will direct the reconstruction of the existing cement concrete pavement more effectively,advance the service performance as well as lengthen the service life of the reconstructed asphalt overlay.
