我国水泥混凝土路面发展的历史较短,特别是水泥混凝土的高等级公路、高速公路还是近些年才开始大量修建。一部分新修运营才几年的道路,混凝土路面已经出现相当严重的病害。如路面板磨耗、剥落、开裂与断板、缺棱掉角或起拱、塌陷等,严重影响行车安全与舒适性,且其维修或重建费用巨大。 China’s cement concrete pavement development history is shorter, especially cement concrete high-grade highways, highways or in recent years began a large number of construction.

Such as road panel wear and tear, peeling, cracking and broken board, missing edge off or arch, collapse, etc., seriously affect traffic safety and comfort, and its repair or reconstruction costly.
