京沪高速公路通车后,随即发生路(桥)面泛白粉唧水,沥青路面纵横向开裂,水泥混凝土路面脱空与断板、桥(涵)墩台开裂等非常见性的工程病害。该类病害数量并不多,但发生在刚竣工不久,由于高速公路不宜轻易断交,为其修复造成困难,于是原位无损修复应运而生。 After the opening of the Beijing-Shanghai Expressway, there suddenly occurred non-peculiar engineering diseases such as road (bridge) surface pan white powder water, longitudinal and transverse cracking of asphalt pavement, emptying and breaking of cement concrete pavement and cracking of bridges and culverts. The number of such diseases is not much, but occurred just after the completion of the short, because the highway should not be easily broken off, causing difficulties for its repair, so in-situ lossless repair came into being.
