【摘要】 针对混凝土路面拓宽的实际问题,对拓宽处理后容易产生的病害进行了分析,并吸取以往老路拓宽的工程经验,对于较小面积混凝土路面拓宽问题提出两种施工处理方法,并且通过对工后沉降及裂缝的观测、统计分析,对施工处理效果进行了总结,希望能对同类型工程有一定实践参考意义。更多还原

【Abstract】 Aiming at pratical problems existing in concrete pavement widening,it analyzed some disadvantages that can easily happen in the widened pavements.Having learnt lessons from old pavement widening,it proposed two construction treatment ways for solving the problems happened in small-area concrete pavement widening.And through observations on subsidence and cracks as well as the statistical analysis,the construction effects can be concluded.And it is expected to have practical reference significance to the engineerings of same style.更多还原
