摘要
我国早期兴建高速公路时,往往采用水泥混凝土路面。这些高速公路由于通车运营时间较久远,加之水泥混凝土路面特有的接缝问题,导致很多水泥混凝土路面都存在板底脱空问题。本文就水泥混凝土路面板底脱空问题处理稍作探讨。
In the early construction of expressways in my country,cement concrete pavements were often used.Due to the long operation time of these expressways and the unique joint problem of cement concrete pavement,many cement concrete pavements have the problem of voids at the bottom of the slab.This paper discusses the problem of voiding at the bottom of cement concrete pavement.
