白霍一级公路水泥混凝土路面断板分析

Analysis on broken cement concrete pavement slabs of Baiyinhua to Huolinguole first class highway

极端寒冷地区修筑水泥混凝土路面存在诸多困难,而使用普通水泥(压折比较大)时水泥混凝土面板开裂一直是困扰施工人员的技术难题。文章结合白音华-霍林郭勒一级公路项目实际,对不可避免地存在的水泥混凝土路面断板进行分析并予以处治,使项目断板率显著降低。

There are many difficulties in building cement concrete pavement in extreme cold areas, and the cracking of cement concrete panel has been the puzzling technical problems to constructors. Combing with project reality of Baiyinhua to Huolinguole first class highway, this paper has analyzed and treated the inevitably existing broken cement concrete pavement slabs, which can significantly reduce the project broken slab rate.
