对于广泛采用二灰碎石材料做基层的一级公路以下的等级公路中,公路路面的横向裂缝、二灰碎石基层的冒浆及二灰碎石基层的成型不统一是路面基层施工中发现的常见问题。文章就其产生机理从材料、施工控制、气候、养护条件等方面进行了综合分析,并就具体工程实例(武港二级公路)从设计、施工、管理、养护几个方面提出了切实可行的防治措施。
For the graded roads under Grade I highway widely using lime-flyash gravel as the grassroots, the horizontal cracks in highway pavement, the grouting of lime-flyash gravel base and the formation of lime-flyash gravel base are not found in the construction of pavement basement Frequently Asked Questions. The paper makes a comprehensive analysis on its production mechanism from aspects of materials, construction control, climate, maintenance conditions and so on, and puts forward some feasible suggestions on design, construction, management and maintenance of the concrete project (Wugang Class II Highway) Prevention.
