结合利智公路K116+855～K118+825路段旧水泥混凝土路面改造实践,对该路段路面破损状况和断板率调查进行计算分析。结果表明该路段破损状况为次,断板率评定等级为差,根据有关规范必须对该路段进行改造。同时,对改造方案中旧水泥混凝土路面破碎、基层、面层等施工工艺进行了总结。 Combined with the practice of old cement concrete pavement reconstruction on K116 + 855 ~ K118 + 825 section of Li-Zhi highway, the investigation on the damaged condition and the broken-plate rate of the pavement is calculated and analyzed. The result shows that the damaged condition of the road section is the second, and the rating of the broken board rate is poor. According to relevant regulations, the road section must be reconstructed. At the same time, the reconstruction of the old cement concrete pavement broken, grassroots, surface construction process were summarized.
