在寒冷地区建设水泥混凝土路面和场地,如何在设计施工中保证其质量,增强抵抗冻融破坏将是较迫切的任务,现根据多年的施工实践和观察,浅谈处理措施如下:1.基层强度与稳定水泥混凝土刚性面层对基础的不均匀下沉极其敏感,保证基础填土具有较高的强度和稳定性是不容忽视的。设计上要求不同土质应有不同的密实度指标,在施工工艺上要采用重型振动的压实机械。
In the cold areas of the construction of cement concrete pavement and site, how to ensure the quality of its design and construction, and enhance the resistance to freeze-thaw damage will be more urgent task, are based on years of construction practice and observation, on the treatment measures are as follows: 1 grassroots strength It is extremely sensitive to the non-uniform subsidence of the rigid concrete surface with stable cement concrete so as to ensure that the high strength and stability of the foundation fill can not be neglected. Design requirements of different soil should have different density indicators, in the construction process to use heavy vibration of the compaction machinery.
