城市道路路面半刚性基层试验研究

Experimental Study on Semi-rigid Base of Urban Road Pavement

半刚性基层由于具有强度高、刚度大、承载能力强、原材料价格相对便宜等特点,因而目前在国内高等级公路和城市道路建设中被广泛采用。在路面设计时,半刚性基层设计参数的选取、对材料设计和性能的正确把握,关系到道路建设的经济性和安全性。该文通过室内试验和现场试验,对半刚性基层设计参数、材料设计和性能进行了深入研究分析,为路面设计提供参考。

The semi-rigid base has been widely used in the construction of high-class highway and the urban road in China because of high intensity,high rigidity,strong carrying capacity and relatively cheap price of raw materials.The selection of design parameters of the semi-rigid base and the correct grasping of material design and performance are related to the economy and safety of road construction in the pavement design.Through the indoor experiment and field experiment,the article deeply studies and analyzes the design parameters,the material design and performance of semi-rigid base able to provide the reference for the pavement design.
