高掺量粉煤灰混凝土碾压路面的试验研究

Experimental Study on High Fly-ash Content Rolling Compacted Concrete Pavement(RCCP)

根据路面混凝土的特点,从混凝土配合比设计、粉煤灰超量取代水泥、粉煤灰水灰比效应等方面进行了"高掺量粉煤灰混凝土碾压路面的试验研究",取得了混凝土设计配合比的最优参数,在公路中应用取得了显著的经济效益。

According to the features of pavement concrete, this paper makes experimental study on high fly-ash content RCCP from aspects of the design of concrete composition, the replacement of cement with excessive fly-ash, and the water cement ratio effect of fly -ash, etc., and obtains the optimum parameters of concrete proportion design, having gained notable economic benefits in its application in highway project.
