Cement Concrete Pavement

Cement concrete pavements were used in most airports built early in China. Nowadays the main task of airports is how to cover and reinforce damaged pavements. To ensure the life-span of pavement after covering, on the basis of analyzing the treatment methods of original cement concrete pavement, cement and asphalt concrete were used to realize the covering and reinforcement of old cement concrete pavement, and key technologies of Preventing reflective cracks of concrete pavement were put forward, which had a good result in practice

Through research on precast assembling structural design and construction technology in cement concrete pavement maintenance engineering, this paper brings forward reasonable size for precast assembling slab in cement concrete pavement maintenance engineering to improve original precast assembling construction technology and brings forward effective improvement measures for original construction technical difficulties. And simultaneously, through making a comparison of socioeconomic benefits among precast assembling maintenance mode, cast-in-place ordinary concrete maintenance mode , cast-in-place early-strength concrete maintenance mode and cast-in-place reinforced concrete, uses that precast assembling maintenance technology is a cement concrete pavement quick maintenance technology with extremely high performance price ratio.

Cement Concrete Pavement

Special load has produced serious damage to the concrete pavement because of the great gross weight and heavy axle load, but the present specification has not mentioned this kind of load. On this occasion, Several conditions of critical load are identified through ANSYS finite element model analysis and the formula through statistical regression analysis to the bottom maximum tension stress is drawn up. Which can not only guide the concrete pavement design under the special load but also the result may be referred by the other kinds of engineering.
