Because of its carrying capacity, and low maintenance cost later, especially in recent years as the shortage of asphalt and road vehicle load increases, more and more extensive application of cement concrete pavement. But the cement concrete pavement is a mon highway engineering pavement as a surface form, now widely used in China in the highway, road and airport road in the city. Because of its carrying capacity, rigidity, high strength, good stability and low maintenance cost later, with the province39。s increased investment in transport, especially in recent years, as well as the shortage of asphalt road vehicle load increases, more and more extensive application of cement concrete pavement. However, due to its quality difficult to control than other surface structure, but also produced some quality problems, eating side, chipping, breaking boards, the wrong platform, in the open expansion joints, pump mud, etc., have a serious impact on the service life of concrete pavement and road road quality, limited investment to the country caused great waste. Therefore, how the construction process to take some measures to avoid or prevent the occurrence of mass incidents, to ensure the smooth construction, engineering and technical personnel has been the subject of study. Therefore, it is necessary to produce from the construction point of view of the mechanism of disease, thereby seeking to improve methods of construction technology. In this paper, cement concrete pavement causes of quality defects and their prevention and control measures in a brief introduction here.
