Crack has been plagued Guangxi highway cement concrete pavement construction a major problem. In this paper, a comprehensive and systematic analysis of the completed highway cement concrete pavement causes , based on the calculation and analysis of field tests to determine the highway cement concrete pavement crack the main factors in the following areas : 1, subgrade uneven settlement , instability is a major factor in the early cracks ; 2 , construction techniques , materials and maintenance problems of improper methods ; 3 , temperature stress cracks ; 4 , poor drainage impact cracks ; solve this problem, the theoretical analysis and propose appropriate field data quality control objectives, on-site control methods. While the cement concrete pavement crack repair processing methods for systematic study , according to the extent of the damage cracks , summed put forward corresponding measures. These will enhance the future of Guangxi highway construction quality, reduce pavement cracks has a positive significance.
