Abstract

Abstract

In order to understand the real development laws of transverse cracking for continuously reinforced concrete pavement (CRCP), a CRCP trial road on Leiyang-Yizhang expressway of Hunan Province had been investigated and tested for 5.5 a, and the test results of crack space and crack width were analyzed by using statistical method.Analysis result shows that CRCP transverse cracking can be divided into 3 periods with its age increase according to cracking development speed, including hardened cracking, transition cracking and stabilized cracking; in general, the variance coefficients of crack space and crack width are respectively 0.30~0.35 and 0.20~0.25;there is a fine power function relation between average crack space and CRCP age, there is a good linear function relation between average crack width and air temperature, and crack space accords with normal distribution.
