Abstract:
The characteristics of average crack spacing models for continuously reinforced concrete pavement(CRCP)in AASHTO—1993 and Mechanistic-Empirical Pavement Design Guide(MEPDG)were analyzed. A total of 1 171 crack spacing data were collected from 29 CRCP experimental sections. Classifying, statistical analysis, distribution fitting and variance analysis were conducted by using the data. The parameters of AASHTO—1993 and MEPDG models were determined respectively, and two models were validated by using the data. Research result shows that cracks can be classified into six types according to the patterns, and CRCP crack spacing distribution is subject to four-parameter Dagum distribution. The differences of CRCP average crack spacings for different slab thicknesses at the same reinforcement ratio are not significant. AASHTO—1993 model overestimates average crack spacing with an error of 0.13 m, MEPDG model tremendously underestimates average crack spacing with an error of 1.7 m. 8 tabs, 4 figs, 15 refs.
