Abstract

Abstract

Based on considering dowel loosened quantity, a doweled joint model of rigid pavement under repetitive loading was formed, a new method figured by the first critical load of load-transfered condition was put forward to evaluate load-transfered capacity at joint, the effect of load size, load position and dowel loosened quantity on joint load-transfered capacity was studied, the applicability of existing load-transfered index figured by direct deflection ratio under repetitive loading was analyzed, and compared with that of new load-transfered index which took dowel loosened quantity into consideration.It is found that the relationship between load and deflection near joint under repetitive loading is subsection linear character, there exists several levels of critical loads, the error between field test load and calculated first critical load in load-transfered condition is only 4.2%;direct deflection ratio changes from 57.3% to 71.5%, and load-transfered capacity with dowel loosened quantity changes from 0 to 51.9% after 4×10⁴ times repetitive loading.Analysis result shows that the model is reliable, the new method can actually reflect the load-transfered status of doweled joint in rigid pavement under repetitive loading.
