The report describes the procedures and results of a study to determine the extent and causes of pavement faulting on the Interstate System in Georgia. Several statewide faulting surveys were made during the course of the study. Comparisons are made on the severity of faulting taking into account the type of subbase courses used and the accumulative volume of heavy truck traffic. Recent design changes which have been made by Georgia in order to reduce the rate of faulting are discussed as well as present maintenance practices with respect to faulted pavements. It is concluded that the faulting of joints in Georgia is the result of erosional effects produced by the infiltration of surface water and repeated passage of heavy axle loads which is causing a loss of erodible material from the top of the subbase and from the shoulder area.
