FAULT-REMOVAL PROCEDURES FOR RIGID PAVEMENT JOINTS. RESEARCH REPORT
Although faulting of transverse joints in portland cement concrete pavement generally has not been a problem in New York, a change in load-transfer devices between 1960 and 1972 is now producing significant faulting on pavements with high-volume truck traffic. This study was initiated to determine the most efficient method of rehabilitating faulted joints. Two methods of removing faults were investigated - 1) physically lifting slabs and grouting beneath them, and 2) diamond-blade grinding. Lifting and grouting proved difficult and time-consuming and did not completely remove all faulting, but grinding produced a level profile across the joints. Other factors were also included in the study, showing 1) that presence of a transverse crack within 25 ft of a joint increases faulting, 2) that the magnitude of differential vertical movement across a joint under load may be related to faulting, and 3) subsealing appears to have little effect on subsequent faulting.
