Rehabilitation of Faulted Joints in Rigid Pavements
In New York many rigid pavements fail from joint-related distress. This is a gradual process, beginning with water infiltration, pumping, and loss of foundation support, and progressing to subsequent faulting and slab cracking. Loss of load-transfer capacity at joints and weakening of subbase support are accelerated by repeated applications of heavy wheel loads. Many techniques have been tested in New York through the years to alleviate the discomfort that faulting causes the driving public, and also to retard the rate of faulting (1,2,3). Among these have been asphalt shims, microsurfacing with asphalt emulsions, undersealing, asphalt overlays, slab grinding, retrofitting of load-transfer-devices (LTDs), and slab lifting with grout placed beneath the pavement. These methods have not proved to be completely successful or practical.
