HOW TO HALT PREMATURE PAVEMENT FAILURE

Many older pavements in New York fail prematurely because of joint failure. The major problem is corrosion of load-transfer devices, with water infiltration and substantial vertical deflection creating conditions for pumping, loss of support, and subsequent faulting and slab cracking. This study was specifically designed to investigate long-term solutions to faulting problems, using various ACC overlay thicknesses on rigid pavements constructed from 1960 to 1973 with two-component malleable-iron load-transfer devices. In New York State, two long-term rehabilitation techniques have been used on faulted pavements -- load-transfer retrofit and ACC overlay. This study considered how initial faulting and overlay thickness affect fault return.
