PAVEMENT RESTORATION MEASURES TO PRECEDE JOINT RESEALING

Various methods of rehabilitating jointed concrete pavement are discussed, based on the experience of the Georgia Department of Transportation. Special emphasis is given to techniques that may be required before joints are resealed. The measures discussed are stabilizing moving slabs, spall patching, slab replacement, edge drains, and grinding. Joint sealing is briefly described, and the use of low-modulus silicone sealant in resealing joints is emphasized. There is a need for adequate condition surveys of existing pavements so that the rehabilitation needs of an individual project can be established. A condition survey is also useful in establishing priorities among projects and in determining deterioration rates and performance of rehabilitated pavements. Attention is given to rehabilitated strategies, since it is only rarely that any one treatment is successful. For each individual treatment to be effective, a combination of treatments is required, such as slab stabilization and joint resealing. (Author)
