CONCRETE PAVEMENT JOINTING AND SEALING METHODS

A comprehensive program to study the performance of concrete pavement joint sealing materials and related practices is being conducted in Pennsylvania. The experimental pavement consisted of combinations of various sealant materials, joint shapes, and slab lengths; a total of 1,020 transverse joints were involved. The materials include conventional "improved" rubberized asphalt, cold-poured, 2-component polymers, and preformed neoprene seals. Various sizes of step-cut joints were tried. These joints have a wider cut at the top to improve the width-to-depth ratio of the sealant. Shorter-than-normal slab lengths were also tested. Preliminary observations indicate that the improved rubberized-asphalt sealant performs better than the conventional-grade material. The cold-poured polymers were found to require careful mixing and handling to obtain satisfactory results. When properly placed, these materials also appear to provide good sealing qualities. The neoprene seals are also performing very well. Preliminary results indicate that the shorter slab lengths offer better joint seal performance and the 1/2-in. wide x 3/4-in. deep joint cut is more satisfactory than the method conventionally used.
