This chapter presents the objectives and steps required for cleaning and resealing joints in concrete pavements. Troubleshooting procedures for solving the problems potentially encountered in each operation are also included.

Rather, it is a common-sense guide for quality concrete pavement repair and resurfacing. It represents some current best-practices, as well as a good-faith representation of methods, materials, machines, and instruments currently available for field repairs of concrete pavements.
