Until recently, cutting operations, repairs, and new surfacings on concrete pavements often have necessitated closures for extended periods. A range of equipment and techniques developed in England and recently introduced in the U. S. A. make it possible for the following operations to be carried out during off-peak periods without extended closures to traffic: repairs to deteriorated or damaged surface areas by the use of partial depth precast concrete slabs or bonded concrete in-situ repairs; mass-area bush hammering, to remove deteriorated concrete and prepare old concrete surfaces for thin bonded overlays; bump cutting to correct concrete surface irregularities; texturing to improve anti-skid characteristics of slippery concrete surfaces. These processes, which are carried out dry, offer advantages in terms of speed of operation over previous methods.
