Abstract:
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: 1. Repairs to deteriorated or damaged surface areas by the use of partial depth precast concrete slabs or bonded conrete in-situ repairs. 2. Mass-aread bush hammering, to remove deteriorate concrete and prepare old concrete surfaces for thin bonded overlays. 3. Bump cutting to correct concrete surface irregularities. 4. Texturing to improve anti-skid characteristics of slippery concrete surfaces.
