used unless specifically shown as such. <br />(5) Protect the top edge of the joint filler during concrete <br />placement with a metal cap or other temporary material. <br />Remove protection after concrete has been placed on <br />both sides of joint. <br />(6) Fillers and Sealants: Comply with the requirements of <br />these specifications for preparation of joints, materials <br />installations and performance, and as herein specified. <br />C. CONCRETE FINISHING <br />1. After striking -off and consolidating concrete, smooth the surface by <br />screening and floating. Use hand methods only where mechanical <br />floating is not possible. Adjust the floating to compact the surface and <br />produce a uniform texture. <br />2. After floating, test surface for trueness with a 20 ft. straight edge. <br />Variations exceeding one-third inch for any two points within 10 feet shall <br />not be acceptable. Distribute concrete as required to remove surface <br />irregularities, and refloat repaired areas to provide a continuous smooth <br />finish. <br />3. Work edges of slabs, gutters, back top edge of curb, and formed joints <br />with an edging tool, and round 10-1/2" radius, unless otherwise <br />indicated. Eliminate any tool marks on concrete surface. <br />4. After completion of floating and when excess moisture or surface sheen <br />has disappeared, broom finish sidewalks by drawing a fine -hair broom <br />across concrete surface, perpendicular to a line of pedestrian traffic. <br />5. Do not remove forms for 24 hours after concrete has been placed. After <br />form removal, clean ends of joints and point -up any minor honeycombed <br />areas. <br />D. CURING: <br />Protect and cure finished concrete paving and walks, as required. Use moist - <br />curing methods for initial curing whenever possible of approved concrete curing <br />compounds. <br />E. REPAIRS AND PROTECTION: <br />1. Repair or replace broken or defective concrete, as directed by Engineer. <br />2. Drill test cores where directed by Engineer, when necessary to determine <br />magnitude of cracksor defective areas. Fill drilled core holes in <br />satisfactory pavement areas with Portland cement concrete bonded to <br />pavement with epoxy resin grout. <br />3. Protect concrete from damage until acceptance of work. When <br />construction traffic is permitted, maintain pavement as clean as possible <br />by removing surface stains and spillage of materials as they occur. <br />02576-7 <br />
