inlets, structures, walks, and other fixed objects, <br /> unless otherwise indicated . <br /> (2) Locate expansion joints at 30 feet o. c. for concrete <br /> walks , unless otherwise indicated . <br /> (3) Extend joint fillers full width and depth of joint, and not <br /> less than one-half inch below finished surface where <br /> joint sealer is indicated . If no joint sealer, place top of <br /> joint filler flush with finished concrete surface . <br /> (4) Fumish joint fillers in one-piece lengths for the full <br /> width being placed , wherever possible . Where more <br /> than one length is required , lace or clip joint filler <br /> sections together. Pieces shorter than four inches <br /> shall not be 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 <br /> material . Remove protection after concrete has been <br /> placed on both sides of joint. <br /> (6) Fillers and Sealants: Comply with the requirements <br /> of these specifications for preparation of joints, <br /> materials installations and performance , and as <br /> 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 <br /> and 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 <br /> shall not be acceptable . Distribute concrete as required to remove <br /> surface irregularities, and refloat repaired areas to provide a <br /> continuous smooth finish . <br /> 3. Work edges of slabs, gutters , back top edge of curb, and formed <br /> joints with an edging tool , and round 10-112" radius, unless otherwise <br /> indicated . Eliminate any tool marks on concrete surface . <br /> 4. After completion of floating and when excess moisture or surface <br /> sheen has disappeared , broom finish sidewalks by drawing a fine- <br /> hair broom across concrete surface, perpendicular to a line of <br /> pedestrian traffic. <br /> 5. Do not remove forms for 24 hours after concrete has been placed . <br /> After form removal , clean ends of joints and point-up any minor <br /> honeycombed areas. <br /> D.
