following: 1 . Air temperature of 45 degrees F . to 80 degrees F . = 90 minutes maximum. 2 . Air temperature over 80 degrees F. with a retarder added to the mix = 90 minutes maximum. 3 . Air temperature over 80 degrees F . without a retarder added to the mix = 60 minutes maximum. E. PLACING CONCRETE The concrete shall be deposited on the grade in such a manner as to require as little re-handling as possible. It shall be deposited in successive batches in a continuous operation. The concrete shall be consolidated by suitable means so as to preclude the formation of voids or honeycomb pockets . F . PLACING IN COLD WEATHER The Contractor shall be responsible for protecting concrete placed in cold weather and any concrete damaged by frost action shall be removed and replaced at his expense. 3 .04 FINISHING A. The concrete shall be struck off, consolidated and finished with mechanical equipment in such a manner that after final finishing, it shall conform to the pavement cross section shown on the Plans. Hand finishing will be permitted in narrow widths, areas of irregular dimensions, and in the event of breakdown of the mechanical equipment, to finish the concrete already deposited on the grade. B . FINAL SURFACE FINISH The finished surface of the concrete pavement shall have a uniform skid resistant texture formed by a burlap drag or a stiff broom as required by the Engineer' s Representative, C . PAVEMENT EXPOSED TO RAIN DURING CONSTRUCTION 1 . The Contractor shall have, always available, materials to protect the surface of the plastic concrete against rain. Areas of the pavement surface where the texture has been damaged by the protective cover shall be re-textured and cured unless the concrete has hardened. Areas of pavement surface that exhibit a smooth sandy appearance after the rain ceases shall be textured and cured. An attempt shall be made to impart the specified texture to these areas before applying the membrane curing material. No other remedial work shall be required. Areas that have suffered some surface erosion and have coarse aggregate exposed shall be reworked by hand methods or with the finishing machine when the form paving method is used. Fresh concrete containing the same materials and properties as the pavement concrete shall be added to maintain an adequate supply in front of the screeds or machine to assure replacement of the concrete eroded from the surface. The surface shall then be textured and cured as specified. 2 . If pavement edges have been severely eroded and the concrete has not set, the edges shall 02752 — Concrete Paving 02752- 6
