1042. 3(c) 1042. 3(e) the surface tolerance has been checked and high points are removed as specified in Section 501.3(o). Provide adequate lighting, as indicated on the field operation QC Plan, for placement not completed in the daylight. Ensure lighting allows proper placement, testing, and inspection operations of the entire surface area and until curing covers are placed over the surface area.
if applicable. D o not use membrane- forming or monomolecular curing compounds:
follows: Maintain cure temperatures of 45F or greater throughout the wet and dry cure period. Do not count as a curing day, a day on which the curing temperature drops below 45F . If the curing temperature falls below 35F during the curing period, the Department will consider the work unsatisfactory, and it will be rejected. Protect the overlay using methods as specified in Section 1001.3(p)4 during cool weather and
period. Soak burlap for a minimum of 48 hours before placement. Re- wet burlap as needed before placement. Promptly cover the surface with a double layer of clean, wet burlap within 15 feet of strike -off from the finishing machine. Place burlap so each strip overlaps one- half its width. Minimal marking of the surface from curing covers is allowed. Maintain burlap in a fully wet condition using misting hoses , fogging machines that span the entire burlap covered surface, or other approved devices until the concrete has set sufficiently to support foot traffic. At that time, place soaker hoses on the burlap to maintain continuous saturation of burlap over the entire deck surface. At a minimum, place soaker hoses at grade breaks and high sides of superelevations to ensure continuous saturation. Secure burlap to prevent lifting or displacement due to adjacent construction operations or wind. C ure the surface according to Table A.
according to Table A. Maintain the surface of the overlay in a dry condition for the entire dry cure period. Cover the surface with waterproof coverings as required. If the overlay surf ace becomes wet during the dry period, extend the dry cure period to the equivalent time that the overlay surface was wet.
