Construct boxouts if necessary for adjustment of fixtures. Comply with plans for the size and shape of the boxout. FORMWORK Construct formwork so concrete pavement is of size, shape, alignment, elevation, and position indicated and so that the pavement is within the tolerance limits of Section 3.10 Tolerances. Construct forms tight enough to prevent loss of concrete mortar. Fabricate for easy removal without hammering or prying against concrete surfaces. Clean forms and adjacent surfaces to receive concrete. Remove debris from forms just before placing concrete. Retighten forms and bracing before placing concrete, as required, to prevent mortar leaks and maintain proper alignment. Coat contact surfaces of forms with form-release agent, according to manufacturer's written instructions, before placing reinforcement, if used. The edge of previously placed concrete may be used as a form. Do not apply form release agent to previously placed concrete, unless prevention of bond between the new and the old concrete is desired. Formwork may be removed after cumulatively curing at not less than 50ºF (10ºC) for 24 hours after placing concrete, if concrete is hard enough to not be damaged by form-removal operations and curing and protection operations are maintained. and repair surfaces of forms to be reused in the Work. Damaged forms will not be acceptable. Apply new form-release agent. When are reused, clean surfaces, remove fins and laitance, and tighten to close joints. Align and secure joints to avoid offsets. STEEL REINFORCEMENT Comply with CRSI’s of Standard Practice” for placing reinforcement. “Manual Clean dowel and tie bar reinforcement of loose rust and mill scale, earth, ice, and other foreign materials. Place joint reinforcement at locations indicated on project drawings. Align dowels exactly centered over the joint line. Anchor dowel baskets securely into the subgrade. For paving lane widths greater than 12 ft (3.66 m), install a minimum of 4 stakes on the leave side of both basket legs.
