501.10 Curing. Immediately after finishing and when marring will not occur, cure the surface and exposed sides of concrete for at least 10 days. Do not leave the concrete exposed for more than 30 minutes during the curing period.

Provide initial curing by use of water method for 4 days. Cure according to Subsection 552.15(b). Cover the entire surface of the pavement and edges of the slab with water saturated mats. Extend the mats at least twice the thickness of the pavement beyond the edges of the slab.

Place the mats in complete contact with the surface. Use weights or other approved methods to maintain contact. After 4 days, remove water saturated mats and spray surface of pavement with liquid membrane curing compound according to Subsection 552.15(c). Cure remaining 6 days using liquid membrane curing compound.

Remove forms when the concrete has hardened sufficiently to resist damage, but no earlier than 12 hours after placing concrete. Protect the sides of the exposed slabs with a curing method equal to that provided for the surface. Prevent erosion of the base course beneath the exposed pavement edges until shoulders are constructed.
