<br />02510 - 5/5 <br />pavement, shall be carefully rounded to a 1/4-inch radius except as otherwise <br />indicated. A well-defined and continuous radius shall be produced and a smoother, <br />dense mortar finish obtained. All concrete shall be completely removed from the top <br />of the joint filler. <br />B. All joints shall be checked with a straightedge before the concrete has become <br />nonplastic and, if one side of the joint is higher than the other or the entire joint is <br />higher or lower than the adjacent slabs, corrections shall be made as necessary. <br />3.11 CURING <br />A. After the finishing operations have been completed and as soon as the concrete <br />has hardened sufficiently that marring of the surface will not occur, the entire <br />surface and the edges of the newly placed concrete shall be covered and cured <br />with membrane curing compound. <br />B. Curing compound shall be uniformly applied to the surfaces to be cured, in a single <br />coat, continuous film, at the rate of one gallon to not more than 200 square feet, by <br />a mechanical sprayer. <br /> <br />C. Curing compound shall not be applied during periods of rainfall. Curing compound <br />shall not be applied to the inside faces of joints to be sealed. Should the film <br />become damaged from any cause within the required curing period, the damaged <br />portions shall be repaired immediately with additional compound. Upon removal of <br />side forms, the sides of the slabs exposed shall immediately be coated to provide a <br />curing treatment equal to that provided for the surface. <br /> <br /> <br />END OF SECTION
