9.2.2 Provide water curing according to 511.15 <strong>and</strong> 511.17, Method A.<br />

9.2.3 Deleted.<br />

9.3 Ensure that all forms are in place until the design h<strong>and</strong>ling strength is<br />

Holes for h<strong>and</strong>ling or setting are not permitted. Do not move members<br />

before the design h<strong>and</strong>ling strength <strong>of</strong> the concrete is reached, or shipped before<br />

the design strength <strong>of</strong> the concrete is reached. Ensure that the manufacturers have<br />

equipment necessary to h<strong>and</strong>le <strong>and</strong> transport the pieces without damaging them.<br />

10 Ensure that the hardened concrete contains a minimum <strong>of</strong> 4 percent<br />

entrained air.<br />

10.2.1 Keep the cylinders <strong>and</strong> matching culvert section together to guarantee<br />

the cylinders are matched with the corresponding culvert section; or, upon<br />

agreement by the <strong>Department</strong>, keep the cylinders at a location that will provide the<br />

same environment as the culvert sections.<br />

10.2.2 For each section <strong>of</strong> the culvert, produce <strong>and</strong> mark at least four<br />

cylinders so that they are identifiable with the matching culvert section.<br />

10.2.3 Conform to Supplement 1073 for acceptance.<br />

10.2.3.1 Ensure that cylinder strengths conform to Supplement 1073.<br />

10.3.3.2 Deleted<br />

10.4 Plug the core holes by using a concrete that is the same as that used in<br />

the section <strong>and</strong> cured according to Section 9.2, or by a non-shrink grout that<br />

exceeds the concrete design strength.<br />

11.0 The under-run in length <strong>of</strong> a section shall not be more than 1/2 inch (13<br />

mm).<br />

All changes to the project resulting from the manufacturer’s<br />

dimensional changes in the structure are at no charge to the <strong>Department</strong>.<br />

Ensure that the sections are free <strong>of</strong> fractures spalls <strong>and</strong> chips. Ensure<br />

that all surfaces have a smooth <strong>and</strong> regular finish being defined as a 1/4 inch<br />

variation within 4 feet (6 mm variation within 1.2 m).<br />

11.1 The internal dimensions shall vary not more than 1 percent from the<br />

design dimensions or more than 38 mm (1 1/2 inches), whichever is less. The<br />

haunch dimensions shall vary not more than 19 mm (3/4 inch) from the design<br />

dimension.<br />

11.4 Ensure that the maximum variation in the position <strong>of</strong> the reinforcement<br />

is 3/8 inch (9 mm), except that the cover over the reinforcement for the external<br />

surface <strong>of</strong> the top slab is not less than 2 inches (50 mm). The above tolerances or<br />

cover requirements do not apply to mating surfaces at the joint.<br />

11.5 Resubmit any change in reinforcement from the shop drawings for<br />

approval.<br />
