Section 501 Section 501 10-foot straightedge at locations selected by the Engineer. The variation of the surface from the testing edge of the straightedge between any two contacts, longitudinal or transverse with the surface, shall not exceed 1/ 4 inch. Irregularities exceeding the specified tolerances shall be corrected, at no additional co st to the State, by the Contractor with an approved profiling device or by other means as directed by the Engineer. Following correction, the area will be retested to veri fy compliance with the specified tolerances. SECTION 502 - CONCRETE BRIDGE END PAVEMENT
502.01 Description . This work consists of bridge end pavement of concrete with
reinforcement as shown on the plans, constructed in one course on a prepared base in accordance with these specifications, and in r easonably close conformity with the lines, grades, thickness, and cross section shown on the plans or as directed. 502.02--Materials . On bituminous paving contracts, concrete for this work may be Class "B" Structural Concrete meeting the applicable requirements of Subsection 804.02. Sampling and testing of concrete for acceptance and control purposes shall be in accordance with Subs ection 804.02.3. Reinforcing steel shall meet the requirements of Subsection 711.02.
502.03 Construction Requirements .
502.03.1 General . The requirements specified for concrete pavement in Section 501,
shall apply in all respects to bridge end pave ment except where otherwise indicated in the specific requirements belo w, or on the plans. When the plans specify a certain thickness of asphalt under the bridge end pavement, the Contractor may substitute Class "B" Structural Concrete base in lieu of the asphalt. The concrete base shall be constructed in one course on a prepared base in accordance with these specifications, and in reasonably close co nformity with the lines, grades, thickness, and typical cross-sections as shown on the plans or as directed. The concrete base will be allowed to cure 24 hours prior to placement of the bridge end pavement. A one-inch premolded expansion joint will be required along the face of the paving bracket. See Section 403 for measurement and payment of substituted concrete base material.
502.03.2 Specific Requirements .
502.03.2 1--Final S creeding and Finishing . The final screeding shall be performed by
hand methods. The concrete shall be screeded longitudinally using the bridge floor for a gauge on one end, and a temporary bulkhead cu t and securely installed true to crown and grade on the other end. In the event the concrete pavement, adjacent to the bridge end pavement, has been previously poured, the end of the pavement shall be used as a gauge in lieu of the temporary bulkhead. The final finish of the bridge end pavement shall be that designated on the plans. If a finish is not designed, the finish shall be transverse tined finish.
502.03.2 2--Joints . Concrete bridge end pavement shall be constructed monolithically,
unless construction joints are speci fically indicated on the plans.
502.04 Method of Measurement . Concrete bridge end pavement, complete in place and
accepted, will be measured as sp ecified in Subsection 501.04.
502.05 Basis of Payment . Concrete bridge end pavement will be paid for at the contract
unit price per square yard in accordance with the methods as provided in Subsection 501.05, which price shall be full compensation for completing the work. Payment will be made under: 502-A: Reinforced Cement Concrete Bridge End Pavement - per square yard SECTION 503 - REPLACEMEN T OF CONCRETE PAVEMENT
503.01 Description . This work consists of replacing continuously reinforced concrete
pavement (CRCP), jointed reinforced concrete pavement (JRCP), or plain jointed concrete pavement (JCP) and the removal and replacement of base materials at locations designated on the plans or as determined by the Engi neer, all in accordan ce with the plans and specifications.
