502Concrete 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 Subsection 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 pavement except where otherwise indicated in the specific requirements below, 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 Screeding 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 specifically indicated on the plans.
