I . DESCRIPTION Except as specified herein, construct Jointed Plain Concrete (JPC) Pavement in accordance with the Department's Standard and Supplemental Specifications, Special Provisions and Special Notes, and Standard and Sepia Drawings, current editions, and as directed by the Engineer. Section references are to the Standard Specifications. Furnish all materials, labor, equipment, and incidentals for the following work: (1) Remove existing pavement and replace with JPC Pavement; (2) Maintain and control traffic; and (3) All other work specified as part of this contract. I I . MATERIALS The Department will sample and test all materials according to the Department’s Sampling Manual. Make the materials available for sampling a sufficient time in advance of use, to allow for the necessary time for testing, unless otherwise specified in these notes. A. Maintain and Control Traffic. See Traffic Control Plan. B. Jointed Plain Cement Concrete Pavement. Use JPC Pavement/24. At Contractor’s request, and at no additional cost to the Department, the Engineer may approve other high early strength rapid setting concrete. The Department will allow either central mixing or truck mixing. C. Joint Sealant. Use Hot-Poured Elastic, no alternates. I I I . CONSTRUCTION METHODS A. Maintain and Control Traffic. See Traffic Control Plan. B. Site Preparation. Be responsible for all site preparation, including but not limited to, incidental excavation and backfilling; removal of all obstructions or any other items; disposal of materials; sweeping and removal of debris; shoulder preparation and restoration; temporary and permanent erosion and pollution control; final dressing, clean up, and seeding; and all incidentals. Perform all Site Preparation only as approved or directed by the Engineer. C. Pavement Removal. Consider pavement removal locations and dimensions shown on the drawings to be approximate only; the Engineer will determine exact locations and dimensions at the time of construction. Prior to removal, saw-cut (incidental to remove pavement) existing asphalt pavement at locations directed by the Engineer to provide a neat edge where new concrete will adjoin existing asphalt. Remove underlying DGA/stone or other materials to depths as outlined on the attached drawings or as directed by the Engineer to provide for the specified thickness of stone/JPC pavement outlined in this proposal. D. Concrete Pavement Replacement. Prior to placing JPC Pavement, obtain the Engineer’s approval of proposed method of construction for ensuring and establishing a smooth profile. Immediately after removing asphalt pavement, stabilize the base as outlined in the attached notes or as directed by the Engineer and place the replacement JPC in a continuous operation in accordance with the Traffic Control Plan and as directed by the Engineer. Construct the replacement JPC Pavement with a minimum depth of 10 inches; however, transition the finished grade to match adjacent pavement that is to remain in place; therefore, the actual thickness of the pavement may be greater than 10 inches in some areas. Consolidate the concrete, strike off, machine finish with a vibrating or roller screed, and straightedge the plastic concrete with a straightedge conforming to Section 501.02.18. The profile of the finished pavement shall conform to the Category B Requirements of Section 501.03.19(B). E. Joint Sealing. Saw, clean, and seal transverse and longitudinal joints as shown on the standard drawings and as directed the Engineer. F. Traffic Signal Detection. Contractor shall notify Department prior to beginning work so that provisions for signal detection can be put into place.
