maximum size of 3 inches. In this process the pulverized material shall be combined <br />uniformly with the base and subgrade to a depth specified in the Contractor's Mix <br />Design. Following the reclaimer, a roller shall be applied to compact the blended <br />material sufficiently to support traffic temporarily. The County requires removal of <br />approximately 2-1/2 in of pulverized material prior to addition of the stabilizing agent. <br />When the pulverizing and mixing step is complete, the material shall be graded, <br />watered, remixed, shaped, and compacted as necessary to establish proper grade and <br />uniform thickness and to support traffic temporarily. Water shall be applied if <br />necessary to obtain uniform moisture content as required by the Contractor's Mix <br />Design. The Contractor shall apply additional water at frequent intervals as needed to <br />suppress dust, preserve the surface, and maintain the specified moisture content. The <br />stabilizing agent shall then be applied and mixed to the depth specified by the County, <br />and grading and compaction of the combined base material shall proceed immediately <br />behind the mixing of the stabilizing agent. Before final grading and the addition of the <br />emulsion, the Contractor shall adjust the cross -slope, super elevation, and profile <br />grade by adding granular base material as required to provide the required grade and <br />cross slope for the road, or removing material. <br />c. Compaction: The Contractor may employ other compaction equipment and methods <br />in addition to the vibratory roller to accomplish the final grading and to compact and <br />finish the surface. Transverse joints shall be compacted by cross rolling parallel to the <br />joint. After the material has been compacted to load-bearing strength, the Contractor <br />shall proof -roll the prepared base in the presence of the Inspector. The County may, as <br />it deems necessary, direct the Contractor to correct areas of weakness and excess <br />moisture in the base by scarifying, aerating, and reworking shore sessions to the full <br />depth of the layer. If, after an area has been reworked and recompacted, it remains <br />soft or does not attain the required density, the County may direct the Contractor to <br />remove the material and replace it with Granular Base Material meeting the <br />requirements of these specifications. <br />5. Basis of Payment <br />a. Mobilization for reclaiming: No payment for mobilization shall be due for returning <br />the equipment to the site when it has been removed and returned for the Contractor's <br />own purposes or because of breakdowns and repairs, weather delays, labor problems, <br />accidents, or the like, or when work has been resumed after being stopped by the <br />County because of unsatisfactory materials, equipment, or performance. Payment for <br />Mobilization shall be Lump Sum for the project. <br />b. Reclaimed Asphalt Base, in place and accepted, shall be paid for at the contract unit <br />price per square meter or square yard, as indicated in the Bid Sheet. The area of work <br />for the purpose of payment shall be the overall length of each reclaimed lane times the <br />specified total base width for the lane. The total base width shall include the widening <br />width, if any, in which the reclaimer is to be used to blend new base material with the <br />pulverized layers. Payment under this item shall be full compensation for all work <br />included in or incidental to the reclaiming operation, for the grading, shaping, and <br />compacting of the Reclaimed Asphalt Base, for the mix design study, for furnishing, <br />delivering, and applying water, for applying and mixing and furnishing asphalt emulsion <br />or other stabilizing agent as specified, and for all other work and material incidental to <br />the reclaiming operation. <br />01025-27 Technical Specifications <br />F\Public Works\ENGINEERING DIVISION PROJECTS\1139-CR 512 Wbnd Resurfacing -Roseland Rd to US 1-SCOP\Admin\bid <br />documentsWlaster Contract Documents\Technical Specifications REVISED.doc <br />
