Division 2 - Technical Provisions, IRC -1639 <br />of 3 inches. In this process the pulverized material shall be combined uniformly with the base <br />and subgrade to a depth specified in the Contractor's Mix Design. Following the reclaimer, a <br />roller shall be applied to compact the blended material sufficiently to support traffic <br />temporarily. The County requires removal of approximately 2-1/2 in of pulverized material <br />prior to addition of the stabilizing agent. When the pulverizing and mixing step is complete, <br />the material shall be graded, watered, remixed, shaped, and compacted as necessary to <br />establish proper grade and uniform thickness and to support traffic temporarily. Water shall <br />be applied if necessary to obtain uniform moisture content as required by the Contractor's <br />Mix 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, and <br />grading and compaction of the combined base material shall proceed immediately behind <br />the mixing of the stabilizing agent. Before final grading and the addition of the emulsion, the <br />Contractor shall adjust the cross -slope, super elevation, and profile grade by adding granular <br />base material as required to provide the required grade and cross slope for the road, or <br />removing material. <br />c. Compaction: The Contractor may employ other compaction equipment and methods in <br />addition to the vibratory roller to accomplish the final grading and to compact and finish the <br />surface. Transverse joints shall be compacted by cross rolling parallel to the joint. After the <br />material has been compacted to load-bearing strength, the Contractor shall proof -roll the <br />prepared base in the presence of the Inspector. The County may, as it deems necessary, <br />direct the Contractor to correct areas of weakness and excess moisture in the base by <br />scarifying, aerating, and reworking shore sessions to the full depth of the layer. If, after an <br />area has been reworked and recompacted, it remains soft or does not attain the required <br />density, the County may direct the Contractor to remove the material and replace it with <br />Granular Base Material meeting the requirements of these specifications. <br />5. Basis of Payment <br />a. Mobilization for Reclaiming: No payment for mobilization shall be due for returning the <br />equipment to the site when it has been removed and returned for the Contractor's own <br />purposes or because of breakdowns and repairs, weather delays, labor problems, accidents, <br />or the like, or when work has been resumed after being stopped by the County because of <br />unsatisfactory materials, equipment, or performance. Payment for Mobilization shall be <br />Lump Sum for the project. <br />b. Reclaimed Asphalt Base: In place and accepted, shall be paid for at the contract unit price <br />per square meter or square yard, as indicated in the Bid Sheet. The area of work for the <br />purpose of payment shall be the overall length of each reclaimed lane times the specified <br />total base width for the lane. The total base width shall include the widening width, if any, <br />in which the reclaimer is to be used to blend new base material with the pulverized layers. <br />Payment under this item shall be full compensation for all work included in or incidental to <br />the reclaiming operation, for the grading, shaping, and compacting of the Reclaimed Asphalt <br />Base, for the mix design study, for furnishing, delivering, and applying water, for applying <br />Division 2 — Technical Provisions - 01025-21 <br />F:\Public Works\ENGINEERING DIVISION PROJECTS\1639 69th Street 66th Avenue to US -1 Resurfacing (SCOP)\1-Admin\Bids\Bid Documents - Advertisement\DIV <br />2—TECHNICAL PROVISIONS - IRC-1639.docx <br />
