Reclaiming. The Contractor shall pulverize the existing pavement in multiple passes of the reclaimer, applying sufficient mechanical effort to reduce the fragments to a maximum size of 75 mm (3 inches). In this process the pulverized material shall be combined uniformly with the base and subgrade to a depth which the Public Works/Engineering Department may specify. Following the reclaimer, a roller shall be applied to compact the blended material sufficiently to support traffic temporarily. The depth of material to be compacted shall not exceed .150 mm (6 in). The Public Works/Engineering Department may require removal of up to 50 mm (2 in) of pulverized material prior to addition of the stabilizing agent. When the pulverizing and mixing step is complete, the material shall be graded, watered, remixed, shaped, and compacted as necessary to establish proper grade and uniform thickness and to support traffic temporarily. Water shall be applied if necessary to obtain uniform moisture content as the Public Works/Engineering Department may specify. The Contractor shall apply additional water at frequent intervals as needed to suppress dust, preserve the surface, and maintain the specified moisture content. The stabilizing agent shall then be applied and mixed to the depth specified by the Public Works/Engineering Department, and grading and compaction of the combined base material shall proceed immediately behind the mixing of the stabilizing agent. Before final grading and the addition of the emulsion, when directed by the Public Works/Engineering Department, the Contractor shall adjust the cross-slope, super elevation, and profile grade by adding granular base material in areas the Public Works/Engineering Department may designate.
