2.1 DESCRIPTION AND GENERAL REQUIREMENTS: In areas where granular base course has been placed as a previous stage of street, or road construction, the contractor shall blade, shape and compact the base course in conformance with the required dimensions, line, grade, and cross section to permit completion of the paving work. When directed by the Planning Commission, or its duly authorized representative, additional base course aggregate shall be provided or excess aggregate removed and disposed of, by the contractor, as to provide conformance with the required roadway section.
2.2 THICKNESS OF SURFACING REQUIRED FOR EXISTING GRANULAR BASE COURSES: The existing thickness of granular base comprises a portion of the required design thickness as specified in Section 4.4, Attachment B of these regulations.
The existing thickness of granular base must be divided by the appropriate conversion factor, contained in Table 4, for the inplace base type to determine the portion of the design thickness, the equivalent thickness, represented by the existing granular base course. The difference between the design thickness and the equivalent thickness is the thickness of surfacing that shall be required to be constructed over the existing granular base course. Composition and construction of the required surfacing shall meet all requirements herein specified.
