8-1-26: CONSTRUCTION METHODS FOR PAVED STREET RESTORATION:
   A.   Strict Rules For Compaction; Penalty: The bottom twelve inches (12") and the top eighteen inches (18") of the subgrade backfill shall be the same type of backfill material specified in section 8-1-25 of this chapter. The excavated material may be used for the remainder of the backfill, provided that no materials greater than six inches (6") in diameter shall be used for backfill. The material shall be deposited in layers not exceeding twelve inches (12") in thickness prior to compacting. Each layer shall be compacted with suitable mechanical tamping equipment. It shall be compacted sufficiently to obtain a field density which is at least ninety five percent (95%) of theoretical density as determined by AASHTO method T-147. The permittee shall be required to obtain geotechnical test inspections by a certified technician and reports reviewed by a professional engineer. Public works shall require all permittees to contact public works twenty four (24) hours in advance of commencement of backfill operations to allow the department time to arrange for additional inspection. Failure to obtain proper inspections or contact the department will result in forfeiture of the street cut bond monies. The cost of compaction tests will be paid by the town. The costs of retests will be paid by the permittee. Compaction methods not authorized herein must be approved by public works prior to their use by the permittee.
   B.   Longitudinal Cuts; Special Methods: All longitudinal cuts that are located four feet (4') or more into the paved area and exceeding fifteen feet (15') in length shall be patched and the entire street overlaid with asphaltic concrete a minimum of one and one-half inches (11/2") thick. This requirement shall not be applicable to cuts for the installation of structures that extend four feet (4') or more into the paved area, unless otherwise required by public works.
