§ 14.06.210. Road construction standards—Paving specifications.

A.

Description. The RSA board will only certify roads containing asphalt concrete pavement on a prepared base if designed and stamped by a licensed civil engineer. The work under this section consists of the performance of all work required for the construction of asphalt concrete pavement on a prepared base (as shown in the Paved Road Typical Section drawing and associated Paved Road Table). Current editions of "Standard Specifications for Highway Construction," as adopted by the Alaska Department of Transportation and Public Facilities and the "Standard Specifications for Streets, Drainage, and Utilities," as adopted by the Municipality of Anchorage will be the references used for asphalt concrete paving.

B.

Material and testing. The RSA requires the asphalt pavement mix design be submitted and stamped by an Alaska licensed civil engineer or prepared and approved by the Alaska Department of Transportation. Process quality control records for aggregate shall be submitted with the asphalt pavement mix design. The project engineer must provide a certified as-built drawing or a detailed report certifying that the road has been constructed to RSA standards. This report must include photos, sieve analysis of materials used, field inspection reports, compaction test results, and other inclusions the RSA may request. The asphalt required by these specifications shall conform to the requirements of The Asphalt Institute for the type and grade and shall comply with ADOT/PF specifications used in the area. Crushed aggregate based coarse, D-1, shall comply with ADOT/PF specifications.

C.

Two-foot compacted shoulders are required.

D.

The prepared base shall, at a minimum, meet the standards for a Category III road. Inspection of the subgrade by the design engineer is required prior to paving.

E.

The contractor shall submit a certified analysis of the asphalt to the RSA for review and approval by the RSA director. The RSA reserves the right to make check tests of the asphalt at the project site, and, if the asphalt is not in accordance with the certified analysis, the road will be rejected for certification.

F.

The contractor or developer, at their own expense, will be required to perform field tests measuring aggregate gradation and fracture, asphalt content, and compaction. Test results shall be in conformance with pavement mix design requirements and shall be stamped by an Alaska licensed civil engineer.

G.

Other specifications. The RSA will use the current editions of "Standard Specifications for Highway Construction," as adopted by the Alaska Department of Transportation and Public Facilities and the "Standard Specifications for Streets, Drainage, and Utilities," as adopted by the Municipality of Anchorage to address seal coat, prime coat, paving geotextile, recycled asphalt paving, and other specifications required to assure the RSA the road meets all quality control measures.
