About this file
This document is a technical specification for asphalt paving for the Department of Veterans Affairs, specifically for resurfacing roadways and a patient parking lot at the Albany VAMC. The specification details comprehensive requirements for asphalt pavement construction, including aggregate base course, asphalt surface course, and crack sealing, with strict adherence to New York State Department of Transportation (NYSDOT) standards. Key technical requirements include precise temperature controls for asphalt mixing (143-160°C), specific aggregate compositions, roller compaction procedures, and surface smoothness tolerances of 3mm in 1.8m.
The specification covers multiple technical aspects such as subgrade preparation, base course construction, asphaltic concrete placement, and crack sealing, with detailed instructions for material selection, mixing, spreading, rolling, and finishing. Materials must meet NYSDOT specifications, with asphalt cement of penetration grade 50/60, prime coat of MC-250, and tack coat of SS-1H. The work involves establishing precise alignments, grades, and cross-sections, with strict quality control measures including temperature monitoring, compaction requirements, and surface finish standards. The project is associated with Solicitation Number 36C24225B0025 for the Veterans Health Administration's Veterans Integrated Service Network 2.
