NIGP 74586: Seal Coating

NIGP 74586 Seal Coating, an Item code, encompasses pavement preservation work that state and local governments procure to extend the life of asphalt and concrete surfaces through fog sealing, micro surfacing, slurry seal application, crack filling, and associated pavement marking and striping. Recent solicitations show municipalities and state departments contracting for fog seal application on parking lots and roadways, micro surfacing and slurry seal on street networks, crack sealing and rejuvenation at airports, and comprehensive parking lot rehabilitation combining multiple preservation techniques. The issuing-body mix spans state departments (Michigan Department of Technology, Management and Budget; Michigan Department of Operations and Support Services), counties (Williamson County Texas; Santa Clara County California; Wayne County Georgia; Barrow County Georgia; Tulare County California), cities (Jackson Michigan; Bend Oregon; Pembroke Pines Florida), school districts (Lawton Community Schools Michigan), and special-purpose districts (Wayne County Airport Authority). State facilities administration offices and county transportation or facilities divisions appear regularly across recent postings.
