NIGP 74587: Stabilized Base, Asphaltic

NIGP 74587 Stabilized Base, Asphaltic (Item) encompasses milling, resurfacing, and stabilization work on roadway pavements that state and local governments procure at significant scale across multiple jurisdictions. Recent solicitations show active demand for full-depth milling (typically 1.5 to 2 inches), placement of Superpave asphalt concrete overlays (ranging from SP 9.5 to SP 12.5 grades depending on arterial versus local roads), pavement markings, utility adjustments, and ancillary work such as inlet protection and traffic control. Counties and municipalities dominate the issuing-body mix, with Pinellas County, Florida emerging as a standout repeat buyer—the county has posted at least four separate pavement preservation packages in the past month (Packages 1, 3, and 4 with lane-mile totals ranging from 34.81 to 38.92 miles per package) plus an infrastructure repair work order contract for hurricane-season reconstruction. School districts, county transportation authorities, and municipal airport departments also procure under this code; the Department of Aviation at Hartsfield-Jackson Atlanta International Airport and Okaloosa County's Department of Transportation Services have each issued airfield pavement rehabilitation solicitations. Beyond resurfacing, the code captures material supply for patching and stabilization—Brazoria County, Texas has posted separate invitations for patching materials, stabilizing materials (hydrated lime, lime slurry, cement-stabilized sand and base), and surface courses (recycled asphaltic concrete and hot mix asphalt).

Activity concentrates heavily in Florida and Georgia, with significant additional work in California (Santa Clara County, the City of Fairburn, Hartsfield-Jackson in Georgia), Texas, and Colorado. Representative opportunities include Pinellas County's Fiscal Year 2027 Pavement Preservation Package 4 (ITB-C 26-0364, $6.75 million engineer's estimate including engineering and inspection, bids due July 21, 2026), Pinellas County's Package 3 (ITB-C 26-0363, $6.45 million, bids due August 11, 2026 step two, 7% SBE participation goal), Orange County, Florida's Asphalt Milling and Resurfacing with Friction Course and Asphalt Berms (Y26-182, $125.6 million estimated cost over 60 months with annual PPI-based escalation capped at 4%, bids due May 21, 2026), and Santa Clara County's Central Expressway Pavement Rehabilitation Project (ITB-RDA-FY26-0694, 142 working days, bids due May 21, 2026). All Florida and Georgia jurisdictions explicitly reference SBE participation goals ranging from 7% to 12%, FDOT or GDOT prequalification requirements, and compliance with state-specific prevailing wage and trench safety standards. Most solicitations use two-step qualification-and-bid processes with electronic submission through platforms such as OpenGov, and all require performance and payment bonds at or near 100% of contract value plus proposal or bid bonds at 5% to 10%.
