NIGP 74501: Aggregate, Precoated

NIGP 74501 Aggregate, Precoated is an Item code describing precoated aggregate products—stone or mineral materials bound with bituminous binder—that state and local governments procure for asphalt paving, pavement preservation, and road construction. Recent solicitations show governments buying precoated aggregates in two primary forms: hot-mix asphaltic concrete (HMA) incorporating recycled asphalt pavement (RAP) and recycled asphalt shingles (RAS) for new or overlay paving, and frictional preservation treatments combining precoated aggregate with mastic or polymer-modified binders for surface treatments and crack relief. Collin County, Texas issued an IFB on June 23, 2026 (due July 16, 2026) for asphaltic concrete in multiple grades and mixes with estimated annual volumes of 50 to 20,000 tons per item and a $3 million estimated contract value, while the City of Dallas issued a two-year ID/IQ solicitation (posted February 19, 2026, due March 20, 2026) for precoated asphaltic preservation treatment and mastic with no minimum order quantities. Issuing bodies span counties (Collin, Dane, Barrow), cities (Dallas, Detroit, Arlington, Tucson, Gluckstadt), and special districts (Boulder County Parks and Open Space). Detroit's Department of Public Works and regional cooperative purchasing vehicles like the Berkshire Regional Group Purchasing Program (covering 32 Massachusetts municipalities) also procure aggregate materials including precoated asphalt products.

Geographic activity concentrates in Texas (Collin County, Dallas, Arlington), California (Santa Clara County), Florida (Broward County), Michigan (Detroit), and the upper Midwest (Wisconsin, Massachusetts), with secondary activity in Mississippi, Colorado, and Georgia. Recent representative solicitations include Collin County's Asphaltic Concrete IFB and Aggregate for Surface Treatments procurement (both June 2026, due July 16, 2026) with materials required in multiple zones throughout the county and pickup or delivery within 48 hours; the City of Dallas's Frictional Asphaltic Preservation Treatment ID/IQ (due March 20, 2026) requiring minimum 30 percent mineral solids and 10 percent polymer by weight with thirty-business-day delivery windows; the City of Detroit's Bituminous Aggregate Wearing Course RFQ (due June 29, 2026) for 3,000 tons with Detroit-based business equalization preferences; and Barrow County's road resurfacing projects incorporating recycled asphaltic concrete topping (February 2026 solicitations). Bidders typically must comply with state DOT specifications (TxDOT, FDOT, GDOT, MassDOT), provide recycled-material content documentation, meet insurance and bonding requirements, and demonstrate prior similar-project experience. Contracts generally run one to two years with renewal options, and awards often allow split awards or multiple vendors to serve geographic zones or material-type categories.
