NIGP 74531: Bitumens, Bulk (Oil and Tar)

NIGP 74531 Bitumens, Bulk (Oil And Tar), an Item code, covers hot-mix asphalt and bituminous concrete supplied in bulk for highway pavement repair, overlay, and rehabilitation work across state departments, county transportation agencies, and regional transit authorities. State and local governments procure bituminous materials as components of larger roadway infrastructure projects—partial depth recycling operations, pavement overlays, parking area resurfacing, and pothole patching across state highway systems and local road networks. Recent solicitations show concrete demand: Santa Clara County's Central Expressway Pavement Rehabilitation Project (ITB ITBRDAFY260694, due May 21, 2026) specified hot mix asphalt overlay as part of comprehensive pavement repair work between Bowers Avenue and Scott Boulevard; Caltrans District 32 (IFB 32A0724, due August 4, 2026) required four inches of hot mix asphalt at 95 percent compaction for parking area repaving at its Equipment Shop 5 facility in San Luis Obispo; and Maryland Department of Transportation (solicitation 27-068, due May 8, 2026) solicited bulk bituminous concrete patching material for statewide highway maintenance. Issuing bodies span state transportation departments, county road agencies, sanitation districts seeking sewer infrastructure improvements with bitumen-related work, and municipal facilities management. Issuing agencies include California (Caltrans), Maryland Department of Transportation, Santa Clara County, and Texas Health and Human Services Commission (roof repair specification at the San Antonio Texas Center for Infectious Disease facility included bitumen components).

Recent activity concentrates in California and the Southwest, with secondary procurement in Maryland and the Upper Midwest. Santa Clara County appears twice in recent postings (May and September 2026 ITBs), indicating sustained regional demand for pavement rehabilitation. The Illinois Department of Transportation awarded a bituminous mix contract to Christ Bros under an economic adjustment clause modification (posted August 14, 2026), signaling active maintenance of existing supplier relationships in that state. Most current opportunities treat bituminous materials as line items within larger design-bid-build infrastructure projects rather than standalone material purchases, with response dates spanning May through September 2026 across multiple jurisdictions.
