UNSPSC 30121504: Bitumen

UNSPSC 30121504 Bitumen, a Commodity code, covers hot-mix asphalt, bulk bituminous concrete patching material, and related asphalt paving products that state and local governments purchase for highway resurfacing, parking lot repaving, pavement rehabilitation, and road maintenance programs. Recent solicitations show state departments of transportation, county highway divisions, sanitation districts, and county governments procuring these materials and services for capital improvement projects ranging from localized parking area resurfacing to multi-mile corridor pavement rehabilitation and pipe-bedding applications in sewer infrastructure work. The work typically bundles material supply with labor for installation, grading, compaction, and surface finishing, often incorporating ancillary scope such as curb installation, traffic signal work, and stormwater management that fall outside the bitumen commodity itself but are packaged within the same bid.

Geographic activity concentrates in California and extends into Maryland and Illinois. Representative recent solicitations include Santa Clara County's Central Expressway Pavement Rehabilitation Project between Bowers Avenue and Scott Boulevard (ITB ITBRDAFY260694, due May 21, 2026), which specified partial depth recycling and hot-mix asphalt overlay across 142 working days; Caltrans District 32's repaving of its Equipment Shop 5 parking area in San Luis Obispo (IFB 32A0724, due August 4, 2026, with a 3 percent Disabled Veteran Business Enterprise participation requirement and 25 percent Small Business participation goal); Maryland Department of Transportation's bulk bituminous concrete patching material procurement for statewide highway maintenance (solicitation 27-068, bid due May 8, 2026); and Illinois's FY25 Bit Mix Contract with Christ Bros., which was modified in August 2026 under an economic adjustment clause. Santa Clara County appears as a repeat buyer, issuing multiple pavement and infrastructure solicitations in the recent window. Prevailing wage, apprenticeship compliance, and set-aside or participation goals are standard requirements across these procurements.
