UNSPSC 11101701: Slag or ash

UNSPSC 11101701 Slag or ash, a Commodity code, represents materials sourced primarily for pavement rehabilitation and road construction projects. State and local governments buy recycled asphalt concrete (RAC), recycled asphaltic concrete, and related aggregate materials under this code, as evidenced by recent solicitations emphasizing partial depth recycling, hot mix asphalt overlays, and open-graded crack relief interlayers in roadway resurfacing work. County public works departments and transportation authorities are the primary issuing bodies, with emphasis on infrastructure rehabilitation rather than new construction.

Santa Clara County, California has issued two recent ITB notices for expressway pavement and guardrail projects (Central Expressway Pavement Rehabilitation Project, ITB ITBRDAFY260694, due May 21, 2026, and Expressway Guardrail Replacement and Safety Barrier Improvements, ITB ITBRDAFY260652, due April 23, 2026), both requiring removal and replacement of existing roadway materials as part of comprehensive rehabilitation scope.
