NIGP 75004: Ash, Fly and Bottom

NIGP 75004 Ash, Fly And Bottom is an Item code under which state and local governments procure materials and labor for pavement rehabilitation, roadway resurfacing, and related infrastructure improvements that incorporate recycled asphalt and concrete components. Recent solicitations show actual procurement focused on comprehensive pavement work including partial depth recycling, hot mix asphalt overlays, recycled asphaltic concrete resurfacing, Portland cement concrete curb and gutter installation, ADA access improvements, guardrail replacement, traffic control markings, and shoulder filling — work that directly consumes fly ash and bottom ash byproducts from power generation or recycling streams as pavement components and stabilization materials. The issuing bodies are county transportation departments and county public works offices managing rural and suburban roadway networks; Santa Clara County, California and Barrow County, Georgia appear as active recent buyers under this code.
