NIGP Item 74508 Asphalt, Emulsified encompasses the supply and delivery of emulsified asphalt products for pavement preservation, chip seal, slurry seal, and resurfacing applications across state and local transportation networks. State and local governments procure this commodity through competitive RFQs, RFBs, ITBs, and IFBs as a materials supply line item supporting road maintenance, reconstruction, and preventive pavement treatment programs, with purchasing patterns reflecting seasonal demand tied to construction and preservation seasons.

Issuing bodies span state departments of transportation, counties, cities, and special-purpose authorities. The State of Maine Department of Transportation, City of Palo Alto, City of San Antonio, Kenosha County (Wisconsin), Collin County and Hunt County (Texas), Solano County (California), and Winnebago County (Wisconsin) have posted recent solicitations under this code. County road departments and municipal public works divisions dominate the buyer base, with school districts and airport authorities entering the market for facility-scale paving projects. Representative recent opportunities include the City of Palo Alto Utilities Department RFQ for hot mix asphalt and coldmix cutback material on a three-year blanket purchase order with seven line items ranging from 200 to 2,200 tons annually (response deadline April 8, 2026); Collin County IFB for eleven liquid asphalt product types (CRS, CSS, MC, RC grades) with estimated annual contract value of $100,000 (bids due July 16, 2026); the State of Maine Department of Transportation RFQ for 354,011 gallons of MS-4 emulsified asphalt for pug mill operations at five delivery locations (quotations due March 5, 2026); the County of Solano IFB for 650 tons of polymer-modified rejuvenating emulsions (PMRE) asphalt emulsion oil with local-vendor preference applying (bids due July 7, 2026); and Winnebago County RFB for HFRS-2 emulsion oil transport and application across three county highway locations totaling 113,400 gallons (bids due February 26, 2026). Geographic activity concentrates in Texas (Collin County, Hunt County), California (Palo Alto, Solano County, Santa Clara County), the Upper Midwest (Maine, Wisconsin, Kenosha County), and scattered Georgia county road departments. The code reflects routine, recurring procurement across transportation agencies with firm fixed pricing, delivery-within-48-hours responsiveness expectations, and escalation provisions tied to Producer Price Index or cost-of-goods adjustments at contract renewal.
