NIGP 74587: Stabilized Base, Asphaltic

NIGP 74587 Stabilized Base, Asphaltic is an Item code describing the supply and placement of asphaltic stabilized base materials used in road and pavement reconstruction projects across state and local jurisdictions. State and local governments procure this material as part of broader pavement rehabilitation and new-construction initiatives—specifically, the prepared aggregate sub-base and hot-mix asphalt overlays that underpin durable road surfaces. Recent solicitations show demand for asphaltic base in milling-and-resurfacing programs, trail reconstruction, and pavement rehabilitation spanning multiple lane miles of roadway at varying depths and specifications (typically 3 to 6 inches of prepared aggregate base topped with asphalt concrete).

Issuing bodies include county transportation and public works departments (Santa Clara County, Pinellas County, Orange County), municipal transit authorities (Hartsfield-Jackson Atlanta International Airport Department of Aviation), and school and community college districts (San Jacinto Community College District). County governments dominate recent activity, with Pinellas County, Florida alone posting five separate fiscal 2027 pavement preservation packages (Packages 1 through 4 and an infrastructure repair work order contract) totaling over 146 lane miles and ranging from $6.45 million to $20 million in engineer's estimates. Santa Clara County has posted two major pavement contracts: Pavement Installation and Repair Services (ITB-PRC-FY27-0066, $2.5 million, due August 31, 2026) and Vasona Lake County Park East Trail Reconstruction (ITB-PRC-FY270091, due October 7, 2026, prevailing-wage public work). Orange County, Florida's Asphalt Milling and Resurfacing with Friction Course and Asphalt Berms project (Y26-182, estimated $125.6 million, due May 21, 2026) represents the largest single recent opportunity. Hartsfield-Jackson Atlanta International Airport's airfield repairs contract (PE66062NONST2026000000419, due June 26, 2026) and San Jacinto Community College District's South Campus FY26 Phased Pavement Repair (CSP #26-14, approximately $1.2 million, due May 21, 2026) round out recent activity. California and Florida account for the bulk of posted opportunities; Georgia, Texas, and additional jurisdictions represent secondary geographic spread. Two-step qualification and bid processes predominate, with SBE or MBE participation goals (typically 7 to 12 percent) required on most large county contracts, and prevailing-wage requirements on public-works designations. Fuel-price adjustments are generally prohibited; unit prices typically remain firm through project completion.
