UNSPSC 30111802: Artificial aggregate

An aggregate made artificially by crushing rocks.

UNSPSC 30111802 Artificial aggregate (Commodity) encompasses raw and processed stone, sand, slag, recycled concrete, and cover materials that state and local governments procure for road base, pavement sub-base, winter maintenance, and infrastructure construction. Recent solicitations show consistent demand across transportation departments, cities, counties, and special districts for materials ranging from coarse crushed stone and recycled asphalt to fine sands and lightweight cover chips, supplied either loose at pickup locations or delivered to jobsites and stockpile yards. The issuing-body mix includes state departments of transportation (Utah, Oregon, Georgia), city and county public works departments (Detroit, Salt Lake City, Santa Clara County, Barrow County), regional cooperative purchasing programs (Berkshire Regional Group Purchasing Program covering 32 Massachusetts municipalities), and county parks and open space departments (Boulder County). Detroit's Office of Contracting and Procurement appears as a repeat buyer, issuing multiple RFQs in recent months for asphalt and aggregate materials totaling thousands of tons annually.

The code shows strong recent activity concentrated in the Mountain West and California. Utah Department of Transportation has issued at least five separate IFBs since mid-April 2026 for granular borrow, cover material, and road base, with volumes ranging from 1,500 to 12,255 tons and delivery deadlines through May 31, 2026. Salt Lake City and Barrow County, Georgia have solicited recycled concrete products through RFBs with response dates in March and May 2026. The City of Detroit issued RFQ 548310 on June 15, 2026 (due June 29, 2026) for 3,000 tons of bituminous aggregate wearing course with an equalization preference for Detroit-based certified businesses ranging from 1% to 5%, and an earlier RFQ 546989 (due June 5, 2026) restricted exclusively to Detroit-based certified contractors for approximately 11,000 tons of stone, sand, and slag. Santa Clara County and the Berkshire Regional Group Purchasing Program solicited larger infrastructure projects requiring aggregates as embedded materials. Oregon Department of Transportation issued RFCQ S7300000016528 on April 9, 2026 (due April 23, 2026) for 10,000 cubic yards of sanding rock production at Brooks Quarry. The Berkshire Regional Group Purchasing Program's cooperative procurement (posted April 19, 2026, due April 2, 2026 — an apparent posting error) covers aggregates and loam as part of a larger 20-category highway supplies package for 32 municipalities, with estimated aggregate values integrated into broader pavement and materials contracts. Geographic concentration appears in Utah (multiple UDOT regions), Michigan (Detroit), California (Santa Clara County), Massachusetts (Berkshire County), and scattered activity in Colorado, Georgia, Maryland, and Oregon.
