UNSPSC 22101629: Aggregate dryer

A cylindrical drying device used for drying and heating aggregates which are provided to the mixer of an asphalt mixing plant. It is composed of stationary type and movable types.

UNSPSC 22101629 Aggregate dryer, a Commodity code, does not align with the recent state and local opportunities tagged under it. The three recent solicitations from Santa Clara County are for comprehensive pavement rehabilitation and road infrastructure projects — including partial-depth recycling, hot mix asphalt overlays, concrete curb and gutter work, guardrail replacement, bridge construction, and traffic signal installation — none of which center on aggregate drying equipment or related machinery. The mismatch suggests either a tagging error in the source data or that aggregate dryers are a minor incidental component within larger infrastructure procurement scopes where the primary code assignment reflects the dominant work scope rather than all embedded equipment needs.

Santa Clara County is the sole issuing body in the recent-opportunities block, having posted three competitive ITB solicitations in the first quarter of 2026: the Red Fox Creek Bridge #37C0172 Replacement Project (due March 5, 2026), the Expressway Guardrail Replacement and Safety Barrier Improvements project (due April 23, 2026 with a mandatory pre-bid conference on April 14, 2026), and the Central Expressway Pavement Rehabilitation Project Between Bowers Avenue and Scott Boulevard (due May 21, 2026). All three required sealed physical bid submission to the County Government Center in San Jose; electronic bids were not accepted. Given the limited activity visible under this commodity code and its apparent misalignment with actual procurement scope, business development professionals should verify the relevant commodity and family codes for road construction and material-handling equipment before allocating pursuit resources to this category.
