Tire-Derived Aggregate (TDA) Grant Program

Overview

This competitive tire grant program provides opportunities to divert waste tires from landfills, prevent illegal tire dumping, and promote markets for recycled-content tire products. The Program provides assistance to civil engineers in solving a variety of engineering challenges using Tire-Derived Aggregate (TDA), which is produced from shredded tires, is lightweight, free-draining, and a less expensive alternative to conventional aggregates. Eligible Projects: Projects generally fall into one of five categories (see TDA Uses for more complete descriptions): Category 1: Mechanically Stabilized TDA (retaining walls). Category 2: Low Impact Development (storm water mitigation including storm water infiltration galleries). Category 3: Lightweight fill (slope stabilization, embankment...
