TerraTec Industries, Inc. has developed the highly innovative AggreScreedTM – a bulldozer attachment used to rapidly lay gravel for roads, runways, parking lots, etc. without the use of stakes and does so in a single pass while minimizing gravel segregation and breakage. Attachable to virtually any straight-blade bulldozer (125-250 horsepower recommended) the 16-foot AggreScreed blade adjusts to 24 feet in two-foot increments. It’s capable of laying gravel at depths from zero to 15 inches and can create up to a three-and-a-half percent crown. The AggreScreed laid over 18,000 tons of aggregate in a single day with a two-man crew.
