TerraTec Industries developed the AggreScreed, a bulldozer attachment designed to rapidly lay gravel (for roads, runways, parking lots, etc.) without the use of stakes in a single pass to minimize gravel segregation and breakage. Attachable to almost all straight-blade bulldozers (125-250 horsepower recommended) the 16-foot (4.9 m) AggreScreed blade adjusts to 24 feet (7.3 m) in two foot (0.6 m) increments. It’s capable of laying gravel at depths from zero to 15 inches (0 - 38 cm) and can create up to a 3.5 percent crown. The AggreScreed is also designed to reduce gravel lay down labor by up to 60% with precise material control. It can put down up to 18,000 tons of aggregate in a single day with a two-man crew.
