Industries is showing its innovative AggreScreed – a bulldozer attachment used for
rapid laying of gravel for applications including roads, runways and parking
lots. The AggreScreed allows gravel to be laid without the use of stakes and
does so in a single pass while minimizing gravel segregation and breakage, said
the company. AggreScreed is attachable to virtually any straight-blade
bulldozer and the 16foot (4.9m) blade adjusts to 24feet (7.3m) in 2foot (600mm increments).
It is capable of laying gravel at depths from zero to 15 inches (380mm) and can
create up to a 3.5% crown. The AggreScreed can reduce gravel-lay-down labor by
up to 60% with precise material control, said TerraTec Industries, and has
proven itself by putting down 18,000US tons (16,325tonnes) of aggregate in a
single day with a two-man crew.
