Concrete Pavers

A concrete paver typically use a slipform process to pave roadways, first spreading fluid concrete placed on the grade with an auger, then removing excess material with a strike-off plate. Hydraulic vibrators consolidate the concrete, and tamper bars push the large aggregate below the surface. The paver's profiling plans then set the finished elevation and provide an initial finishing of the
