What's involved in producing slipformed median barriers? The scope of most barrier-wall projects requires a big investment in equipment and manpower, thorough job preparation and organization, and attention to base construction and reinforcing-steel placement. Once the site is carefully prepared, it's necessary to carefully choreograph the movements of work crews, ready mix trucks, and the paver. If a slipformer is to work properly, it needs a continuous supply of uniform concrete.
Each job has unique features. Walls can have various cross sections, range in height from 32 to more than 100 inches, and be asymmetric or superelevated. Accommodating these variations often requires experience and ingenuity.
