Roadway barrier components formed using a system for recycling wet concrete and means for assembling multiple components into a continuous safety barrier wall

Abstract

A wet concrete recycling system for mixing trucks returning to the cement plant throughout the workday. “Residual-collection” molds, kept on-hand at the plant, are filled with any excess wet concrete present in the returning trucks. The molds are configured to form finished components such as roadway barrier sections (i.e. jersey walls), and the like. The finished components are low in cost due to the use of recycled wet concrete, inexpensive reinforcing materials, and handles/assembly elements fabricated from other recycled materials. The finished components may be sold or leased to customers, thereby converting costs typically associated with traditional residual concrete disposal techniques into supplemental income streams. The finished components may be assembled into continuous roadway safety barrier walls. All structures assembled from two or more of the finished components are inexpensive due to the low cost of the individual components, easily constructed, and may be permanent or temporary in nature.
