ABSTRACT:
The method of making cast barrier structures consisting of the steps of, securing a plurality of form plates in a longitudinally spaced array over a supporting surface with the major plane of each form plate oriented substantially vertically and transversely to the length of the array, positioning side panels longitudinally alongside the form plates on opposite sides thereof and extending the length of the array, the side panels having upper and lower longitudinally extending edges with the lower edges seated on the underlying supporting surface and having irregularities on the inside surface which faces the form plates, fixedly securing the side panels to the form plates to form with the form plates and underlying surface an open-topped hollow assembly, and pouring a solidifiable plastic material downward through the open top of the hollow assembly to completely fill the interior thereof and integrally bond together the form plates and the side panels and the plastic material when the latter solidifies.
