Description

ABSTRACT:
A concrete barrier having a plastic cladding that provides protection for the concrete against chemical deterioration. A cap assembly enables the barrier to be fitted with standard anchor sheets and made in standard jersey barrier forms. The cap assembly has a large radius so that anchor sheets can be easily bent and will fit snugly within the form to prevent wet concrete from leaking between the anchor sheet and the form. The invention can be used with all standard jersey barrier forms, both horizontal and upside-down type, for either full or half barriers.
