ABSTRACT:
A potted shell style pavement marker reinforced with fiberglass in the form of a mat of fiberglass strands located near the bottom of the marker or in the form of chopped fiberglass strands distributed throughout the fill material. The mat provides support against torsional or bending stresses near the bottom of the marker. The chopped strands in the fill material provide three-dimensional support throughout the height and depth of the fill in the interior of the housing. Both means of support are expected to reduce the number of cracks that develop in the fill, to prevent the expansion of any cracks which do develop, to prevent premature disintegration of the marker, and to increase average marker life. The supporting mat and the chopped fiberglass strands can be used together in a single marker.
