Abstract: A potted shell style pavement marker (20) reinforced with fiberglass in the form of a mat of fiberglass strands (28) located near the bottom (30) of the marker or in the form of chopped fiberglass strands (32) distributed throughout the fill material (26). The mat (28) provides support against torsional or bending stresses near the bottom of the marker (30). The chopped strands (32) in the fill material (26) provide three-dimensional support throughout the height and depth of the fill in the interior of the housing (22). Both means of support are expected to reduce the number of cracks that develop in the fill (26), 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 (28) and the chopped fiberglass strands (32) can be used together in a single marker.

Abstract translation: 一种用玻璃纤维增​​强的盆状壳型路面标记（20），其为位于标记的底部（30）附近的玻璃纤维束（28）的形式或以分布在整个填充材料中的短切玻璃纤维束（32）的形式 （26）。 垫（28）提供抵抗标记（30）底部附近的扭转或弯曲应力的支撑。 填充材料（26）中的短切股（32）在整个壳体（22）的内部的整个高度和深度处提供三维支撑。 预期两种支撑手段可以减少在填充物（26）中产生的裂纹数量，以防止发生任何裂纹的膨胀，以防止标记物过早分解，并增加平均标记寿命。 支撑垫（28）和短切玻璃纤维束（32）可以一起用于单个标记。
