摘要： A pavement marker having improved daytime visibility comprises a transparent fluorescent top portion having a top surface and a front edge. Light received by the top surface of the top portion results in light being directed internally through the top portion and emitted from the front edge, thereby providing a daytime signal to drivers of oncoming vehicles. In an alternative embodiment, the top portion can comprise a polymer having in its backbone moieties that either absorb U.V. light or that are capable of undergoing rearrangement to moieties that absorb U.V. light, to provide greater fluorescent durability. The polymer can be present either within the fluorescent top portion or as a U.V. light screening layer on top of the top portion.

摘要： A snowplowable pavement marker includes a frame member having primary spaced keel members with ramp surfaces which have upwardly inclined contours beginning at a forward end portion of each keel member and extending at a first acute angle, then transitioning to a second portion having a second acute angle which is greater than the first angle. Further, the frame member includes an auxiliary keel member having ramp surfaces disposed between the primary keel members and having the same contour as the primary ramp surfaces. The auxiliary keel member ramp surfaces extend inwardly of the frame member to a point proximate the marker's reflector and serve to prevent damage by a snowplow blade set at a wide angle to the direction of blade travel. Advantageously, the contour of ramp surfaces permits a higher frame member installation above the pavement and allows for greater exposure of the reflector.

摘要： A pavement marker having improved daytime visibility comprises a transparent fluorescent top portion having smooth flat parallel top and bottom surfaces with a front edge therebetween and air interfacing most of the bottom surface. Light received by the smooth flat top surface of the top portion is directed internally through the top portion and emitted from the front edge, to provide a visible signal to drivers of oncoming vehicles.

摘要： A pavement marker comprising a base member and a signal device for sending a light signal to a driver of an oncoming vehicle further includes a longitudinally extending tire directing hood member that directs tire contact away from the upper edge, upper portion, and upper generally corner portions of the signal device front face, while allowing tire contact with the lower portion of the signal device front face. The signal device front face is at a predetermined recess depth in said pavement marker, and is at a predetermined angle with respect to the roadway surface. The marker can be either a snowplowable marker or a sun country marker. The signal device optionally can be mounted on a base member by a mechanical interlock. Optional drainage channels can be provided in the base member to allow drainage of fluid from in front of the lower portion of the signal device.

摘要： 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.
摘要翻译： 用玻璃纤维增强的盆式外壳式路面标志，其形式为位于标记底部附近的玻璃纤维丝束的形式，或以分布在整个填充材料中的切碎的玻璃纤维束的形式。 垫子可以抵抗靠近标记底部的扭转或弯曲应力。 填充材料中的短切股线在整个壳体内部的填充物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中产生的裂纹数量，以防止发展出的任何裂纹的扩展，以防止标记物过早分解，并增加平均标记寿命。 支撑垫和切碎的玻璃纤维束可以一起使用在单个标记中。
