Abstract: A pavement marker for a roadway surface includes a lower base portion and a retro-reflective lens mounted on the base portion at an angle to it. A photopolymerizable clear acrylic protective hard coat is deposited over and integrally formed with the front face of the lens for resisting abrasion of the lens and reducing the loss of optical efficiency resulting from such abrasion. The pavement marker also includes a frame of generally arcuate cross-section formed about an edge of the hard coat potentially susceptible to peeling from impact of vehicle tires against the hard coat. The frame is preferably formed as a bead raised from the face of the marker, and the bead includes a sharp interior edge lying generally perpendicular to the lens, adjacent the edge of the hard coat.

Abstract translation: 用于道路表面的路面标记包括下基部和与其成一定角度安装在基部上的回射透镜。 可光聚合的透明丙烯酸保护性硬涂层沉积在透镜的前表面上并与透镜的前表面一体形成，以抵抗透镜的磨损并减少由于这种磨损引起的光学效率的损失。 路面标记还包括围绕硬涂层的边缘形成的大致弓形横截面的框架，其潜在地易于从车辆轮胎撞击硬涂层的冲击剥离。 框架优选地形成为从标记物的表面凸起的珠粒，并且珠子包括大致垂直于透镜的尖锐内部边缘，邻近硬涂层的边缘。

Abstract: A pavement marker for roadway surface including a housing 12 having a lower base portion 14 and at least one wall 18 extending substantially upwardly from the base portion 14. A retroreflective lens 20 is mounted on the wall 18 and has a front surface 22 facing away from the wall 18. A photopolymerizable clear acrylic protective hard coat is deposited over the front face of the lens for resisting abrasion of the lens and reducing the loss of optical efficiency resulting from such abrasion.A method of making the pavement marker includes the steps of forming the lens 20 having the front face 22, coating the front face 22 of the lens 20 with a photopolymerizable acrylic composition, irradiating the coating with ultraviolet or electron beam irradiation to cure the acrylic composition to an abrasion resistant coating 24, and mounting the lens 20 in the housing 12 to dispose the coated front face 22 away from the housing 12.

Abstract: A reflective pavement marker includes a shell having a top wall, a side wall extending from an end of the top wall, and reflective end walls extending from an other end of said top wall, wherein the shell forms an interior cavity. The reflective pavement marker also includes a reflective portion integral with the reflective end wall, a reflective coating covering the reflective portion and a bonding coating covering at least the reflective portion. The reflective pavement marker further includes a filler material within the interior cavity of the shell.
