    • A pavement marking 10 includes a base sheet 12, a barrier layer 30, a layer 32 of bonding material, a multitude of optical elements 34, and skid-resistant particles 36. The base sheet 12 contains rubber and fillers and has a number of protuberances 14 projecting from its front side 28. Valleys 16 are disposed between the protuberances 14. The barrier layer 30 is disposed on the front side 28 at least in valleys 16 and preferably over protuberances 14. The layer 32 of bonding material is disposed predominantly on protuberances 14 and in this position secures the optical elements 34 and skid-resistant particles 36 to the protuberances 14 but not to the valleys 16. The coverage of the front side 28 of base sheet 12 with barrier layer 30 and bonding material 32 prevents the fillers in the base sheet 12 from becoming present on the top surface of the pavement marking 10 and thereby preserves the intended color of the marking 10.
    • 路面标记10包括基片12,阻挡层30,接合材料层32,多个光学元件34和防滑粒子36.基片12包含橡胶和填料,并且具有多个突起 凹槽16设置在突出部14之间。阻挡层30至少在谷部16中设置在前侧28上,优选地设置在突出部14上。接合材料层32主要设置在突起部 并且在该位置中,光学元件34和防滑粒子36固定到突起14而不固定到谷部16。具有阻挡层30和接合材料32的基片12的前侧28的覆盖防止了填充物 基片12变得存在于路面标记10的顶面上,从而保持标记10的预期颜色。
