| 摘要 |
The disclosure describes an improved tape material for use on a roadway pavement to form a traffic regulating strip or other sign thereon. The new material has a twin-layer structure including a lower relatively thin support layer and an upper principal thicker layer formed of a composition having a high internal molecular cohesion and having hard crystalline particles and light-reflecting particles embedded therein at various levels, the particles having portions which emerge above the upper face of the material to impart good anti-skid characteristics and nighttime visibility thereto, these properties being maintained as the material is progressively worn by the traffic due to progressive emergence of more deeply embedded particles. |
