Retroreflecting road marking system comprising a coating layer which is composed of a binder, glass beads, one or more pigments, and fillers, on which immediately after its application and prior to its complete cooling, drying and/or curing glass beads have been introduced, the coating layer comprising a composition composed of: 30-70 wt. % of glass beads having a particle size distribution in the range of 0.8 to 3.5 mm, 3-30 wt. % of TiO2, 5-40 wt. % of fillers and/or aggregate, as well as 10-40 wt. % of binder, and the particle size distribution of the glass beads introduced immediately after application being in the range of 100 to 600 mum, preferably in the range of 100 to 300 mum. Through the effect of traffic the retroreflecting road marking system according to the invention attains good retroreflecting properties soon after application also in the wet state and loses these far less quickly even after busy traffic. |
