RETROREFLECTIVE PAVEMENT MARKING WITH IMPROVE PERFORMANCE IN WET NIGHT CONDITIONS

摘要

A preformed thermoplastic pavement marking material with embedded large retroreflective beads resulting in a minimum retroreflectance of 100 mcd/m2/lx in standard conditions of wetness is described. The current composition includes these retroflective beads where more than 70 % of the beads have diameters greater than 2mm. The beads may be applied during manufacturing or installed by applying the retroreflective beads to a hot or un-cured matrix material composition.
