Re-establishing of the reflectiveness of a surface marking material with reflective beads

摘要

A method and a device is disclosed for re-establishing the reflectiveness of a surface marking material with reflective beads therein, such as a road surface marking material, as well as the use of compositions to perform the re-establishment.;The preferred embodiment disclosed comprises the steps to dissolve the top layer of the matrix material in which the beads are contained by means of a liquid and mechanical affecting of the material, followed by a water flushing to remove the remains of said first liquid material and the resolved matrix material. The uncovered beads are then polished by applying a second liquid to emulsify the remaining matrix material left on the beads and polish by means of rotation brushes, where after the emulsion is removed by suction.
