Abstract
A system for dispensing a fast curing epoxy traffic marking composition to a transportation corridor includes a plurality of bins positioned on a transportation corridor marking dispensing apparatus. A first bin contains an epoxy coating which is applied by the dispensing apparatus on a transportation corridor. A second bin contains at least one curing agent which is coated on a carrier such as glass beads or porous silica. These carriers are dropped onto the epoxy coating by the dispensing apparatus and promote rapid curing of the top layer of the epoxy coating while the bottom layer is given additional time to adhere to the roadway surface. This enables the application contractor to open a marked roadway in a quicker manner with less motorist disruption. An optional third bin contains retroreflective beads which are applied to the epoxy coating by the dispenser apparatus to improve visibility of the line marking.
