Abstract
A pavement marking wetting device provides consistent, even wetting to pavement markings for use in taking retroreflectivity measurements. The wetting device includes a nozzle which is connected to the tank of a water truck for fast, efficient wetting. The nozzle includes an air gap which creates a balancing of air pressure, thereby insuring consistent, even dispersion.
