Florida's Wet Weather Demonstration Project
The Florida Department of Transportation (FDOT) established a wet-weather pavement marking demonstration project with goals to gather performance data, evaluate various wet-weather marking systems, and develop a measurement protocol for measuring retroreflectivity under continuous wetting conditions. FDOT coordinated the installation of a variety of specially designed pavement marking systems along a section of Interstate Highway 10, just west of Tallahassee, Florida. Being a test deck designed specifically for wet-nighttime performance, most of the markings had special characteristics to provide enhanced wet-nighttime performance. The standard marking used as a control was the standard FDOT application of double drop optics (both optics having 1.5 refractive indices) on non-profiled thermoplastic. Several continuous wetting handheld retroreflectivity measurement protocols were tested against charged coupled device (CCD) based luminance measurements. While the overall correlations were strong, it was noted that the control pavement marking system (without specially designed wet-nighttime performance characteristics) suffered from inequitable and unrepresentative measurement results under the highest continuous wetting rates. A complete set of guidelines is provided for the measurement protocol, including detailed drawings and a parts list for the equipment needed to implement the recommended protocol.
