EVALUATION OF RETRO-REFLECTIVE BEADS IN AIRPORT PAVEMENT MARKINGS
This report identifies the results of a 1-year comparative evaluation on the use of retro-reflective glass beads in airport surface pavement markings. Class beads meeting Federal Specification TT-B-1325B, Type I and III were tested at three airports for retro-reflectivity, effects of runway friction, conspicuity, and durability. The three test airports were Atlantic City, Greater Pittsburgh, and Phoenix Sky Harbor International airports. Data from this study show the use of beaded materials in airport markings increased the conspicuity and quality of the airport markings. Also discovered in this evaluation was the friction enhancement gained from the incorporation of beads and silica additives into the paint materials. As a result of the findings of this study, certain modifications are recommended for the two existing specifications regarding airport pavement markings.
