COMPARATIVE STUDY OF GLASS BEAD USAGE IN PAVEMENT MARKING REFLECTORIZATION
Prior research and field experience with a variety of pavement marking materials and glass beads for marking reflectorization are examined. The use of large glass beads to enhance the wet-night reflectivities of pavement markings was investigated, together with binder characteristics, to provide effective service life estimates, optimum bead-binder combinations, and cost-effectiveness comparisons. A literature review and a state-of-the-art survey conducted in southern states revealed that the cost difference between large and standard glass beads was low relative to the amount of increased wet-night visibility offered by large glass beads. However it is not known with certainty how the high pavement temperatures and climatic conditions indigenous to the South will affect the service lives of markings with large glass beads. Field testing of large glass beads on roads with a relatively large number of wet-night accidents could enable determination of the effective service lives of bead-binder-pavement type combinations as well as expected accident reduction benefits.
