Abstract:In UTCA projects 01465 and 04405, the retroreflectivities and the life cycle costs were measured and compared for standard Alabama Department of Transportation (ALDOT) thermoplastic edge
stripes that contained only one size of retroreflective beads. This project will perform a
quantitative assessment of the wet and dry retroreflectivities and the life cycle costs of
thermoplastic edge lines containing two sizes of beads both in the intermix beads and the beads
applied to the surface. Those values will be compared to the data already amassed for the
standard edge lines.
