Abstract:This project examined the life cycle and economic efficiency of two pavement marking
materials — inlaid tape and thermoplastic — to find the most economical product for specific
traffic and weather conditions. Six locations in the state of Maryland were selected for data
collection based on the amount of traffic and snowfall they receive, and the data was collected
for one year. While one year of data yielded reliable and consistent results for a recent study of
the life cycle of waterborne paint, the regressions for the durable materials in this study were
unreliable and cannot be recommended. To ensure reliability and consistency in the estimation
of the retroreflectivity of inlaid tape and thermoplastic, we suggest that future studies include
more extensive data.
