• Abstract:
  This report details the Phase II analysis of the life cycle and economic efficiency of inlaid tape ; and thermoplastic. Waterborne paint was included as a non-durable for comparison purposes ; only. In order to find the most economical product for specific traffic and weather conditions, ; the project examined the relationship between the pavement marking materials’ retroreflectivity ; and input variables. For three to four years, retroreflectivity data was collected from six ; locations in the state of Maryland. The sites were selected based on the amount of traffic and ; snowfall they received. Phase I of this study was done with one year of data, but that data ; collection period could not provide reasonable and reliable estimates of future retroreflectivity. ; As hoped, a two-year extension of the data collection period produced better estimates. The ; results of this research show that snowfall is a major factor in the deterioration of the ; retroreflectivity. The life cycle of each material was estimated under different conditions, and ; the installation cost of each material was estimated for the economic efficiency analysis. The ; results suggested that specific materials should be applied for specific weather and traffic ; conditions. Although inlaid tape’s estimated life cycle was longer than thermoplastic’s, ; thermoplastic’s lower cost made it the more economical material for all conditions.
