Estimating the Lifecycle of Pavement Markings on Primary and Secondary Roads in South Carolina
The absence of systematic procedures and standardized methods to quantitatively evaluate pavement marking materials on South Carolina's primary and secondary roads has made it difficult for the South Carolina Department of Transportation (SCDOT) to track performance and determine lifecycle duration of pavement markings from installation to eventual restriping applications. In 2008, SCDOT issued a problem statement for research supporting development of guidelines for pavement marking applications. Objectives of this research focused on determination of evidence-based guidelines and recommendations to support pavement marking best practices for consistent implementation across the state. Through the use of a data-driven research methodology and measured retroreflectivity values systematically collected at selected representative control sites, lifecycle models and degradation models were determined for waterborne, high-build and thermoplastic pavement marking applications for the States primary and secondary road network. A comparison of marking lifecycles was performed and recommendations regarding material selection for typical applications were developed. This report summarizes findings of a three-year research project and includes a literature search, discussion of data collection and analysis, development of retroreflectivity degradation models, comparison of marking materials, and identification of recommended guidelines.
