Understanding The Impact Of Bead Type On Paint And Thermoplastic Pavement Markings, Joshua D. Hollingsworth
Understanding The Impact Of Bead Type On Paint And Thermoplastic Pavement Markings, Joshua D. Hollingsworth
Theses and Dissertations
Each year the United States spends approximately two billion dollars maintaining pavement markings. In addition, an impending Federal policy establishing a minimum retro-reflectivity value for pavement markings has driven asset managers to develop performance models to effectively and efficiently manage these high quantity, low cost assets. Research over the past decade has sought to identify and understand the many factors influencing pavement marking degradation. Despite the fact that reflective glass beads are foundational to pavement marking retro-reflectivity, little research has specifically considered the impacts of bead type. The purpose of this study is to quantify the impact that bead type …
Maintenance Operations Degradation Of Airfield Pavement Markings, John C. Jaszkowiak
Maintenance Operations Degradation Of Airfield Pavement Markings, John C. Jaszkowiak
Theses and Dissertations
Pavement markings are an essential element in the navigational aids subsystem for any airfield. Most airfields still use waterborne paint as the primary marking material, although there are other materials in use on roadways that airfield managers could use to save time and money. An airfield experiences a host of maintenance operations that cause degradation of the pavement markings. Of particular concern are rubber removal operations, sweeping operations, and snowplowing operations. This research focuses on chemical rubber removal operations and sweeping operations. The study evaluates waterborne paint markings and thermoplastic marking strips to determine if these marking materials perform differently …
