• Abstract:
  This research evaluated pavement marking performance and developed useful degradation models for thermoplastic ; and paint pavement markings which can help North Carolina meet the pending FHWA minimum retroreflectivity ; requirements. The impacts of several important factors (such as lateral location, directionality, region, and ; pavement roughness) on pavement marking retroreflectivity were evaluated. With two large datasets in hand, we ; determined whether these factors had significant impacts on marking retroreflectivity. Image processing techniques ; were used to analyze pavement marking surface glass bead density. We were able to explain why paint marking ; retroreflectivity values degraded over time by evaluating the impact of bead density on paint marking ; retroreflectivity. The research reviewed existing marking retroreflectivity degradation models and developed useful ; new models for both thermoplastic and paint pavement markings in NC. The research presented a transportation ; asset management system framework for estimating the current and future condition of pavement markings. The ; research outcomes enable the NCDOT have a better understanding of thermoplastic and paint pavement marking ; performance, which can lead to cost saving by maximizing pavement marking service lifecycles.
