Abstract:FHWA is proposing regulations to guide minimum pavement marking retroreflectivity levels, which poses a potential challenge to MassDOT, as the current practice of visual inspection is labor intensive, and the results can be subjective. To address the identified challenges and needs from MassDOT, the objective of this research is twofold: (1) to serve as a proof of concept for the use of mobile LiDAR to locate and assess the pavement markings for selected testing sections by developing and evaluating new automated LiDAR processing algorithms, and (2) to investigate the feasibility of identifying deterioration trend of retroreflectivity condition. This study has developed a complete pavement marking inventory with retroreflectivity conditions for the 14 selected testing sections and also compared historical and current data to inform the deterioration trends of three types of marking materials, including polyurea, epoxy, and thermoplastic. The findings of this study will guide the future phases of the study with a larger selection of testing sections, material types, and roadway characteristics. The outcomes of the series of studies will help better define the benefit-to-cost ratio for different marking materials and eventually lead to the development of MassDOT’s pavement marking standard.
