Long-term Pavement Marking Practices by James Migletz,Jerry L. Graham,National Cooperative Highway Research Program Pdf
TRB's National Cooperative Highway Research Program (NCHRP) Synthesis 306: Long-Term Pavement Marking Practices documents the current and best practices for managing pavement marking systems, identifies future needs, and addresses driver needs and methods of communicating information to drivers, selection criteria (e.g., reflectivity, pavement service life, wet weather performance), materials (e.g., color, durability, cost), specifications, construction practices, inventory management systems, and more.
Predicting the Initial Retroreflectivity of Pavement Markings from Glass Bead Quality by Omar Smadi Pdf
The report describes a laboratory test method to predict the initial retroreflectivity of pavement markings in the field based on the quality of the applied glass beads.
Traffic Control Device Analysis, Testing, and Evaluation Program by Melisa Dayle Finley,Adam Matthew Pike,Eun Sug Park,Lingtao Wu,LuAnn Theiss,Marcus Brewer,Kay Fitzpatrick,Raul Avelar,Timothy P. Barrett Pdf
This project provides the Texas Department of Transportation with a mechanism to conduct high-priority, limited-scope evaluations of traffic control devices. Work conducted during the 2018 fiscal year included: Evaluation of the safety of wet-weather pavement markings, Identification of effective work zone pavement marking removal techniques, review of raised retro reflective pavement marker practices in other states, identification of current uses and effectiveness of safety corridors, hosting of a wrong-way driving forum, assessment of pedestrian crashes on freeways and high-speed arterials, review of the design and application of lane control signs on frontage roads, review of the application of embedded light-emitting diodes in signs.
Durability and Retro-Reflectivity of Pavement Markings (Synthesis Study) by Yi Jiang Pdf
Waterborne paints are used to paint pavement markings (edgelines and centerlines) to provide guidance for motorists. The painted markings need to be repainted periodically as their retro-reflectivity deteriorates. The Indiana Department of Transportation (INDOT) repaints pavement markings at least annually. INDOT engineers would like to determine the feasibility of extending the time intervals of repainting pavement markings on at least some types of roadways. The purpose of this synthesis study is to accomplish the following: (1) to locate and assemble documented information on pavement marking durability; (2) to learn what criteria have been used in other states in measuring retro-reflectivity and scheduling pavement marking painting; (3) to determine the necessity of conducting full scale study on INDOT pavement markings; (4) to identify the type and cost of equipment required for retro-reflectivity measurements and conditions of operation of the equipment; (5) to organize, evaluate, and document the useful information that is acquired; and (6) to provide recommendations based on the evaluated information. This report presents the findings of the synthesis study on various pavement marking materials. It was found in this study that many state highway agencies have evaluated several types of pavement marking materials. The evaluation results include performance, cost, service life, and retro-reflectivity measuring equipment of marking materials. However, the results could vary from different sates. The information gathered through this study will provide INDOT engineers the state-of-practice of pavement marking materials in this country.

Effective Removal of Pavement Markings by Adam Matthew Pike,Jeffrey D. Miles Pdf
"TRB's National Cooperative Highway Research Program (NCHRP) Report 759: Effective Removal of Pavement Markings aids in the selection of safe, cost-effective, and environmentally acceptable practices for the removal of work zone and permanent pavement markings. The practices highlighted in this report emphasize minimal damage to the underlying pavement or visible character of the surface course." -- Publisher's description
Summary of Evaluation Findings for 30-meter Handheld and Mobile Pavement Marking Retroreflectometers by Highway Innovative Technology Evaluation Center (U.S.) Pdf
Prepared by the Highway Innovative Technology Evaluation Center (HITEC), a CERF Innovation Center. This report summarizes the results of detailed evaluations performed on four handheld and two mobile pavement marking retroreflectometers. The evaluations were designed to test the measurement bias, repeatability, and reproducibility of handheld and mobile retroreflectometers produced by several manufacturers.
