A spatial asset management study through an analysis of pavement marking performance.

摘要

This research evaluates pavement marking performance characteristics of NC's highways and proposes asset management guidelines that will enable NC to effectively implement new Federal standards. Predictive models were developed and used to forecast the performance of pavement markings retroreflectivity over time. Consideration was given to the analysis of the relationships between pavement marking retroreflectivity values and variables such as marking color, marking age, pavement surface, and lateral location. Understanding retroreflectivity performance over time facilitated the development and implementation of guidelines and tools that will be used for holistic asset management. The guidelines and tools enable pavement-marking managers to focus limited resources where they are most needed and avoid replacing materials with effective life still remaining. Additionally, this research provides a means for NCDOT to establish the condition state of pavement markings throughout the State of North Carolina. This can be used to determined if they will be in compliance with pending minimum retroreflectivity standards that the Federal Highway Administration is proposing to publish.;The views expressed in this article are those of the author and do not reflect the official policy or position of the United States Air Force, Department of Defense, or the U.S. Government.
