Researchers Develop Improved Pavement Management System

Posted: Dec 2, 2019

Researchers at the University of Wyoming have developed a pavement serviceability (PSI) model to provide a more realistic representation of county road conditions. They also tested smartphones (typically equipped with accelerometers, GPS receivers, and other sensors) as a cost-effective solution to minimize the costs of collecting pavement condition data. The researchers also developed an optimization methodology to identify the best mix of pavement preservation projects on county roads for maintaining pavement and improving safety. Maintenance planning takes budget limits, traffic volumes, weighted performance, and associated risk into account. The new methods were tested in Laramie County and the results indicate the improved pavement management system could be implemented statewide. The system will help local and state lawmakers make funding decisions to preserve local pavement networks.
