Modern pavement condition assessment methods for periodic maintenance and rehabilitation planning on a network level: a United States approach with possible application opportunities in Southern Africa

Accurate condition assessment of an existing pavement forms an integral part of periodic maintenance and rehabilitation planning. Condition assessments of 415 miles of city road pavements were completed for a city in New Hampshire USA (city) using automated (video) data collection equipment. The quality of the process was controlled by verification / overlap field survey of digital analysis data by pavement experts at the beginning of the project to ensure that the process is in control, ongoing review of data images by independent assessors, identification of candidates for manual / field verification during daily review and manual verification throughout the project to include a minimum of 50 miles (approximately 10%) of roadway. The PCI rating for each pavement section was used with pavement deterioration models for the development of a multi-year pavement repair work plan. Alternative budget analysis scenarios based on alternative goals such as variations in budgets, and meeting pavement condition goals over 5-year and 20-year time periods were developed. Finally, the costs of manual and automated visual assessment methods are compared and discussed.
