The asphalt pavement of a highway network degrades over time, with many factors influencing how well the pavement is able to resist this degradation and continue to meet service requirements. There are several different kinds and types of repair and rehabilitation treatments available for pavement upkeep, and choosing the most appropriate and cost-effective treatment for each specific case continues to be an ongoing and time-intensive process for many transportation agencies. A significant part of this process is the analysis of yearly survey data which captures various defects and imperfections in the highway network and ensuring that this data is both accurate and reliable. This paper uses data collected by an Automatic Road Analyzer (ARAN) vehicle during Nova Scotia’s 2014–2019 pavement condition surveys on highways which had had microsurfacing treatments performed during this period. The results show that rutting and roughness degradation curves can be used to estimate the relative efficiency and effectiveness of pavement rehabilitation treatments.
