Description
Abstract. This study conducted in Kitchener, Ontario, presents a comprehensive analysis of monitoring the environmental and structural behaviour for two years in an instrumented pavement test section. Focusing on pressure, strain, moisture, and temperature measurements throughout the pavement structural layers, the re-search uncovers nuanced patterns. Temperature fluctuations exhibit distinct daily and seasonal variations, with depth-related temperature and moisture changes within the pavement structure. Moisture measurements reveal varia-tions across layers, aligning with precipitation patterns. Load assessments indi-cate consistent pressure variations, with some unexpected deviations between right and left sensor arrays. Strain analysis validates the impact of asphalt mat temperature and strain magnitudes (Granular materials and Hot Mix Asphalt), emphasizing temperature's influence on pavement behavior. Overall, this study provides valuable insights into the reliability of instrumentation data, dai-ly/seasonal variations, and the complex interplay of environmental factors in pavement performance.
