The effectiveness and efficiency of pavement maintenance processes can be significantly improved by adopting a continuous monitoring approach. Therefore, since June 2023, pavement data has been collected and analyzed from a new instrumented section built in the access road to the Edmonton Waste Management Center (EWMC), located in the Northeast of the city of Edmonton, Alberta, Canada. The data has been continuously recorded and stored locally, and afterwards processed. This research provides meaningful information regarding both structural and environmental parameters, such as induced strains and stresses, soil temperature and soil moisture content, which are directly related to the pavement performance. In addition, a Weigh in Motion (WIM) system was used to provide detailed information about the traffic conditions. Furthermore, a Dynamic Modulus (DM) test was conducted on asphalt samples, in addition to other tests on soil samples, including grain size distribution and optimum moisture content. Both asphalt and soil samples were collected during the construction of the new instrumented section. Based on the characteristics of the asphalt and the soil determined by the performed tests as well as the axle load information from the WIM system, it was possible to calculate strain values by finite elements pavement analysis and design software. The calculated values were then compared with the measured strain values from the sensors. Through this comparison, the ultimate goal of the study was achieved by identifying areas of convergence and divergence, providing a comprehensive understanding of pavement behavior as well as a foundation for refining data collection and analysis.
