Assessment of the effectiveness of various temperature correction factors in the retrocalculation of stiffness moduli of pavement materials

This project focuses on improving how we evaluate the condition of asphalt roads by studying how temperature affects the results of deflection tests, a common method for checking pavement strength. Since asphalt reacts differently depending on the temperature, ignoring this factor can lead to incorrect conclusions about road quality. The research will compare current methods with improved ones that take temperature into account, using real field data and simulations. The collaboration between ÉTS in Canada and UFPE in Brazil will benefit both institutions by combining their strengths—ÉTS’s experience with cold-climate pavements and UFPE’s expertise in modeling and analysis. The project will also help train a graduate student, promote international knowledge sharing, and support better, more cost-effective road maintenance strategies.
