This study investigates the correlation between asphalt mixture elastic modulus and surface temperature, using fundamental experiments with local vibration tests as control indicators. To improve accuracy in assessing structural condition, Falling Weight Deflectometer (FWD) tests were performed on newly constructed asphalt pavements in Cambodia. The results revealed that the temperature-elastic modulus relationship derived from the experiments closely matches the modulus values obtained from field measurements in healthy condition. This alignment confirms that the study’s back-calculation method enhances analysis accuracy, enabling the use of the experimentally derived equation to determine asphalt layer elastic modulus. This approach provides a refined method for evaluating asphalt pavement structural integrity under varying temperature conditions.
