Relationship Between Ambient Conditions and Surface Pavement Temperature in Airport Asphalt Mixtures

Abstract: This study investigates the relationship between ambient conditions and surface pavement temperature in airfield asphalt mixtures. The aim of the study is to enhance the understanding of thermal behavior and performance in airfield asphalt mixtures. With the increasing demand for efficient airport operations, understanding how varying environmental factors, such as ambient temperature, windspeed and solar radiation influence the pavement temperature is critical for maintaining pavement integrity and safety. This presentation first discuss the installation of sensors on airport pavements under field environment. Field measurements were conducted to collect data on surface pavement temperatures in conjunction with real-time database of ambient condition factors at the trial pavement sections in the field. Statistical analyses were performed to identify correlations between the variables, and predictive models were developed to assess the impact of ambient conditions on pavement temperature. The findings reveal significant relationships between ambient temperature and surface temperature, emphasizing the importance of factoring in environmental conditions in the design and maintenance of airfield pavement systems. The results contribute to better material selection and could ultimately enhance the pavement durability and performance under diverse environmental conditions. This research underscores the necessity for ongoing monitoring and assessment to adapt to changing climate patterns and ensure the long-term functionality of airfield pavements.
