Abstract

The temperature of the asphalt concrete AC is one of the most important environmental factors that influences flexible pavement performance. The possibility hazard of temperature change raises attention in how it may affect the deterioration rates (deflection, strain and stress distributions) in flexible pavement and how pavement service life would be changed as a result. A change in the AC temperature directly influences the stiffness of the asphalt-bound layers, which modifies the stress statues inside the pavement. This alteration in stress can influence the stiffness of the underlying unbound layers since they generally show stress reliance. Due to these relations are nonlinear, the additional pavement life lost at higher than average temperature is not replaced by savings at lower than average temperature. For that, the deterioration amount are overvalues when average pavement temperatures are used for determining the asphalt stiffness. The objective of this research was to study the pavement temperatures throughout the year in Egypt on performance and life of seven pavement sections with different stiffness or thickness using mechanistic-empirical method to investigate the most influential characteristic under temperature change for improving the design of pavement structures. The results revealed the significance of the impact that climate change may have on the performance service life of flexible pavements. These changes may impact the pavement life cycle cost and thus their impact on future maintenance requirement should be investigated.
