| Abstract | ||
| In the recent years an important trend has been established towards the use of heavier highway md aircraft wheel loading. The high axle loads lead to excessive permanent deformation in asphalt pavements, especially at high temeratures in hot regions. The main objective of this research is to study the effect of test temperatures on the creep behavior of asphalt concrete mixtures. Dynamic creep test was used for this purpose. Creep strain, mix stiflkess modules and rate of deformation were obtained as a function of axial applied stress and/or test temperature. It is concluded that the creep strain, rate of deformation 'and mix stiffness modules depends upon the bitumen stifhess, and influenced proportionally by variation of test temperature. | ||
