- Abstract
The raise in axle loads, heavy traffic, design and construction errors in the last two decade increase the failures such as rutting, fatigue and low temperature cracking. These deformations decrease the level of performance and service life of the roads. Aging phenomenon, which is defined as the hardening of asphalt binder due to loss of volatile components and oxidation, is the primary factor of the above-mentioned failures. This study aims to evaluate the current standard (AASHTO R30) regarding to the laboratory aging procedure with the new method proposed by National Cooperative Highway Research Program (NCHRP 09-54). In order to investigate the aging effects, the indirect tensile strength tests have been performed on unaged, short and long term laboratory aged asphalt concrete specimens. The aging level of the asphalt concrete specimens had been evaluated through aging indices.
