Abstract

Asphalt modification/reinforcement has received considerable attention as viable solutions to enhance flexible pavement performance. This is mainly prompted by the unsatisfactory performance of traditional road materials exposed to dramatic increases and changes in traffic patterns. This paper presents the evaluation of fatigue behaviour of nano reinforced Stone Mastic Asphalt mixtures. Fatigue is one of the most important distresses in asphalt pavement structure due to repeated load of heavy traffic services which occur at intermediate temperatures. There are different test methods used throughout the world to measure fatigue resistance for asphalt concrete mixtures. In this study, indirect tensile fatigue test was conducted to estimate fatigue number of asphalt mixture with different contents of nano SiO2 and Nano TiO2. The results indicated that the addition of different percentages of nano particles is capable to improve the shear modulus of modified bitumen. Also, modified SMA mixtures had more resistance against fatigue cracking phenomena.
