dc.description.abstractRutting is recognized to be the major distress mechanism in flexible pavements. Rutting is caused by the accumulation of permanent deformation in all or some of the layers in the pavement structure. The accumulation of permanent deformation in the asphalt surfacing layer is now recognized to be the major component of rutting in flexible pavement. Rutting especially is a major problem for roads with a relatively steeper gradient and high pavement temperature like Goha Tsiyon – Dejen Road and Adama - Metehara Road of Ethiopia. The binder grade used was 60/70 according to ERA design manual and no modifier was used. This study, thus, attempts to evaluate the rutting potential of the asphalt concrete mixes prepared with different binder grades and modifiers. The different binders were compared by making specimens of the mix design. A wheel Tracker called Quan Zi Dong Che Zhe Shi Yan Yi, a Chinese device, was used to evaluate rutting performance of the compacted samples. The testing and statistical analysis of the rut depths provides evidence that the mix with 40/50 binder grade performs better than 60/70 and the use of modifier (NES) in the asphalt concrete mix provide mixes with superior performance.
