Abstract
In Libya, many steps have been taken to extend the life of the pavement and improve the design of asphalt mixture to have a better connection to Libyan climate. This study is to evaluate the effect of some parameters on the performance of the asphalt mixture in hot arid weather as Libya. Two asphalt concrete mixtures were designed using two different binders, Performance Grade binder (PG70-10) and Pen Grade System (B60/70). These mixtures were formulated in accordance with the Marshall mix design method and the Superpave mix design method. Rutting test also tested these mixtures to evaluate the performance of the bituminous mixtures under certain conditional parameters. The study clearly showed that the asphalt mixtures with binder PG70-10 are slightly performed better than the mixtures with binder (B60/70) In addition, the results obtained from Superpave mix design test have shown a better performance indicator than those obtained with the Marshall Stability tests and they were superior at all stages of tests. These results provide a guide line to improving the production of the hot mix asphalt (HMA) and a foundation for different paving mixes, by adopting PG binder and Superpave Gyratory compactor (SGC) instead of Marshall hammer and binder B60/70.
