Abstract

The Superpave Mix design method takes into consideration many factors that simulate the natural conditions besides the traffic loading which results in better rutting and fatigue resistances. Unfortunately, there are huge limitations to apply Superpave in Egypt because it is expensive, requires a lot of time in addition to the shortage of equipment. Therefore, the scope of this study is to find a relationship between Marshall and Superpave in order to improve the mixtures in terms of rutting and fatigue resistances. Two binders and two surface asphalt mixtures samples were designed by Marshall and compacted with the Gyratory Compactor. Dynamic Modulus and Flow Number tests were applied to the samples and finally analyzing the results of each test to determine the relationship between different performance tests. A directly proportional relationship was found between Marshall Stability results and Dynamic Modulus and Flow Number results which reflects on the rutting and fatigue resistances. Moreover, another sample was designed using Superpave then its properties were compared with the previous Marshall samples, it was found that the sample which was designed using Superpave has higher stability than the sample designed using Marshall although the same materials were used. Finally, Study the effect of applying Superpave aggregate gradation limits (control points and restricted zone) on the properties of a mixture designed using the Marshall, it was found that applying Superpave aggregate gradation limits on Marshall mix design method improve the mixture properties.
