ABSTRACT
Abstract This report describes a development of new asphalt mix design procedure which i s better i n d i c a t o r of road performance i n Dubai. The Marshall method has served us well over the years but as wheel loads and t i r e pressures increase, and as temperature i s high, there was a need for an update of mix design procedures. This new method allowed the incorporation of aggregate s i z e larger than 25mm, and the use of v i b r a t o r y compaction apparatus with 6" mold s i z e diameter. Results from the mix design study i n d i c a t e d that when compared to the conventional mix c h a r a c t e r i s t i c s , the intr o d u c t i o n of larger stone to the asphalt mixture improves i t s p r o p e r t i e s considerably.
