Specific techniques and methods are described in this thesis in order to adapt Hot Mix Asphalt (HMA) so that desert sand can be used as a fine aggregate. In this way, the HMA can use a freely available local material. Such a locally available material is both accessible and low-cost but introduces the question of processing so that the final road construction is of comparable quality to thatget price
