The importance of stone mastic asphalt in construction

Abstract

There are three major types of asphalt surfacings, characterized by a mixtureof bitumen and stone aggregate. These are: Dense Graded asphalt (DGA); Stone Mastic Asphalt (SMA) and Open Graded Asphalt (OGA). Asphalt surfacings differ by the proportion of different size aggregate, the amount of bitumen added and the presence of otheradditives and material. The first aim of this study is to provide an updated systematic review of the evaluation of stone mastic asphalt in construction. The second aim is to develop knowledge readers and researchers for advantages and disadvantages of stone mastic asphalt to help focus future research in this area.
