Abstract

ABSTRACT
In this study the use of marble dust, marble limestone and crushed marble collected during the shaping process of marble blocks has been investigated in the asphalt mixtures as filler material, limestone and sand. Six different asphalt mixes having marble dust, limestone dust filler, crushed marble, sand, limestone aggregate and marble aggregate were prepared. The optimum binder content was then determined by Marshall test procedures. The study showed that marble's wastes, which are in the dust form and crushed form could be used as filler material and sand in asphalt mixtures where they are available. This may reduce the cost of transportation compared to that when using ordinary paving materials.
