Abstract

The motivation of this study is using plasma modification to significantly increase the performance of the hot mix asphalt. The surface of mineral filler was modified by using three different components: tungsten disulphide under peroxide (WS2-H2O2), tungsten disulphide under water (WS2-H2O) and silicon dioxide (SiO2) nano powders. Hot mix asphalts prepared with plasma modified mineral fillers were evaluated by Marshall Stability (MS) test. According to the results of modified SiO2 plasma samples were showed higher stabilities and better properties. Eco-friendly plasma modification technique provided homogenous, single step and fast processing for the modification of the asphalt materials.
