Evaluation of the Effect of Adding Bi Product Fillers on Hma Behaviour

Abstract

It is obvious that the type of fillers has a significant effect on the properties of hot-mix asphalt (HMA). It is very important to understand the effect of these types of fillers on the HMA and its performance. This paper represents laboratory research into the different effects of the bi-product fillers on the properties of HMA mixture. Four types of filler and three filler contents for each were used to obtain the characteristics of HMA and to characterize the effect of filler in HMA. The effects of filler on the of HMA mixture were also studied. The properties of HMA evaluated include Marshall Test and indirect tensile (ITS). The research results showed that fillers had a great influence on the properties of HMA. With the increase of filler content, some properties of HMA improved.
