Abstract

The aim of this study is to investigate the effects of the production processes of nanoclay/polymer/bitumen nanocomposites on the performance of the asphalt mixture. In the study, styrene butadiene styrene (SBS) and ethylene vinyl acetate (EVA) with nanoclay (NC) were added to the bitumen by changing the priority of adding. Asphalt mixtures produced with polymer modified asphalt nanocomposites were evaluated by indirect tensile strength, modified Lottman method, repeated creep test and LCPC French rutting test. For EVA/nanoclay/bitumen nanocomposites, when EVA polymer was added to bitumen before nanoclay, higher water damage, cracking and deformation resistances were obtained. For SBS/nanoclay/bitumen nanocomposites, better results were revealed by adding NC before.
