Evaluation of Selected Performance Properties of Nanoclay-Modified Asphalt Binders
Asphalt binders are often modified with additives such as acid, polymer, or a combination of multiple additives to achieve improved performance to sustain heavy loads and adverse weather conditions. According to some previous researches, nanoclay can be a good alternative of currently practiced Styr...
