عنوان مقاله [English]
Recycling waste materials into the roller compacted concrete mixes improves their performance and has been attracted grate attentions recently; in this regard using RAP has been increasingly developed. Since it contains 3 to 4 percent asphalt binder which is valuable as waste material; gained grate demands in road construction as partial replacement of aggregate. The previous researches on manipulating RAP in concrete pavements revealed noticeable decrease in compressive and flexural strength of concrete. However there are not enough investigation in this part and it seems that there is an urgent need for extended research in this area. In this study the influence of utilizing RAP in concrete mixtures on toughness behavior of mixtures has been elaborated. Ignoring the type of waste materials which could be influential itself, the effect of gradation and RAP content (0, 25, 50, 100%) in RCC mix design is considered. Finally 32 different RCC mix design with different RAP and cement (250,300,350,400 kg/m3) content with 2 different gradations were developed. The effect of various parameters on mechanical properties of RCC such as flexural and compressive strength and toughness index of mixes were noticed.
