     nowadays, the re-use of recycled waste materials in asphalt concrete as modifier additives have large economic and environmental benefits. stone matrix asphalt (sma) is a conventional type of asphalt concrete and adding recycled tire rubber (rtr) can improve dynamic properties such as the stiffness modulus (sm). the objective of this study is to evaluate the effect of rtr on the stiffness modulus of sma. in addition, a model has been presented to describe the stiffness modulus of sma mixture containing rtr. the results of this research showed an improvement in the stiffness modulus of sma mixtures containing rtr in comparison with the conventional hot mixed asphalt (hma) concrete.
