In addition, asphalt mixtures with RCA, whose binder contents were determined from the Superpave mix design method, were utilized and evaluated against Marshall design criteria in order to effectively reflect both field specifications and field compaction conditions in South Korea. For this verification, the Indirect Tensile (IDT) strength test, Kim test, wheel tracking test, and tensile strength ratio test accompanied by fundamental material property tests were performed on asphalt mixtures with four types of aggregate blends. In this research, the performance of HMA mixtures with RCA is quantitatively evaluated using various tests to verify the applicability of RCA as aggregate for HMA material. In many cases, these properties of RCA that lead to poor engineering qualities are the major reasons that RCA is not recommended as aggregate for Hot Mix Asphalt (HMA). (3) Length change rate in drying contraction of the recycled aggregate concrete made of the recycled aggregate was lower than the ordinary concrete made of the broken stone by in all blending.Recycled Concrete Aggregate (RCA) is different from natural aggregate because of RCA’s cement paste and contaminants that cause low density and high porosity. (2) Carbonated thickness of the recycled aggregate concrete and the normal concrete was similar or it appeared with the tendency which it diminishes more or less. (1) Resistibility to the freeze and thaw of the recycled aggregate concrete showed relative dynamic modulus of elasticity over which is very good, and all cycles show dynamic modulus of elasticity which is improved compared with the relative dynamic modulus of elasticity of ordinary concrete made of broken stone. The object of this study is to prove the quality and reliability of recycled aggregate concrete by finding a way to improve the durability of the material through the experiment on the accelerated carbonation, freezing and thaw, and drying shrinkage, analysing the influence on the durability to Promote more active use of recycled aggregate concrete. © 2016, Editorial Office of Journal of Building Structures. Compared with the recycled concrete mixed without fly ash, the total specific creep of concrete specimens is the smallest and reduced by 14.6% when the fly ash proportion is 40% after loading 360 d. The creep of recycled aggregate concrete can be improved effectively by adding proper amount of fly ash. pre-wet, steep liquor wrapped stone craft and incorporation of silica fume steep liquor wrapped stone craft) have obvious effects on the decrease of the creep of RAC, which can reduce the creep deformation of RAC by 10%-25% after loading 150 d. The test results indicate that the total specific creep of RAC with 50%, 70% and 100% replacement rates of the RCA increase by 18.5%, 47.7% and 52.7% respectively after loading 150 d, compared to that of normal concrete (NC). The influences of different preparation methods, replacement rate of RCA and proportion of fly ash on creep performance of recycled aggregate concrete(RAC) were investigated. Recycled coarse aggregate(RCA) was produced by waste concrete, and then used to replace natural aggregate with different replacement rates.
