    Abstract

    Concrete mixes containing reclaimed asphalt pavement (RAP) were evaluated by the Superpave Indirect Tensile (IDT) strength test. The IDT strength and elastic modulus from Superpave IDT strength test correlated well with the splitting tensile strength and elastic modulus from the conventional concrete tests. Toughness determined by the area under the stress-strain plot up to the maximum stress was found to be capable of differentiating concretes containing different percentage of RAP. The IDT strengths of concrete were seen to decrease as the percentage of RAP and temperature increased. The addition of RAP in concrete noticeably reduced the elastic modulus but increased the toughness.
