Abstract In this study, the thermomechanical behaviour of bituminous mixtures produced with CR by dry process was evaluated. Two bituminous mixtures were produced and tested: a reference one without CR and a second one with 3% of CR on the mixture weight. The used CR had a continuous 3/6 mm grain size distribution. Complex modulus was determined using tension/compression tests with sinusoidal loading, at nine temperatures from −25 °C to 50 °C and eight frequencies from 0.003 to 10 Hz with an imposed strain amplitude of 50 μm/m. For both mixtures, Time-Temperature Superposition Principle was validated. At high frequency/low temperatures, lower values of norm of complex modulus were found for the mixture containing CR. Tensile strength was determined using direct tensile tests on two samples at 10 °C and 3.125 × 10−2 %/min imposed strain rate.
