Influence of Crumb Rubber Added by Dry Process on Linear Viscoelastic Properties and Tensile Strength of Bituminous Mixtures

Résumé

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.
