Abstract
Cold recycling is a sustainable technology for the rehabilitation of bitumi-nous pavements. This study investigates the stiffness response of cement-bitumen treated materials (CBTM)manufactured with 80% reclaimed asphalt and treated with 2.0% Portland cement and 4.0% bitumen emulsion. Indirect tensile stiffness modulus tests were carried out to assess the strain dependence of stiffness at target horizontal deformation levels between 2 and 15 micrometers. Ultrasonic pulse velocity was also measured to evaluate stiffness at very low strain level. The tests were carried out at three temperatures (5, 20, 35C) on CBTMspecimens with 14 % of voids. The results showed that the CBTM stiffness decreased with increasing deformation level. Small-strain results can be used to estimate the linear viscoelastic response whereas damage can be observed when the deformation level is increased
