Application of large deformation circular cylinder torsion test for identification of material model and parameters in case of modified binders
Abstract
Constitutive relationships for asphalt binders are usually formulated in the frame of small deformation theory, cf. [1]. However, in many of technological and operational processes during production and laying of asphalt mixes, the binders are subjected to large deformations. Polymer modified binders (eg SBS) in the range of operating temperatures exhibit elastic, viscous and plastic mechanical behaviour. Aim of this study is to describe the elastic properties of modified binders. Due to the large range of deformation the hyperelasticity theory is applied [2-5]. As a result, only processes with monotonic active load are described, at constant temperature and fixed deformation rate. To determine the material functions and parameters for hyperelasticity the results of torsion test (torque and compressive force) carried out in DSR are used, [6,7]. In order to interpret the results of the tests the theoretical solution of torsion boundary problem is applied [4,8].
