Prediction of linear viscoelastic behaviour of asphalt mixes from binder properties and reversal
The linear viscoelastic (LVE) behaviour of bituminous materials (observed in the small strain domain) is considered for road design. The objective of this paper is to investigate the links between the LVE properties of binders and asphalts mixes. Complex modulus tests were carried out to determine the LVE behaviours of a bituminous binder and two mixes produced with this bitumen. Dynamic Shear Rheometer (DSR) tests and tension-compression tests (using a Métravib device) were performed on the bitumen. Complex modulus E* and complex Poisson's ratio v * of mixes which characterize the (LVE) properties in 3 Dimension (3Dim) were measured using tension-compression tests. The experimental results show the dependence between mixes and associated bitumen behaviours. The prediction of LVE behaviour of bituminous mixes from bitumen properties was carried out using the SHStS (Shift-Homothety-Shift and time-Shift) transformation developed at ENTPE.
