Prediction of the rutting potential of bituminous binders using a stochastic approach

This work deals with the experimental characterization of the mechanical behavior of bituminous binders used in road pavement. First, conventional tests are used to determine the grade of four bituminous products with a Polymer modified one. Then, rheological experiments were performed to compare the viscoelastic properties of the different binders. Tests were carried out at least three times so that one can take advantage of the statistical collected data to define the available information used in the stochastic modeling. The parametric probabilistic model highlights the necessity to include experiments uncertainties into modeling for a safe and accurate prediction of bitumens ultimate properties.
