| 요약 | Mixture design is the starting point of the asphalt production line. A low-quality mix design will directly result in pavements with poor performance. The goal of the mixture design has always been finding the optimum combination of the given components to yield asphalt pavements with good performance and long duration. However, due to the limitations in mechanical modeling and technologies in the past, the state-of-the-practice mix design is still an empirical method based on the control of volumetric properties. Since the late 1990s, researchers and pavement engineers have been seeking for design methods that can explicitly relate the candidate designs to pavement performance. In order to develop the design method that can find the "true" performance-optimum design, this research starts with developing mechanistic models for fatigue performance prediction. The Simplified ViscoElastic Continuum Damage (S-VECD) model is a mechanical model describing the change in material constitutive relationship as fatigue damage evolves. It can predict the material behavior with damage at different modes of loading and loading conditions. However, a failure criterion is needed to indicate the occurrence of macro-cracking. This research developed a failure criterion called the "DR" failure criterion based on the pseudo strain energy theory. It has been found that the average loss of material integrity up to failure is a constant for an asphalt mixture. It is a material property that can be used to predict the macro failure with given pseudo strain loading history. Compared with the old failure criterion, using the DR failure criterion, pavement engineers can reach the same or higher accuracy in prediction with few test replicates |
