Predicting the Dynamic Modulus of Asphalt Concrete by Binder DSR Testing
This study proposes a completely new regression-based predictive model to estimate dynamic modulus (|E*|) of asphalt concrete (AC) from the dynamic shear modulus (|Gb*|) and phase angle (δb) of the asphalt binder used in the AC mix. Other parameters related to the aggregate gradation and volumetric are also incorporated in the model. In this study, a total of 10 AC mixes with 5 binders having different performance grades (PG) and sources were collected from the manufacturing plants. The AC mixes were compacted and cored to cylindrical specimens. After that, the samples were tested in the laboratory for |E*| at different temperatures and loading frequencies. The collected binders were tested for |Gb*| and δb using dynamic shear rheometer (DSR). The statistical comparison shows that a fairly accurate estimation of |E*| can be found by using this new |E*| predictive model.
