Abstract:
This study focuses on improving the index-volumetrics relationship (IVR) for asphalt mixture performance prediction by replacing the original parameters, in-place voids in mineral aggregate (VMAIP) and in-place voids filled with asphalt (VFAIP), with more intuitive ones, in-place air voids (Va,IP) and effective binder content (ACEff). Using these new parameters, the IVR equation was redeveloped, resolving issues with Sapp trends as a function of air void content and enhancing the prediction accuracy for plant-mixed lab-compacted samples. The proposed method provides a practical approach for predicting field construction performance using the ‘four corners’ method.
