简介
Warm Mix Asphalt (WMA) is a sustainable technology that allows asphalt mixtures to be produced and compacted at lower temperatures in comparison to hot mix asphalt (HMA). Several concerns have been raised regarding the determination of mixing and compaction temperatures (also termed as production temperatures) for WMA mixtures. An attempt has been made through this study to comprehensively understand and explore the procedures for appropriate measurement of production temperatures of WMA mixtures. One base asphalt binder and five different warm mix additives (with varying dosages) were used in this direction. Rotational Viscometer (RV) and Dynamic Shear Rheometer (DSR) were employed to analyse the unmodified and warm mix modified asphalt binders. A workability prototype was fabricated, and a workability-based approach was proposed to systematically assess the production …
