However, the innovative use of geopolymer in warm mix asphalt (WMA) additives is expected to pave the way for using industrial wastes and reduce the asphalt-mixing temperature. Both materials are important in utilising substantial waste resources and enhancing environmental protection [ 6, 7, 8, 9 ].
The results showed that increasing the geopolymer additives increased the rutting factor, indicating that the asphalt binder becomes stiffer and more elastic, and hence more resistant to...
The geopolymers from these materials influence the rheological and physical properties of Geopolymer in Asphalt Pavement asphalt binders. Geopolymers can enhance asphalt mixture performance, such as stability, fatigue, Modification and Construction—A rutting, and low-temperature cracking.
Using geopolymer as a modifier for asphalt binders and mixtures gained momentum for investigation in recent decades. Limited research investigations attempted to link the effect of temperature and traffic loading on the rheological properties and performance of geopolymer-modified asphalt binders.
The source, composition, and properties of the base binder along with the type and amount of warm-mix additive play a major role in the performance of warm mix binders [155, 156]. Chemical additives have little effect on high, intermediate, or low-temperature characteristics, while technologies in reference to binder foaming may have …
This study mainly emphasizes to compare the behavior of bituminous concrete mix and Warm Mix Asphalt (WMA). Bituminous concrete mix and WMA is prepared using lime (1% & 2%) as filler material. Zycotherm (0.1% by weight of binder) is adopted as chemical additive for the preparation of WMA.
