Evaluation of rheological and microstructural behavior of modified asphalt binder with chitosan derived from shrimp shell powder

Results in Engineering
Chitosan derived from shrimp shells (SSPCH) was used for the first time as a biological biopolymer to modify the properties of bitumen across high, medium, and low-temperature ranges. Therefore, physical tests (penetration, softening point, and ductility)
