An effort was made to improve the separation issue of styrene-butadiene-styrene modifiers in styrene-butadiene-styrene-modified asphalt binders and further enhance their performance by adding nano-ZnO binder prepare compound modified binder. First, optimum dosage determined based on conventional tests, i.e., penetration, ring ball softening point, ductility at a fixed dosage; then, dynamic shea...

Dynamic mechanical properties including temperature effect, stress softening, and Payne effect are studied on the elastomer composites filled with soy protein or carbon black. The comparison of protein composite with well-known carbon black composites provides further insight into the protein composites. The elastomers filled with soy protein aggregates give substantial reinforcement effect whe...

Waste materials such as waste tire rubber (WTR), cooking oil (WCO), bio-oils, engine (WEO), and other oils have been the subject of various scientific studies in sustainable research field. The current environmental concerns identified to protect natural resources reuse materials. Accordingly, this work reviews use recycled mixed with (waste oil, oil) bio-oils that can be extracted from rejuven...
