 This synthesis provides an overview of the latest updates on polymer-modified bitamins, PMBS. The study reviews recent papers related to modified bituminous materials, technologies, and advances. It is divided into two sections. The first investigates the chemical structure and microstructural systems of bitamin, while the second focuses on bitamin modification for enhancing its engineering properties in paving and industrial applications. The research highlights the importance of the chemical composition of base bitamin for modification and shows that some polymers slash additives can improve certain aspects of neat bitamin properties but may cause compatibility problems in storage and production. Waxes are found to be effective in improving the compatibility of polymers with bitamin and have benefits for warm mix asphalt, WMA, production.
