What is modified asphalt? What are its classifications?
Feb 24,2026
Modified asphalt is an asphalt binder produced by adding external additives (modifiers) such as rubber, resins, high-molecular polymers, finely ground rubber powder, or other fillers to enhance the properties of asphalt.
There are two mechanisms for modifying asphalt: altering its chemical composition and uniformly distributing the modifier throughout the asphalt to form a specific spatial network structure.
Materials selected for modified asphalt: SBS, SBR, rubber powder, specialized aromatic oil, accelerators, stabilizers, etc.
Regional structure of SBS-modified asphalt: SBS phase, asphalt phase, and the interfacial layer between SBS and asphalt.
