文摘

A new technique is introduced to mix the modified-sulfur (Googas) with asphalt binder. Sulfur extended asphalt (SEA) mixture can significantly improve resistance against rutting phenomenon. Nano-antistripping agent (NZ), improved tensile strength of SEA mixture. NZ improves moisture sensitivity and mechanical properties of SEA mixture. Fatigue life of SEA slightly improved due to NZ-modification.
