Exploring the Factors Influencing the Toughness and Tenacity Index of High Viscous Modified Asphalt
The effects of different types of base asphalt,modifier ratios,SBS modifier dosages,types of tackifying resins,additives,and preparation methods for toughness and tenacity of high viscous modified as-phalt were investigated.The results showed that using C based asphalt,with SBS addition of 8%,selecting phenolic resin or terpene resin as the resin type,without additives such as nano montmorillonite,and increas-ing the preheating temperature of the hemisphere head to 160℃,all were beneficial for the toughness and te-nacity indicators of high viscous modified asphalt.
