摘要
Abstract
In order to study the influence of warm mix agent EC-120 on the rheological properties of SBS modified asphalt,the effects of warm mix agent EC-120 on the high-temperature viscosity,high-temperature resistance to rutting,and low-temperature resistance to cracking of SBS modified asphalt at different dosages(2%,4%,6%)were studied using the Blockfield viscometer method,DSR and BBR tests.The effects of 4%EC-120 on the aging performance of SBS modified asphalt were analyzed using the rutting factor and creep stiffness aging index as indicators.The results show that warm mix agent EC-120 can significantly reduce the high-temperature viscosity of SBS modified asphalt and improve its high-temperature resistance to rutting,but it will have a negative impact on the low-temperature crack resistance of SBS modified asphalt.EC-120 can improve the aging performance of SBS modified asphalt and slow down the aging rate.It is recommended that the EC-120 warm mix agent dosage be 4%.关键词
