Abstract
In order to study the effect of graphene oxide dosage on the performance of SBS modified asphalt,three major indicators and storage stability tests were used to analyze the conventional performance of composite modified asphalt.Dynamic shear rheometer and low-temperature small beam bending rheometer were used to analyze the high-temperature and low-temperature rheological properties of composite modified asphalt.Finally,short-term and long-term aging were used to evaluate its aging resistance.The test results showed that:The addition of GO can improve the viscosity,temperature sensitivity and low-temperature ductility of SBS modified asphalt,and enhance its storage stability;At the same temperature,adding a certain amount of GO can significantly enhance its high-temperature deformation resistance and rutting resistance,but at the same time reduce its low-temperature stress relaxation ability and cracking resistance;Regardless of short-term or long-term aging,the addition of GO can reduce the aging degree of SBS modified asphalt and improve its aging resistance.Based on the comprehensive improvement effect and economy,it is recommended that the GO dosage should not exceed 0.5％.关键词
