Carbon Reduction Effect of Crumb Rubber/SBS Composite Modified Asphalt
According to the rubber asphalt and crumb rubber/SBS composite modified asphalt applied in Enshi,the carbon reduction effect of crumb rubber/SBS composite modified asphalt was analyzed.Firstly,the life cycle assessment(LC A)of composite modified asphalt was established.Based on this method,the energy consumption and carbon emission were analyzed in each stage of raw material production,mixture mixing,ma-terial transportation,construction and maintenance,and the differences between crumb rubber/SBS composite modified asphalt and rubber asphalt were compared.Finally,the performance and carbon reduction effect of crumb rubber/SBS composite modified asphalt pavement was evaluated from the perspectives of replacing as-phalt with rubber,reducing the asphalt content in mixtures and prolonging the life of the pavement.
