SBS/脱硫胶粉对复合改性沥青性能影响研究
Experimental Study on the Performance of SBS/Desulfurized Rubber Composite Modified Asphalt
摘要
Abstract
To compensate for the performance shortcomings caused by the large pore structure of fully permeable pavement,we prepared SBS/desulfurized rubber composite modified asphalt by mixing 10％,20％,30％(internally mixed)desulfurized rubber particles into SBS modified asphalt and conducted three basic indicators and anti-aging performance tests.Then,the microscopic properties and modification mechanism of SBS/desulfurized rubber composite modified asphalt were analyzed in depth using fluorescence microscopy and Fourier transform infrared spectroscopy.The results showed that the high temperature performance and adhesion to aggregates of the composite modified asphalt increased with the increase of desulfurized rubber particles.And the addition of desulfurized rubber particles improved the anti-ageing properties of SBS modified asphalt.In the modification process of SBS/desulfurized rubber composite asphalt,desulfurized rubber particles and SBS were evenly distributed in the asphalt phase.Shear homogeneous rubber particles were encapsulated by a continuous state structure formed by SBS to form a mesh system.The three were mainly physically blended,and some chemical reactions could also occur.关键词
