Abstract

Abstract:

Polymer modified asphalts were prepared with SBR, XSBR,SBS under oxidation or sulfurization conditions using a special mixing technique. The low temperature properties of the binders were greatly improved, the dynamic mechanical properties of SBR-modified asphalts before and after oxidation or sulfurization were characterized at -30~100 ℃ by using dynamic shear rheometry. The results show that the addition of SBR1500 increased the binder elasticity at low temperature. And sulfurization modification is improved the complex modolus G* and elasticity property at high temperature, when G*/sinδ=1 kPa, the temperature of PMA is 10 ℃ higher than the base asphalts after sulfurization, also the δ became smaller than the base asphalts, their temperature susceptibility is reduced to a great extent.It indicates that the viscoelasticity of the modified binder had been improved effectively at the high temperature. And the temperature susceptibility of the vulcanized-SBR asphalts were reduced to a great extent, their properties were improved apparently from low to high temperature, their application would be developed widely in the high

temperature environment conditions.

摘要： 在基质沥青中加入一定量的 SBR、XSBR、SBS,观察对沥青材料常规性能以及-30～100℃下动态力学流变性能的影响。结果表明,加入粉末 SBR1500后改性沥青材料薄膜前后的延度和流变性能都有明显的改进,而硫化共混改性可显著提高低温下改性沥青的粘弹性能,低温性能明显改善;同时高温性能得到提高,改性沥青的车辙温度(G*/sinδ= 1 kPa)比基质沥青提高约 10℃;粘度增大,复合模量提高,在高温区的相位角和损耗因子变小,从而改善了沥青高温粘弹性能。硫化共混改性沥青对使用环境的温度敏感性变小,使改性沥青的高低稳定性能均得到改善,可在高温环境下使用,拓宽了 SBR改性沥青的使用范围。
