Superpave规范对于改性沥青的有效性分析

Validation Analysis of Superpave Binder Specification for Polymer Modified Bitumen

分析Superpave结合料规范的特点 ,讨论规范指标用于评价改性沥青高温、低温、疲劳及老化等路用性能的有效性 ,并探讨其将来的发展方向。有关分析表明 ,现阶段的Superpave结合料规范是长期研究的中间成果 。

The advantage and limitation of SUPERPAVE binder specification for PMB are reviewed. The validation of SUPERPAVE evaluation methods on high temperatur e, low temperature, fatigue, and aging properties of modified binders, as well a s potential development of SUPERPAVE binder specification are investig ated. It is found that, SUPERPAVE binder specification is an intermediate produc t of the research program and needs further improvement.
