橡胶粉改性沥青技术可以大幅度提高路面的技术性能、使用性能和使用寿命,橡胶粉改性沥青技术在我国的应用和推广将带来巨大的经济和社会效益。文章将不同配比和掺配关系的橡胶粉改性沥青的针入度指标、延度指标、软化点指标等进行了对比试验,通过各项技术指标变化的规律,借鉴国家相关规范和其他省份相关标准,提出了橡胶粉改性沥青技术性能的控制标准,为实际应用提供方便。
Rubber powder modified asphalt technology can greatly improve the technical performance of pavement, performance and service life, rubber powder modified asphalt technology in China will bring great economic and social benefits and applications. In this paper, the comparisons of penetration index, ductility index and softening index of rubber powder modified asphalt with different proportioning and blending relationship were carried out. Through the rules of various technical indexes and the reference of relevant national norms and other provinces Relevant standards, proposed rubber powder modified asphalt technical performance control standards, to provide practical convenience.
