选择胶粉改性沥青生产中涉及的搅拌方式、搅拌温度、搅拌时间以及胶粉掺量4个参数，控制3个参数不变，改变另一个参数，采用间接拉伸( IDT)试验研究生产工艺参数对胶粉改性沥青混合料强度的影响，并通过灰色关联方法分析各参数对混合料强度的影响程度。结果表明：高速搅拌方式生产的胶粉改性沥青混合料强度最大，简单搅拌最差；180~200℃生产温度能得到强度较好的混合料；搅拌时间并非越长越好，而是有一个合理的范围，建议选择1~1．5 h；从沥青的改性程度和施工和易性考虑，建议胶粉掺量为17．6%~22%；4个工艺参数中，胶粉掺量和搅拌时间是最关键的影响因素，搅拌温度次之，搅拌方式影响不大。

This paper selects 4 parameters, i. e. mixing mode, mixing temperature, mixing time and mixing amount rubber powder concerned in production of rubber powder modified asphalt, controls 3 parameters constant and changes the other parameter to research influences of production process parameters on strength of rubber powder modified asphalt mixture by means of indirect tension ( IDT) test, and analyzes degree of influences on strength of mixture through grey correlation method. The results show that the strength of rubber powder modified asphalt mixture produced in high-speed mixing mode is the best and high-speed shear is the worst; 180 ~200 ℃ production temperature can obtain mixture with better strength;mixing time is not good as long as possible but has a reasonable range, and 1~1. 5 h is recommended;in consideration of modified degree of asphalt and workability of construction, 17. 6% ~22% mixing amount of rubber power is recommended; in 4 process parameters, mixing amount of rubber powder and mixing time are most critical influence factors, mixing temperature is secondary, and mixing mode shows small influences.
