以辽河AH-90沥青为基质沥青,以自制的Gemini季铵盐阳离子表面活性剂为乳化剂,以橡胶粉为改性剂,制备改性乳化沥青。本文采用二种方法考察了改性乳化沥青的感温性能,实践证明用针入度指数法来考察沥青的温度敏感性最佳。
Taking Liaohe AH-90 asphalt as matrix pitch, homemade Gemini quaternary ammonium salt cationic surfactant as emulsifier and rubber powder as modifier to prepare modified emulsified asphalt. In this paper, two methods were used to investigate the temperature-sensitive properties of the modified emulsified asphalt. Practice has proved that the temperature sensitivity of the asphalt is the best measured by the penetration index method.
