0引言随着沥青路面技术的不断发展与进步,路用沥青及改性沥青日新月异,品种越来越多,性能也日渐提升。改性沥青由最初的单纯增加基质沥青粘度、提高软化点、改善温度敏感性,向彻底改变沥青性能、全面提升沥青混合料路用性能转变。近年来,各种特殊改性沥青技术(如温拌改性沥青、橡胶粉改性沥青、常温沥青、高渗透型乳化
0 Introduction With the continuous development of asphalt pavement technology and progress, road asphalt and modified asphalt with each passing day, more and more varieties, performance is also increasing. Modified asphalt from the initial simply increase the viscosity of matrix asphalt to improve the softening point and improve the temperature sensitivity to completely change the asphalt performance and improve the comprehensive performance of asphalt road performance changes. In recent years, various special modified asphalt technology (such as warm mix modified asphalt, rubber powder modified asphalt, asphalt at room temperature, high permeability emulsification
