Abstract：On account of the early damage of semi-rigid base asphalt pavement and current heavy maintenance and repair tasks，the technical characteristics of grouting materials for asphalt pavement base were proposed through a comparative analysis of application characteristics between geopolymer grouting materials and high polymer grouting materials. Based on the statistic analysis of structure design data for typical semi-rigid base asphalt pavement，the amount of emulsified asphalt and latex powder were determined by means of studying the influence of their amount on the hydration process and stiffness of cement. According to the technical performance and construction characteristics of the prepared materials，we analyzed application prospects and proposed corresponding engineering application fields.
