摘要
分析了机场专用改性沥青的质量特点,针对黏度和软化点等高温性能指标要求,研制了适宜的沥青及改性配方工艺,筛选研究沥青添加剂掺炼到改性沥青原料中按照配方工艺生产出了机场专用改性沥青,其沥青混合料AC-13和AC-20路用性能满足JTG F40—2004要求和工程要求,铺装机场路面满足设计要求。
This article analyzed the quality characteristics of special modified asphalt for airport.In view of the high temperature performance indexes such as viscosity and softening point,suitable asphalt and modified formula technology were developed.Asphalt additives were blended into the.modified asphalt materials to produce special modified asphalt for airport.The asphalt mixture AC- 13 and AC- 20 could meet JTG F40-2004 and engineering requirements,and pave the airport road as expected.
