摘要
以高含蜡减渣为原料 ,在原有调合法生产道路沥青的基础上 ,通过催化—丙脱—沥青调合组合工艺研制出满足重交通道路沥青标准 GB/T1 5 1 80— 2 0 0 0中 AH-5 0至 AH-1 1 0各牌号要求的重交道路沥青。该工艺不仅能提高脱沥青油 (DAO)的收率 ,而且脱沥青油(DAO)延度提高 ,大大改善了丙脱沥青的性质 。
Heavy-traffic asphalt AH-50 to AH-110, which are up to Standard GB/T15180-2000,have been prepared successfully from high-wax vacuum residuum with a blending process,which may increase the yield and ductility of DAO, and hence improve the flexibility of asphalt production.
