摘　　要：为了研究FCC废催化剂-沥青混合料的施工工艺,设计试验确定FCC废催化剂-沥青胶浆体系的离析情况,发现FCC废催化剂-沥青胶浆在160~170℃时会产生一定沉降;对5%掺量的FCC废催化剂-沥青混合体系频率扫描试验,发现温度>65℃时,FCC废催化剂与基质沥青间会产生离析,因此应采用干法施工;通过比较不同用量的FCC废催化剂对混合料基本性能的影响,确定FCC废催化剂的用量为替代20%的矿粉;通过铺筑试验段,验证了前期室内试验结论正确。In order to study the construction technology of FCC waste catalyst-asphalt mixture, the segregation of FCC waste catalyst-asphalt mortar system was determined by design experiment, it was found that FCC waste catalyst-asphalt mortar would settle at 160~170℃. The frequency scanning test of FCC waste catalyst-asphalt mixture system showed that when the temperature was higher than 65℃, segregation would occur between FCC waste catalyst and base asphalt, so dry construction should be adopted. By comparing the effects of different amounts of FCC waste catalyst on the basic properties of the mixture, the amount of FCC waste catalyst was determined to replace 20% of mineral powder. The conclusion of laboratory test was verified by paving test section.
