【摘要】 采用配方均匀设计方法,制定试验方案,对FCC油浆与丙脱沥青调合生产重交通道路沥青进行试验研 究。建立了调合组分与调合沥青物性的数学模型,定量地反映了调合组分对沥青物性的影响。配方均匀设计方法 减少了试验次数,准确的预报了产品沥青的调合比例,可用于指导调合重交通道路沥青的工业生产。更多还原

【Abstract】 FCC slurry blending with the asphalt from propane deasphalting unit to produce heavy traffic paving asphalt has been tested by adopting uniform recipe design scheme. The mathematic models for blending components and blended asphalt properties have been established and the influence of blending components on asphalt properties has been quantitatively reflected. Test times have been reduced with the uniform recipe design and the blending ratio of product asphalt has been exactly predicted. So it can be used to direct commercial production of heavy traffic paving asphalt.更多还原
