摘要
在实验室对伊索70号沥青进行热储存试验,同时与生产装置的热储存进行性能比较。结果表明,沥青热储存的稳定性与调合组份、储存温度、储存时间、储存容器、储存容量密切相关。温度越高性能变化越大。储存容器越大越满,热老化性能越稳定。140℃下储存,实验室热储存1 d的沥青性能与工业装置热储存15 d的性能相当。
The hot storage stability of Yishuo No. 70 asphalt was examined in the laboratory and was compared the performances with those stored in the normal production device. The results showed that the hot storage stability depended on asphalt compositions, storage temperature, storage time, storage vessel and storage capacity. The higher storage temperature, the more the properties changed. The larger the container size and the fuller the container filled, the hot aging property was more stable. The hot storage property of asphalt storaged one day at 140℃ in the lab equaled to storage 15 days in the production device.
