本刊讯:北京市政工程管理处利用乳化沥青制成袋装冷拌沥青混凝土。对沥青路面进行养护收到了可喜的成绩。北京市政处的科研人员是从去年开始研制这种袋装沥青混凝土的,当时他们只是看到日本专家来华座谈时带的一袋样品,经过反复试验终于制出国内第一袋袋装沥青混凝土,现在他们制成的袋装冷拌沥青混凝土可以存放两个半月而不破乳,使用仍和新制的一样。他们用此项成果修复的路面已达近千平方米,路面至今仍完好无损。
The newsletter: Beijing Municipal Engineering Management Department made of emulsified asphalt bags of cold mix asphalt concrete. The maintenance of asphalt pavement received gratifying results. Beijing Municipal Office of the researchers from last year to develop such bags of asphalt concrete, when they just saw the Japanese experts to visit a discussion with a bag of samples, after repeated tests finally made the first bags of domestic asphalt concrete , Now they are made of bagged cold mix asphalt concrete can be stored for two and a half months without demulsification, the use is still the same as the new system. The roads they repaired with this result have reached nearly a thousand square meters, and the pavement is still intact.
