高软化点改质沥青的生产控制

Abstract

Abstract:

By increasing the temperature of the reactor，raising the vacuum level of the flash tank，and optimizing the process flow of the original modified asphalt plant，modified pitch with a high softening point of 118～130 ℃ and a coking value greater than 60% was produced.
