Abstract

The invention provides an asphalt rapid heating system and process and a modified asphalt production method, and belongs to the field of petrochemical product processing. The asphalt rapid heating system provided by the invention comprises a matrix asphalt storage tank, a heat exchanger group and modified asphalt production equipment, which are connected successively in an asphalt flowing direction through pipelines, wherein the heat exchanger group communicates with the matrix asphalt storage tank through a circulating pump. Through the adoption of the asphalt rapid heating system provided by the invention, the temperature of matrix asphalt can be rapidly increased in the production process of SBS modified asphalt, and a technique meets requirements for the efficient and continuous production of the SBS modified asphalt.

Description

technical field [0001] The invention belongs to the field of petrochemical product processing, and in particular relates to a production process of SBS modified asphalt. Background technique [0002] With the rapid development of China's economy, China's highway construction also maintains a trend of continuous growth every year. One of the most important materials for highway construction is asphalt. Under the high-speed and heavy-duty transportation mode, the traditional heavy-duty asphalt pavement can no longer meet the needs of China's expressway development, and modified asphalt must be used. At present, the construction of China's expressways requires that the middle and upper layers must be mixed with SBS modified asphalt. Therefore, the demand for modified asphalt in China's highway construction is increasing every year. [0003] Since modified asphalt needs to be added with SBS, and the optimum temperature for the fusion of SBS and base asphalt is 175-185 degrees C...
