With the rapid development of highway construction, the asphalt industry absorbs foreign advanced technology and experience. PetroChina, CNOOC and Sinopec have studied the formulation and indicators of SBS modified asphalt and rubber powder modified asphalt. At the same time, there are normative standards for modified asphalt equipment, such as colloid mill technology, shearing machine technology, mixing technology, dispersion technology, dissolution technology, and road maintenance technology. At the same time, international and domestic academic exchange meetings are held frequently for information transmission and sharing. This puts higher demands on equipment manufacturers. In 2003, Xinruidu Company began to use the colloid mill and shear technology to manufacture high-shear emulsifier equipment for Zhenhai refinery, road asphalt supplier and construction unit in Tangxia Town, Guangdong Province.
