In the end of 1980s, China began to develop road on a large scale. At the same time, the drummed solid asphalt was vast
demanded. In the process of decanting and heating up the drummed solid asphalt, many serious problems occurred, such as high
cost, vast waste, high pollution, low efficiency, and so on.

During road development in China, vast bulk liquid asphalt needed to be transported. But in the process of transporting,
some problems occurred, such as poor heat-preserving capability and poor heating efficiency, high pollution, much
inconvenient filling and discharging of asphalt, and so on. These problems had badly affected the project progress.
In order to solve the problems, in 1993, we developed the first liquid asphalt tanker truck in the world, with the full
functions of automatic heating and heat-preserving system, and convenient pumping system for asphalt filling and
discharging.
