Abstract:
     An asphalt impregnant is prepared from coal tar asphalt or petroleum asphalt through pressurizing and heat treatment. Its final performance can be controlled by reaction time, reaction temp and reaction pressure. Its advantages are high flowability and carbon output rate, simple process, low energy consumption, stable performance and high quality.
