Performance Grades
This bitumen comes from blowing of hot air at the rate of two or three hundred degrees to the pure bitumen. The bitumen, as far as, is less powerful than pure, has greater gentleness and less sensitive to the change in temperature. The extraordinary classification of bitumen is invented by the SHRP.
In this classification based on knowledge of bitumen and character, with strong against the changes of from, resistance against the crack of the cold, resistance against the crack exhaustion, the foretelling of how hard the bitumen was to be found at the factory, and when affluence was developed, how hard the bitumen was defined by time, and how the temperature rate of the first rate of the first and second rate of the first.
