Penetration Bitumen

 

Bitumen, which are directly obtained from distillation tower in vacuum

Condition of refinery or are briefly processed under blowing operation, are referred penetration Bitumen of Grade pen and their naming process are based on the interval which their penetration grade (pen) is placed within them.

Blown Asphalt or Rubbery Grader

 

The produced bitumen of refineries which are in liquid or semi-solid state at environmental temperature, under blowing process, are converted to the bitumen of grade pen for application in road construction or solid bitumen of grade R for industrial application. For naming of bitumen of grade R, first starting from left, softening point (SR) and then penetration grade (PEN) are written: R (SP)/ (PEN). For example, bitumen R 85/25 is bitumen with softening point of 850and and penetration grade of 25 (0.1mm).
