ABP bitumen primer 80/100

Oxidized bitumens  such as our ABP PRIMER - produced by more vigorous air blowing; they are more 'rubber like' and less temperature susceptible than the paving grades.

Theabove are the typical Penetration or Paving Grades of bitumen.Additional processing provides other grades of bitumen products such as:

Thehigher boiling  point  fractions are then drawn - off via a heatexchanger and enter a vacuum distillation column. This process producesa "short residue" that is used to  manufacture  several  grades of bitumen.  The  pressure and temperature conditions  within  the vacuum process  will  determine the hardness of the short residue, and as such  the  grade  of  bitumen produced. The short residue may befurther modified by   'air blowing'  in which  air is  passed  throughthe residue at temperatures of 250 - 300 degrees Celsius.

Bitumenis produced from selected crude oils through a process of fractionaldistillation. The crude oil is heated to temperatures of between 300and 350 degrees Celsius and fed into a distillation column allowing thelightest fractions of the crude to separate, through vaporization, fromthe heavier fractions, which remain liquid.
