Softening point and penetration of bitumen 40/60

Penetration grade bitumen supplied by GLB is pure petroleum grade bitumen, manufactured from vacuum bottom by passing hot air. The bitumen supplied by GLB is produced from remain of crude oil after cracking and removing hydrocarbon. Penetration grade bitumen 40/60 has penetration between 40~60 desi-millimeter and softening point between 48 ~ 56C. The penetration grade bitumen 40/60 has a thermoplastic property which is like as synthetic resin material which gets softer with heating and hardens when cooled. This grade of bitumen 40/60 has very strong viscosity compare to other grades.
