Bitumen Penetration Grade 20/30

Bitumen 20/30

General description of Bitumen Penetration Grade 20/30

GLB – bitumen penetration grade 20/30 is hard penetration grade bitumen using as paving grade bitumen suitable for road construction and repair also for the production of asphalt pavements with below technical specification. This grade of bitumen is mainly used in the manufacture of hot mix asphalt for bases and wearing courses.

Softening point and penetration of bitumen 20/30

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 20/30 has penetration between 20~30 desi-millimeter and softening point between 55 ~ 63C. The penetration grade bitumen 20/30 has a thermoplastic property which is like as synthetic resin material which gets softer with heating and hardens when cooled. This grade of bitumen 20/30 has very strong viscosity compare to other grades.

Guaranty/warranty of bitumen 20/30

GLB guaranty the quality of bitumen 20/30 with arrangement of international inspector to check quality and quantity of the bitumen during the loading to vessel and controlling the production by QC by batch test report before shipping. GLB guaranty the quality to meet with ASTM/EN 12591.
