Bitumen Penetration Grade 35/50

General Description of Bitumen Penetration Grade 35/50

Therefore Bitumen Penetration Grade 35/50 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. Meanwhile 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 35/50

Therefore Penetration grade bitumen PUBLTD co supply is pure petroleum grade bitumen. Also manufacture from vacuum bottom by passing hot air. Also The bitumen PUBLTD co supply , produce from remain of crude oil after cracking and removing hydrocarbon. Therefore Penetration grade bitumen 30/40 has penetration between 35~50 desi-millimeter and softening point between 55 ~ 63C. Meanwhile The penetration grade bitumen 30/40 has a thermoplastic property which is like as synthetic resin material which gets softer with heating and hardens when we cool that. Also This grade of bitumen 30/40 has very strong viscosity compare to other grades.

Guaranty|warranty of Bitumen Penetration Grade 35/50

PUBLTD co guaranty the quality of Bitumen Penetration Grade 30/40 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. In addition PUBLTD co guaranty the quality and to meet with ASTM/EN 12591.


Difference between Bitumen and Asphalt

Certainly It`s actually liquid binder that holds asphalt together. Meanwhile the usage of bitumen is asphalt.

In conclusion, A bitumen-seal road has a layer of bitumen sprayed and then cover with an aggregate. Also This is then repeat to give a two-coat seal.

As a result, Most of manufacturer provide asphalt a plant that heats, dries and mixes aggregate, bitumen and sand into a composite mix. It is then applied through a paving machine on site as a solid material at a nominated or required thickness, relative to the end use. Asphalt results in a smoother and more durable surface than a bitumen-sealed road.
