Bitumen 60/70 is a type of penetrating bitumen. Infiltration bitumens or road grade, which are mostly used for asphalt production in the road construction industry, are obtained by performing an aeration process on the bottom of the distillation tower, known as vacuum baton, so that its permeability is between 60 and 70. Condition bitumen 60/70 depends on its temperature. The relationship between temperature and hardness of bitumen depends on the type of crude oil and its refining method, and the degree of permeability of this bitumen is between 6 to 7 mm, a degree of semi-hard permeability and as a heavy bitumen and suitable for road construction and repair.

Bitumen 80/100 is a standard bitumen of the type of penetrating bitumen, which is usually known as road grade bitumen and has excellent properties for road construction and construction of asphalt and road coating. Bitumen 80/100 is mainly used in making hot asphalt mixture. Penetration grade bitumen such as bitumen 80/100  are petroleum bitumen obtained from the distillation of crude oil. Basically, bitumen 80/100 is prepared from the remains of the distillation tower. Permeable bitumens are classified based on the amount of penetration and degree of softness, and the type of bitumen is expressed by the degree of penetration, so bitumen 80/100 has a penetration degree of 80 to 100

Gilsonite 5-10% is extracting from related mine which has the best quality natural bitumen and forwarding to the factory for crushing to finer Gilsonite lumps or Natural Bitumen powder.

Oxidized bitumen 115/15 is also known as oxidized asphalt 115/15, which is produced from petroleum bitumen during the heating and aeration process. Oxidized bitumen 115/15 is very important because it has a high flash point, high softening point and also high stability during melting.
