Bitumen Number 40 Description
Bitumen 40 is a type of hard grade building asphalt with penetration starting from #40 that is why it is famous asphalt number 40. Bitumen Number 40 is available in bag and drum also the bulk tanker. This grade of asphalt building material is mostly using in the eastern Asia market especially Taiwan and China also the Philippine and Indonesia. Bitumen grade 40 is the most consumable hard asphalt which is a semi-solid grade of pure petroleum bitumen categorized in polycyclic aromatic hydrocarbons is normally used for different purposes in the construction business.
