Conventional Bitumen

Bernet refinary is engineered to produce bitumen from vacuum bottom and addetives. We underestand valued customers not yet ready to enter the new era of economical and safer roads ; therefore, our facilitated production site can hold a competitive position and manufacture penetration grade bitumen that is not oxidized and is enhanced to best suit pavement construction projects.

Better technicality of penetration and viscosity graded bitumen and competitive pricing is our goal in this line of product.
