Paving Grade Bitumen 20/30
1.Description of the product 
Paving grade bitumen 20/30 is the hardest paving grade bitumen offered by ORLEN Group. Its high softening point and high sensitivity to low-temperature cracks renders it recommendable solely for the binder and base courses of high-stiffness modulus asphalt concrete (AC EME) in regions with suitable climate. Courses with bitumen 20/30 should not be left over the winter period without being covered with the next course. Additionally, for main roads, in WT-2 part I of 2014 [6] are given special requirements and climate zones where specific types of binders (paving grade 20/30 or polymer modified) are used in AC EME,
