BITUMEN 80/100 PENETRATION PAVING BITUMEN GRADE GENERAL DESCRIPTION
Bitumen Penetration Grade 80/100 is a standard penetration grade Bitumen usually used as a Paving Grade Bitumen suitable for road construction and for the production of asphalt pavements with superior properties. This grade of Bitumen is mainly used in the manufacture of hot mix asphalt for bases and wearing courses. Penetration Grade Bitumen supplied by DAYAco GROUP is petroleum grade bitumen, manufactured from fractional / vacuum distillation of crude oil. The Bitumen supplied by DAYAco GROUP is produced from vacuum residue (short residue) feedstock. Penetration Grade bitumens are specified by the penetration and softening point test. Designation is by penetration range only. The penetration grade bitumens have a thermoplastic property which causes the material to soften at high temperatures and to harden at lower temperatures. This unique temperature/ viscosity relationship is important when determining the performance parameters such as the adhesion, rheology, durability and application temperatures of bitumen.
DAYAco GROUP guarantees that the Bitumen Grade 80/100 it supplies under its offers is produced in compliance to and is in conformity to Standard AASTHO M20-70 and ASTM D946/D946M and meets the following specification requirements.
