60-70 Bitumen

Bitumen Penetration Grade 60/70 or as per ASTM Bitumen Penetration Grade 60/70 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 spraying and chip applications. Penetration Grade Bitumen supplied is petroleum grade bitumen, manufactured from fractional / vacuum distillation of crude oil. The Bitumen supplied is produced from vacuum residue (short residue) feedstock. Penetration Grade bitumen is specified by the penetration and softening point test. Designation is by penetration range only. The penetration grade bitumen has 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. Characteristics and Specifications : The Bitumen Grade 60/70 supplied is produced in compliance to and is in conformity to AASHTO M20-70 and ASTM 0946/ D946M and is guaranteed to meets the following specification requirements.
