Inexpensive quality bitumen 60/70

Bitumen penetration grades 60/70 are pointer penetration values ​​typically between 60 and 70 under standard test conditions
Used as a paving grade. Asphalt is suitable for the production of hot mix asphalt for foundations and pavements and asphalt for roads
put up. The permeation grade bitumen provided by Tavoil Company is produced by aeration at the bottom of the vacuum (
Raw material used to make bitumen which remains in the refinery vacuum distillation column) in the bitumen production unit. it is
The penetration rating (a measure of bitumen hardness) is between 60 and 70. Bitumen is specified by penetration and softening
point test. Designed for penetration range only. Penetration grade bitumen is thermoplastic, which leads to
The material softens at high temperatures and hardens at low temperatures. This unique temperature-viscosity relationship is
Important in determining performance parameters such as adhesion, rheology, durability and application temperature
asphalt.

Asphalt mode depends on temperature. Asphalt temperature vs. stiffness depends on the type of asphalt
Crude oil and its refining methods. Bitumen Penetration Grade 60/70 is a semi-hard penetration grade bitumen used as a paving grade
Bitumen suitable for road construction and repair. Also used in the production of asphalt pavements with the following properties
specifications. This grade of asphalt is mainly used in the manufacture of base and wear-resistant hot mix asphalt
training courses. Bitumen 60/70 is one of the most commonly used bitumen grades and it is the base material for all other bituminous products.
Needle Penetration determines the hardness of bitumen by measuring the depth of a standard loaded vertically with a needle
Penetrates within 5 seconds into a bitumen sample kept at a temperature of 25°C.

Bitumen Penetration Grade 60/70 Applications
Asphalt 60/70 is suitable for road construction and asphalt pavement with superior performance. the bitumen used
Used in the manufacture of hot mix asphalt for base and wear courses, the main use of this product is for mild roads
area. Bitumen is supplied during vacuum bottom oxidation pressing in bitumen production units. due to its medium
Blow to penetrate and use in mild areas.
