Bitumen penetration grade 60\/70 means the penetration value is in the range between 60 to 70 mm\/10 at standard test conditions which commonly used as a paving grade. This bitumen is produced through aeration on vacuum bottom (the raw material used for making bitumen left in vacuum distillation column in oil refineries) in bitumen production units. Its penetration grade ( the measure of bitumen hardness) is between 60 to 70. Bitumen is specified by the penetration and softening point test. Designing 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.
\nThe Bitumen mode is dependent on temperature. The temperature-vs-stiffness relationship of bitumen is dependent on the type of crude oil and its refining method. Bitumen penetration grade 60\/70 is semi-hard penetration grade bitumen used as a paving grade bitumen which is suitable for road construction and repair. It is also used for the production of asphalt pavements with the below technical specification. This grade of bitumen is mainly used in the manufacturing of hot mix asphalt for bases and wearing courses. Bitumen 60\/70 is one of the most used bitumen grades and it\u2019s a basic material for all other bituminous products.
\nPenetration determines the hardness of bitumen by measuring the depth to which a standard loaded the needle will vertically penetrate in 5 seconds, in a sample of bitumen maintained at a temperature of 25 degrees Celsius.<\/p>\n

applications<\/span><\/h2>\n

Bitumen 60\/70 is suitable for road construction and for the asphalt pavements with superior properties. This type of bitumen used in the manufacturing of hot mix asphalt for bases and wearing courses and the main usage of this product is used in the road in mild regions. The bitumen is provided during the presses of oxidation of vacuum bottom in bitumen production units. Due to its medium air blowing and penetration, it is used in mild areas. Bitumen babaei\u2019s bitumen 60\/70 is fully qualified and guaranteed through the expertise of our international inspectors to ensure the quality meets the industry standards. Bitumen Babaei\u2019s bitumen is guaranteed to meet ASTM standard.<\/p>\n

Specification<\/span><\/h2>\n

Softening point and penetration of bitumen 60\/70:<\/strong>\u00a0Penetration grade bitumen supplied by ATDM is pure petroleum grade bitumen, manufactured from vacuum bottom by passing hot air. The bitumen supplied by ATDM is produced from remain of crude oil after cracking and removing hydrocarbon. Penetration grade bitumen 60\/70 has penetration between 60~70 desi-millimeter and softening point between 49 ~ 56 C. The penetration grade bitumen 60\/70 has a thermoplastic property which is like as synthetic resin material which gets softer with heating and hardens when cooled. This grade of bitumen 60\/70 has very strong viscosity compare to other grades.
\nGuaranty\/warranty of bitumen 60\/70:<\/strong>\u00a0ATDM guaranty the quality of bitumen 60\/70 with arrangement of international inspector to check quality and quantity of the bitumen during the loading to vessel and controlling the production by QC by batch test report before shipping. ATDM guaranty the quality to meet with ASTM\/EN 12591.<\/p>\n\n\n\n\n\n\n\n\n\n\n\n\n\n
