Bitumen 70/100 Description
Bitumen Penetration Grade 70/100 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 HJ Oil is petroleum grade bitumen, manufactured from fractional / vacuum distillation of crude oil. The Bitumen supplied by HJ Oil is produced from vacuum residue (short residue) feedstock. Penetration Grade bitumen are specified by the penetration and softening point test. The designation is by penetration range only. The penetration grade bitumen 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.
Penetration Bitumen 70/100 is manufactured with selected crude oils inefficient production processes that are undertaken in accordance with quality management standards EN ISO 9001. The consistently high quality is based on the meticulous selection of raw material and careful processing.
Constant quality control and additional comprehensive tests ensure the unproblematic use of Bitumen 70/100 in the asphalt mixing plant.
Properties of Bitumen 70/100
Penetration grade bitumen 70/100 supplied by HJ Oil is pure petroleum grade bitumen, manufactured from vacuum bottom by passing hot air. The bitumen supplied by HJ Oil is produced from remain of crude oil after cracking and removing hydrocarbon. bitumen 70/100 has penetration between 70~100 desi-millimeter and the softening point between 42~ 52 C.
The penetration bitumen 70/100 has a thermoplastic property which is like synthetic resin material which gets softer with heating and hardens when cooled. Penetration grade bitumens are specified by the penetration and softening point test. The temperature-vs-stiffness relationship of bitumen is dependent on the source of crude oil and the method of refining.
Bitumen 70/100 is penetration bitumen using as paving bitumen suitable for road construction and repair also for the production of asphalt pavements with below technical specifications.
Application of Penetration Grade Bitumen 70/100
The bitumen 70/100 is a semi-hard penetration grade, with penetration between 70 and 100. Which is mostly used in road construction, asphalt pavement, and manufacturer of hot-mix asphalt.
Also 70/100 Penetration Grade Bitumen is used in the construction of single seals, double seals, and Cape seals, either as a tack coat or penetration spray. It is also used as the base bitumen for the manufacture of the majority of emulsions and polymer modified binders.
PAVING GRADE BITUMEN 70⁄100 satisfies the requirements of fatigue resistance and provides very high performance in terms of plasticity and behavior at low temperatures.
The optimum viscosity in the range of temperatures for mixing and laying guarantees easy workability of the products, even for high-stress conditions.
PAVING GRADE BITUMEN 70⁄100 is used to produce bituminous mixes constituting a flexible structure for the paving of roadways, runways, pavement, track race, and landing platform.
Guaranty and Safety of Penetration Grade Bitumen 70/100
HJ Oil guaranty the quality of bitumen penetration grade 70/100 with the arrangement of the international inspectors to check the quality and quantity of the penetration grade bitumen 70/100 during the loading to the vessel and controlling the production by QC by batch test report before shipping.
HJ Oil guarantees that the Bitumen Grade 70/100 is produced in compliance and conformity to International of European Standard DIN EN 12591:99, also meets the requirements of the following specification.
Bitumen 70/100 Packing
Paving Bitumen 70/100 is commonly packed in new steel drums, 150, 180 & 220 Kg barrels, and 1MT and 500Kg Jumbo Bags or 300kg Bitubag.
Likewise, the rest of the grades are ready to load Ex-work bulk by truck.
