Bitumen Penetration Grade 60/70

Bitumen Penetration Grade 60/70

This grade of bitumen is mainly used in the manufacture of hot combine asphalt for bases and wearing courses. Bitumen 60/70 is the most used bitumen grade and basic material for all alternative bituminous products.

Bitumen Penetration Grade 60/70 is commonly used to manufacture asphalt mixes, bitumen emulsion, cut-back bitumen, and modified bitumen. Bitumen 60/70 has the highest-boiling point, heaviest and most polar fraction from the vacuum distillation of crude oil. Bitumen 60/70 is composed of asphaltene and maltene. The heavy insoluble asphaltene molecules give bitumen 60/70 its body and softening point while the maltenes are oily and make asphalt flexible. Asphaltene molecules are soluble in aromatic solvents like toluene but insoluble in heptane.

The maltenes are heptane-soluble molecules and less aromatic. Penetration grade bitumen supplied by Visagie is pure petroleum grade bitumen, manufactured from vacuum bottom by passing hot air. The bitumen supplied by Rahaoil 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 the softening point between 49 ~ 56C. 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.

Here are some key properties of Bitumen Penetration Grade 60/70:

Penetration: The “60/70” in the name refers to the penetration range of the bitumen. Penetration is a measure of the consistency or hardness of the bitumen. Bitumen 60/70 has a penetration value between 60 and 70 decimillimeters (0.1 mm) when tested using a standard penetration test.

Viscosity: Bitumen 60/70 has a relatively moderate viscosity. Viscosity refers to the thickness or flow resistance of the bitumen at a given temperature. It should be fluid enough to be mixed and applied easily during construction but also maintain stability under traffic loads.

Softening Point: The softening point of Bitumen 60/70 is the temperature at which it becomes soft enough to allow penetration by a standard needle. This property is important for determining the temperature susceptibility of the bitumen and its performance in different weather conditions.

Ductility: Ductility is the ability of bitumen to stretch without breaking. Bitumen 60/70 should have sufficient ductility to withstand the deformation caused by traffic loads and temperature fluctuations without cracking.

Flash Point: The flash point is the lowest temperature at which bitumen vapors can ignite when exposed to an open flame or spark. It’s an important safety consideration during storage, transportation, and application of bitumen.

Solubility: Bitumen 60/70 should have a specific solubility in trichloroethylene or another suitable solvent. Solubility can indicate the purity of the bitumen and its compatibility with other materials used in road construction.

Density: Density is the mass per unit volume of the bitumen. It affects the overall weight of the asphalt mixture and can influence its mechanical properties.

Adhesion: Bitumen 60/70 should exhibit good adhesion to aggregates (such as stones and sand) to form a durable asphalt mixture. Adequate adhesion ensures that the road surface remains intact under the stresses of traffic.

Rheological Properties: Bitumen 60/70’s rheological properties, such as its elastic and viscous behavior under different temperatures and stress conditions, are important for predicting its performance in various climates and traffic conditions.

Oxidation Resistance: This property relates to the bitumen’s ability to resist oxidation and aging due to exposure to air, sunlight, and other environmental factors. Oxidation resistance contributes to the longevity of the asphalt pavement.

Uses of Bitumen Penetration Grade 60/70

Bitumen penetration grade 60/70 it is the most common grade of bitumen
The penetration grade bitumen’s have a thermoplastic property that causes the material to soften at high temperatures and to harden at lower temperatures. This unique temperature/ viscosity relationship is important once determining the performance parameters which is using in worldwide bitumen market as an adhesive, joint sealant, waterproofing agent, damp proofing, construction and maintenance of the road, airfields and all area of and pool lining, soundproof and acoustic, pipe coating and paing along with other thousands application with below technical specification. this grade of bitumen is mainly used in the manufacture of hot mix asphalt for bases and courses.

The most common grade is bitumen 60/70 which can be used for many applications. The penetration bituminous asphalt with high penetration numbers which are soft, mostly used in cold weather conditions and hard bituminous asphalt (low penetration number) can be used for warm weather conditions.
