Quick & Informative Guide To Bitumen Grade 60.70

Posted by Claire Smith on December 21st, 2020

The bitumen grade 60.70 is a kind of semi-hard penetration grade which is used as paving grade bitumen that is frequently used for road construction, and it is conjointly used for producing asphalt pavements with less technical specifications.

Also, this bitumen grade 60.70 is commonly used for manufacturing hot combined asphalts for wearing courses and bases. Also, it’s a highly basic material for all rare bituminous products.

Properties of Bitumen 60/70

The bitumen penetration grade 60.70 is often used for manufacturing bitumen emulsion, cut-back bitumen, asphalt mixes, and modified bitumen. This penetration grade features the highest-boiling point and has the heaviest, yet most polar fraction from a vacuum distillation of crude oil. Bitumen 60.70 comprise of maltene and asphaltene

If we talk about highlighting the properties of this bitumen 60.70, then it’s known for featuring heavy insoluble asphaltene molecules. This gives bitumen 60.70 its body, and mellowing point, while, maltenes are slick, and make black-top more adaptable.

Asphaltene molecules on other hand get easily soluble in aromatic solvents such as; toluene, but not soluble in heptane. The maltenes are less aromatic and soluble in heptane

If you ever consider buying Penetration grade 60.70 from any reputable and leading source, then you’ll learn it’s pure petroleum grade bitumen that is made from vacuum bottom by passing hot air. The bitumen is produced from leftover crude oil after cracking, and by removing hydrocarbon.

The entry-level grade bitumen 60.70 has a thermoplastic property that resembles engineered sap material that gets gentler with warming and solidifies when cooled. This evaluation of bitumen 60/70 has an exceptionally solid thickness contrast with different evaluations.

Uses of Bitumen 60/70

The infiltration bitumen grade has a thermoplastic property which mellow material at high temperatures and solidifies material at decreased temperatures

This bitumen grade is frequently used in the making of hot mix asphalt for courses and bases

This is the most common grade of bitumen which is used for plenty of applications. The soft penetration bituminous asphalt is mostly used in cold weather conditions, and hard bituminous asphalt (low penetration number) and suitable to use for warm weather conditions as well
