Penetration Bitumen
Penetration Bitumen is a compound obtained from the heaviest cut of crude oil. This black compound is prepared in solid and semi-solid form, with natural origin or produced in oil and gas refineries and will be offered in the consumer market. This crude oil-derived compound contains a large number of high molecular weight hydrocarbons, asphaltene, resin, heteroatoms and metals such as vanadium, nickel and iron. The most common use of this elastic compound is in the construction industry, the production of waterproofing, the production of some chemical compounds and most important use in the road and road construction industry, and in combination with sand, as asphalt for repair, renovation and road construction. Intercity and intercity will be used.
Penetration Bitumen grading system
Penetration Bitumen grading was proposed to determine the consistency and stability of semi-solid bitumen and was formally implemented in the early nineteenth century using specialized laboratory methods. This grading is performed according to this criterion in order to determine the penetration rate and softening point of bitumen resulting from distillation, oxidation, heat failure, aeration and sedimentation processes and provides consumers with a general classification of types.
Test
Penetration Bitumen experiments and methods performed to determine the degree of hardness of blown bitumen (term oxidized) and pure bitumen, to facilitate the naming and application of bitumen in quality control laboratories of oil and gas refineries and in pure bitumen, determine the degree And the degree of permeability, and in blown bitumens, in addition to determining the degree of penetration, will also determine the degree of softness of the bitumen.
Defining degree
Penetration Bitumen, according to the laboratory definition, the degree of penetration of bitumen is the longitudinal value (in millimeters) that a standard laboratory needle penetrates into bitumen at a temperature of 25 degrees Celsius in 5 seconds, with a pressure of 100 grams.
Using in asphalt
The most important and main applications, especially blown bitumen, is in the road and road construction industry to produce asphalt for repair, renovation and establishment of road routes. According to the agreements obtained from the laboratory results, determining the degree of penetration of bitumen, with a degree of penetration between 80 and 85, in the preparation of asphalt concrete and with a degree of penetration greater than 85, in the preparation of macadam bitumen and cold asphalt Will be used.
