Oxidized Bitumen Usage

Oxidized Bitumen, Blown Asphalt high softening temperatures qualify them as the excellent sealant for prevention from bleeding in high-temperature applications.

Oxidized Bitumen Uses

The most popular grades are; grades 95/25, 85/25, 90/40, and 115/15. We are also capable of producing other grades of Blown Bitumen upon request by our customers. Oxidized Bitumen high softening temperatures qualify them as the excellent sealant for prevention from bleeding in high-temperature applications.

Blown Grade Bitumen shall be broken up into small pieces (for the blown grade in molded cake form) and heated slowly to the application temperature of 220ºC to 230ºC.

Oxidized Bitumen is predominantly used in the piling industry as an anti-slip compound for the manufacture of undercarriage sealants in the automobile industry.

It is also used as a sealant compound, as a joint filling compound apart from being used in the manufacture of roofing felts and sound dampening felts. Further, Oxidized Bitumen is used in the manufacture of bituminous marine mastic, which is required for the oil and gas pipeline joints.

This Oxidized Bitumen is available in different grades like 95/25, 85/25, 75/25, 90/40 and 115/15. Oxidized is also capable of producing other grades of Oxidized Bitumen according to the specifications of individual clients

Usage of Oxidized Bitumen : Blown Asphalt Uses

Blown Asphalt Grades are suitable for sealing saw cuts and joints where there is expected to be the minimum amount of moving in the joint. Their wide temperature range prevents bleeding in high-temperature applications. Oxidized bitumen can also be used in industrial applications like roofing, flooring, mastics, pipe coatings, electrical applications to name a few.

Oxidised bitumen ” Oxidized Bitumen, Oxidized Asphalt, Blown Asphalt ” range is used in the waterproofing industries, for carpet-backing, corrosion protection, acoustic panels and the manufacture of paints, amongst other applications.

Air-blowing:

The manufacturing process used to make oxidized roofing asphalts in which air is blown through an asphalt flux. An exothermic oxidation reaction occurs, yielding an asphalt that is harder, more viscous, less volatile, and less temperature-susceptible than the asphalt flux used as the feedstock to the process.

Asphalt, oxidized (blown or air-refined):

Asphalt treated by blowing air through it at elevated temperatures to produce physical properties required for the industrial use of the final product.

Blown Asphalts are used in roofing operations, pipe coating, undersealing for Portland cement concrete pavements, hydraulic applications, membrane envelopes, some paving-grade mixes, and the manufacture of paints.

Applications of Bitumen 60/70, Penetration Asphalt, Blown Asphalt Production Process, Oxidized Bitumen Usage,

Blowing still:

Closed-process vessel fitted at its base with a sparger and used in the air-blowing process to make many types of roofing asphalt.

Coating asphalt:

An air-blown or Blown Asphalt uses to manufacture roofing materials used in a variety of roofing systems such as asphalt shingles, polymer-modified bitumen roofing, reinforcing and underlayment felts, and roll roofing products.

Modified bitumen:

A roofing system based on membranes manufactured by impregnating or coating one or more fabric plies with a straight-run or oxidized asphalt modified using a polymer, usually atactic polypropylene (APP) or styrene-butadiene-styrene (SBS). Modified bitumen systems may be torch-applied or installed by adhesion in hot asphalt or a cold-applied, solvent-based asphalt adhesive (cutback asphalt). Modified bitumen systems are used on low-slope (primarily commercial or industrial) roofs.
