Oxidized Bitumen-Based Sealant for a Range of Applications

SEALING APPLICATION OXIDIZED BITUMEN 115/15

A form of bitumen-based sealant, blown or oxidized bitumen grades are produced by passing air through soft bitumen under controlled temperature conditions. This process gives the bitumen more rubbery properties than penetration or hard grade bitumen, and they have a variety of uses in industrial applications. The rubberized bitumen allows for water resistance and added durability, providing better performance as an asphalt crack sealant.

Uses of Oxidized Bitumen-Based Sealants

RUA Asphalt sealant 115/15, known as oxidized bitumen or blown asphalt, is used for crack sealing, joint sealing, and other industrial applications. The softening point of oxidized bitumen is much higher than standard bitumen, causing lower thermal sensitivity. This makes using bitumen sealant for concrete joints an effective solution for a variety of purposes, like home or building roof insulation, flooring repairs or renovations, and pipe coating, among other applications. As a joint sealant and crack sealant, it is also utilized in automobile manufacturing and the piling industry.

Properties of Oxidized Bitumen

RUA Oxidized bitumen is a very flexible, chemically stable, and durable compound that is also completely water-resistant. Additionally, Oxidized Bitumen has some very prominent technical advantages that make it a very sought-after compound in various applications. Asphalt sealants are offered in either 20kg or 25kg boxes.

How Oxidized Bitumen is Used in Repairing Cracks

Oxidized or rubberized bitumen is widely used in various industries because of the properties that make it a great joint sealant. This grade of bitumen has a higher softening temperature compared to standard ones. Because of this, oxidized bitumen can create a seal that withstands high temperatures without bleeding.

One of the most well-known uses of rubberized bitumen is preventing and curing any types of cracks on roads. Whether reflective, thermal, or fatigue cracking, oxidized bitumen can be used to address the problem.

When an asphalt pavement develops cracks, it can pose various safety hazards to pedestrians and motorists. Cracks create an uneven surface that may trip and injure people walking on the surface. They may also cause drivers to lose control of their vehicles, which then puts them at risk of colliding with other cars, people, or objects.

To start the repair of cracks on an asphalt pavement, vegetation, dirt, and debris should be removed from them. This is done to ensure that the rubberized bitumen can flow into the cracks and adhere to their sides. The cleaning process can be completed using mechanical wire brushes and routers.

Next, the joint sealant should be pumped directly into the cracks with an oil-jacketed kettle, a crack banding machine, or a pour pot. A hot pour material like oxidized bitumen can be applied in lower temperatures. It should then be allowed to cool for 15 to 20 minutes before opening the repaired road to traffic.
