BITUMEN- (Paving & Industrial)
In Conform to IS: 73 & IS: 702

Bitumen is the end product of distillation petroleum crude. The residue obtained from the refineries is called straight grade bitumen. This bitumen has a softening point much below the day temperature and penetration of 80 to 100 or 60 to 70, and is supplied by refineries.

The straight grade bitumen obtained from the refineries is processed in our highly modernized plant through exothermic reaction, by simultaneously heating and blowing to the relevant time limit required for the exact grades depending upon its end- use. By this process Bitumen becomes sludge/moisture free and softening/penetration values are improvised to great extent. This is called Blown Bitumen and the same has a wide range of industrial applications.

Blowing grades are divided into two categories namely Paving grades confirming to IS: 73 and industrial grades confirming to IS: 702. These grades are further distinguished depending upon their softening points and penetration values.

(Bitumen Impregnated, Resilient Type, Performed Fillers for Expansion Joints in concrete Structures)

Construction of concrete roads, runways, floor and roof slabs of buildings, involves the casting of concrete in slab form. This leads to construction joints. Bituminous expansion joint board is a low density fiber board impregnated with bituminous solutions which are light and rot-proof. Provision of these boards in the joints permits free movement of the concrete slabs contract, this prevents damage to the slabs besides waterproofing and resisting entry of foreign matter into the joints.
Bituminous expansion joint boards are available in thickness of 12mm (1/2”), 18mm (3/4”) and 25mm (1”) thickness.


• It preserves the life and evenness of the slab.
• It prevents seepage of surface water through the joints and also prevents ingress of water or dirt down the joints.
• Permits free movement of the concrete slabs.
• Absorb ground shocks, caused by vibration and relaxes the stress of the concrete slabs.
• Relieves stresses developed due to temperature shrinkage, creep, relaxation, variation, etc.

The Bitumen Binder which are used in road construction are quite Viscous, Semisolids at the normal temperature. They have to be heated up to liquid state, to retain the fluidity. Some times it becomes inconvenient to heat it, hence in most European countries it is prohibited. Thus Bitumen Emulsion was used as the most competitive medium for applying Bitumen to road surfaces or as base courses. Use of emulsion, facilitates not only fluidity at the atmospheric temperatures, but also the application to damp road surfaces and wet aggregates.

Emulsified Bitumen acts as a key tool in road maintenance and construction technology as it combines amazing versatility while offering multiple comparative advantages.

Types of Emulsified Bitumen:

Bitumen Emulsion is of three types. Cationic, anionic and Non-ionic types. The choice of particular type of emulsion depends upon the climatic condition, aggregates and the soil condition.

Cationic Emulsion:

This represents more than 95% of the world consumption today. These cationic types as per industry standards, are used in three grades.



Applications: surface Treatment, tack coating, grouting, penetration macadam.


Applications: pot hole Repair, Patch Work, Surface Dressing, Plant Road Mixes, Course aggregate for Premix Carpet.


Applications: Slurry seat, cold mixes, fog seal, crack filling.
