Oxidized bitumen comply with International Standards. Oxidized bitumen has got a range of uses. It can be used in industries as an adhesive, protective coating, bonding agent, electric insulator and stcuctures below ground. Because of their softening point, it shows excellent physical stability, no exudation or bleeding in contact with highly absorbitive material and a remarkable resistance against atmospheric corrosion. Grades of Oxidized Bitumen:
85/25, 85/40, 90/15, 115/15, 135/10, 155/6
ANTI STRIPPING AGENT is a highly stable anti stripping agent for increasing adhesion between asphalt and aggregates. It has been specifically designed for use in the manufacture of high performance emulsions, Cutbacks and hot mix. It may be used in polymer asphalt systems. It is NOT an amine and so is also useful as a bitumen additive.
Anti Stripping agent is ‘Heat Stable’ for 10 days at 1600C It has no smell, non flammable, and contain no volatile solvents. It is liquid in nature and easy to use. It’s USE is recommended to avoid stripping even under submergence in water.
CUTBACK BITUMEN is a low viscosity, cold applied bituminous primer. Cutback Bitumen is produced by fluxing bitumen with distillates of petroleum for use in road construction. A bituminous prime coat is an initial application of low viscosity liquid material to an absorbent surface preparatory to any super-imposed treatment or construction. The object of priming is to promote adhesion between the existing surface and super-imposed treatment or construction. The choice of a bituminous primer shall depend upon the porosity characteristics of the surface to be primed. Cutback bitumen Primer is classified into Rapid Curing (RC), Medium Curing (MC) & Slow Curing (SC) based on viscosity.
Paving Bitumen shall be prepared by the distillation of suitable crude, petroleum oil without subsequent blending with other grades. The material shall be homogenous and shall not foam when heated to 175 deg C. No mineral matter other than naturally contained in the material shall be present.
Paving Bitumen (Straight Grade) used in construction and maintenance of Roads, Airfields & Allied Constructions.
CRMB is a blend of selected grades of bitumen and crumb rubber modifier. The modifier restores the required visco-elastic balance of the Bitumen binder, which improves binder resistance to any form of permanent deformation while maintaining high resistance to fatigue, thermal and low temperature cracking. When using CRMB, the maintenance free life of pavement will increase one and half to two times as compared to roads built using unmodified neat bitumen binders. CRMB has good adhesion to different types of aggregates which therefore reduce, rutting, cracking, deformations, etc. CRMB meets the performance- based specification of IRC: SP 53-2002.
» Excellent Resistance to Thermal and low temperature cracking.
» Superior resistance to any form to permanent deformation.
» Better adhesion between aggregate and binder.
» Overall improved performance in extreme climatic conditions.
» Higher fatigue life of mixes.
» Highly flexible and stability
» Cost effective.
This invention relates to the process for the preparation of a polymer and rubber based modified binder which is useful for the construction of roads catering to heavy traffic and also for the formation of airfields and surfacings, besides its use as binder for stress absorbing membrane (SAM) and stress absorbing membrane interlayer (SAMI) for sealing of cracks, preventive maintenance of flexible pavement and delaying reflective cracking. Modified Bitumen performs better than ordinary Bitumen in high rain fall area and in situation where the aggregates are prone to stripping.
» Improves resistance in cracking resulting in stronger and more durable overlays even in extreme climatic conditions.
» Reduces deformation on the roads even at temperatures of ( 50-70 degrees C)
» Polymer and Rubber based modifer binder extend life of pavement by 50-70% compared to conventional bitumen.
» PMB act as a multigrade bitumen and are economical when life cycle cost is taken into consideration.
A reliable and efficient supplier is often the difference between success and failure in most projects.

DID YOU KNOW
The use of bitumen with natural asphalt or mixtures for waterproofing and as an adhesive dates back to the fourth millennium B.C., when the Sumerians used it in statuary, mortaring brick walls, waterproofing baths and drains, in stair treads, and for ship building.
