Penetration Grade Bitumen

Penetration Grade Bitumen is a standard bitumen usually used as a Paving Grade Bitumen essential for road construction and for the production of asphalt pavements with superior properties, and it’s very important once it bounds the aggregates and creates a unique cohesion and stability to the bituminous mix.

Viscosity Grade Bitumen

Viscosity Grade Bitumen (Asphalt) is a standard grade Bitumen usually used as a Paving Grade Bitumen suitable for road construction and for the production of asphalt pavements with superior properties. This grade of Bitumen is mainly used in the manufacture of hot mix asphalt for bases and wearing courses.

There are two methods of grading:

  • Standard Viscosity Grade Bitumen (AC-Grades), in which the Viscosity of the standard bitumen (asphalt) is measured at 60 ºC (140 ºF).
  • RTFOT Viscosity Grade Bitumen (AR-Grades), in which the Viscosity of bitumen (asphalt) is measured at 60 °C (140 °F) after the roll on thin film oven test.

Performance Grade Bitumen

 Performance Grade Bitumen, The Superpave Binder specification and the supporting test procedures are products of the Strategic Highway Research Program (SHRP), a 5-year research effort (1987 to 1992) which targeted $50 million for asphalt research.

PG system is based on project climate. The standard notation for PG binder is PG XX-YY where XX is the average-seven-day maximum pavement design temperature and YY is the minimum pavement design temperature

Emulsions bitumen prices


Bitumen emulsions are two-phased systems consisting of bitumen, water, and one or more additives to assist in formation and stabilization and to modify the properties of the emulsion.

 Bitumen emulsions can be divided into four classes. The first two are, by far, the most widely used:

· Cationic emulsions

· Anionic emulsions

· Non-ionic emulsions

· Clay-stabilized emulsions


Cutback Bitumen (Liquid Bitumen) is Bitumen that is dissolved in a solvent. Typical solvents include Naphtha, gasoline and kerosene, white spirit etc. The type of solvent controls the curing time while the amount determines the viscosity of the Cutback Bitumen.

Cutbacks are divided into three classifications:

Rapid-Curing (RC)

Medium-Curing (MC)

Slow-Curing (SC)

Oxidized Bitumen

Oxidized bitumen is mainly used for industrial purposes, such as roof insulation, flooring, industrial mastics, pipe coating, and paints. Oxidized bitumen is categorized based on softening points and penetration rate. For example, oxidized bitumen 85/40 is a type of bitumen whose softening point is 85±5 degrees Centigrade and its penetration rate is 40±5 dmm.

Polymer Modified Bitumen

Polymer modified bitumen (PMB) are mixtures produced from:  bitumen   polymers in which the polymers change the visco-elastic behavior of the bitumen and thus make this binder more suitable for different stresses.

The most commonly used polymer for bitumen modification is styrene–butadiene–styrene (SBS) followed by other polymers such as styrene–butadiene–rubber (SBR), ethylene–vinyl-acetate (EVA), and polyethylene. SBS block copolymers are classified as elastomers that increase the elasticity of bitumen. Although polymer modified bitumen costs higher than pure bitumen, they are considered to be more economical because of economic benefits of lower costs of road repairs.

Crumb Rubber Modified Bitumen (CRMB)

Crumb Rubber Modified Bitumen (CRMB)

CRMB is a high performance Crumb Rubber Modified Bitumen manufactured using finely powdered scrap tyre rubber and processed in a sophisticated reactor at high temperatures. Complex processing modifies the properties of Bitumen and imparts additional strength, elasticity and other beneficial properties to make it better able to withstand high traffic loads, extreme weather conditions and other forms of stress. Use of CRMB leads to excellent pavement life, driving comfort and low maintenance
