Hard bitumen 85/40 150/5

When the oxidation of bitumen occurs in the presence of catalytic agents , the process is called catalytic oxidation . By the action of catalysts the reaction rate is changed, allowing the oxidation process is faster and more homogeneous throughout the bulk form , in addition to allowing greater process control and final product with different penetration like hard asphalt 115/15 which is 115 is softening point and 15 is penetration.

Depending on the purpose for which it is the oxidized asphalts may also receive different types of polymer additives, in order to increase its plasticity, stickiness, resistance to weathering and oxidation.


Bitumen Penetration Grades include 40/50, 60/70, 80/100, 85/100

Also known as paving grade bitumen, PEN grades are classified based on the depth to which a certain laboratory needle penetrates them during a penetration test, indicating their hardness. Higher figures denote softer bitumen, indicating deeper penetration, while lower figures signify harder bitumen with shallower penetration. For example, in bitumen 60/70, the first number represents minimum penetration, and the second represents maximum penetration. Common bitumen PEN grades include 40/50, 60/70, 80/100, and 85/100. Among these, bitumen 85/100 is the softest, while bitumen 40/50 is the hardest

viscosity grade

Viscosity Grade Bitumen VG 10, VG 20 , VG 30, VG 40, VG50 and VG 60

Viscosity grade bitumen, a vital ingredient in road construction, comprises various subgrades tailored to specific project needs. These subgrades, such as VG 10, VG 20, VG 30, VG 40, VG 50, and VG 60, classify based on their viscosity characteristics at defined temperatures. VG 10 and VG 20 serve low to moderate-traffic roads, while VG 30 suits highways and urban areas.

Polymer Modified Bitumen

In road construction, engineers actively utilize Polymer Modified Bitumen (PMB), a versatile binder renowned for its enhanced properties over conventional bitumen. Manufacturers produce it by blending bitumen with polymer additives, which actively improve its durability, resistance to rutting, cracking, and fatigue, particularly in challenging environmental conditions.. PMB’s superior performance makes it ideal for high-stress applications, such as heavy traffic roads, airports, and highways. When applied to the subgrade, PMB forms a robust bond, enhancing the overall stability and longevity of the pavement structure. This results in reduced maintenance needs and prolonged service life, ensuring safer and more sustainable transportation infrastructure


Bitumen Performance Grade PG 64-22 PG76-22 PG -64-28 PG 58-34 PG 82-22 PG 76-28 PG 70-28 PG 64-22 PG 70-22

Bitumen Performance Grade (PG)  is a classification system that defines the temperature range within which a particular grade of bitumen maintains its performance characteristics. It categorizes bitumen based on its viscosity at high and low temperatures, offering a more precise specification compared to conventional grading systems. PG grades ensure that bitumen can withstand the diverse climatic conditions and traffic loads experienced on roads. When applied to the subgrade, bitumen PG forms a crucial component of pavement layers, providing stability, flexibility, and resistance to deformation. This helps to mitigate cracking, rutting, and other distresses, thereby prolonging the lifespan of the pavement structure and ensuring safer and smoother roads for motorists.
