Straight Run Bitumen – A Standard Base for Road Construction and Civil Engineering Projects
Straight Run Bitumen refers to bitumen obtained directly from the distillation of crude oil in a refinery distillation tower, without undergoing any additional chemical treatment or modification.
This is the most basic and widely used form of bitumen in road construction and asphalt production, and it also serves as the primary raw material for manufacturing various grades of modified bitumen.
Specifications of Straight Run Bitumen
Straight run bitumen is classified in two main ways:
1. Penetration Grade Bitumen
Classified according to the penetration depth of a standard needle under specific temperature and loading conditions. Numbers such as 60/70, 80/100, or 40/50 indicate the hardness or softness of the bitumen.
Examples:
60/70 – The most common grade for road construction in temperate climates
80/100 – Suitable for cold climates
40/50 – Ideal for projects requiring higher resistance to heat
2. Viscosity Grade Bitumen (VG)
Classified based on viscosity (flow resistance) measured at specified temperatures (e.g., 60°C and 135°C).
Examples:
VG-10 – Suitable for asphalt work in cold climates
VG-30 – Ideal for highways and warmer regions
VG-40 – Designed for heavy traffic load applications
Applications of Straight Run Bitumen
Hot mix asphalt production for roads, airports, and urban streets
Construction of various pavement layers (base and wearing course)
Raw material for producing emulsion bitumen, oxidized bitumen, and polymer-modified bitumen
Export supply to countries requiring base-grade bitumen
