Bitumen

Bitumen Bitumen is primarily used to pave roads. It is a brown or black mixture of hydrocarbons, which is derived from petroleum. The consistency of bitumen varies from viscous to solid, and in its solid form, it is commonly known as asphalt.

Product description

Performance Grade (PG)

PG is the latest standard of the day. This relatively new method classified bitumen is based on varying temperatures. It is a fully scientific method studying the mechanical specifications of bitumen. In this method, a temperature range is defined for bitumen and the consumer can easily choose the desired product.

Having installed SHRP systems, Pasargad Oil Company is capable of selling bitumen to its customers based on PG method.

Today, a PG is defined for polymer modified bitumen and pure bitumen based on environmental conditions and temperature. A wider PG range means higher resistance and more favorable specifications. Pasargad Oil Company has the capacity to produce all these grades. This company first conducted climate zoning in Iran to specify the appropriate bitumen for different geographical zones.

· Viscosity Grade

Bitumen is graded based on absolute viscosity at 60 ºC or kinematic viscosity at 135 ºC. The SI physical unit of dynamic viscosity is Poise and kinematic viscosity is expressed in CentiStokes. Pure bitumen has been graded based on AASHTO-M226 and ASTM-D3381 standards.
