CUTBACK MC250-Cutback bitumen
$0.00Bitumen is ‘cutback’ by adding controlled amounts of petroleum distillates such as kerosene. This is done to reduce the viscosity of the bitumen temporarily so it can penetrate pavements more effectively or to allow spraying at temperatures that are too cold for successful sprayed sealing with neat bitumen.
CUTBACK MC250-Cutback bitumen
$0.00Bitumen is “cutback” by adding controlled amounts of petroleum distillates, such as kerosene. Type and quality of Cutback depends on type and amount of solvent in the pure bitumen. The more solvent in Cutback bitumen, leads to the more viscosity in bitumen. Cutback bitumen is used when there is limited access to heating equipment, bitumen decomposition in high temperature, bitumen cooling throughout working, workers safety, fire and time consuming. This type of bitumen is used in road operations for surfacing and pavement. Medium-Curing (MC) bitumen is achieved from solving pure bitumen into kerosene.
Cutback bitumen is classified based on viscosity grade. It is divided into three categories:
Rapid-Curing (RC)
The cutback bitumen is known as rapid-curing (RC) if the bitumen is solved in gasoline. The reason is that evaporation occurs quickly and the bitumen is deposited. RC cutbacks are divided into RC250, RC70, RC800 and RC3000 categories. The numbers indicate the viscosity of bitumen. Naphtha could be mixed with bitumen 80/100 for more dilution.
Medium-Curing (MC)
MC cutbacks are prepared by solving bitumen in kerosene which evaporates more slowly than gasoline. MC cutbacks are divided into five groups with their viscosity varying from 3-4 to 6,000 at 60 degrees Centigrade. This kind of bitumen may be achieved by solving bitumen 85/100 in Kerosene.
Slow-Curing (SC)
Slow-curing cutback may be achieved from solving bitumen in gasoil or fuel oil or directly from distillation of crude oil. SC cutbacks do not evaporate under normal weather conditions, but they gradually experience changes in their molecular form. This kind of bitumen is achieved from solving bitumen 85/100 in heavy solvent such as Gasoil or Fuel oil which will not only evaporate but also make it hard. Types of this kind of bitumen includes SC 70, SC 250, SC800 and SC 3000.
CUTBACK MC30-Cutback bitumen

CUTBACK MC3000-Cutback bitumen
$0.00Bitumen is ‘cutback’ by adding controlled amounts of petroleum distillates such as kerosene.

CUTBACK MC70-Cutback bitumen
$0.00Bitumen is ‘cutback’ by adding controlled amounts of petroleum distillates such as kerosene. This is done to reduce the viscosity of the bitumen temporarily so it can penetrate pavements more effectively or to allow spraying at temperatures that are too cold for successful sprayed sealing with neat bitumen.

Base on the time of curing after spraying, Cutback bitumen classification as Rapild Curing(RC), Medium Curing (MC) and Slow Curing (SC)
Penetration Grades
$0.00In the past, the penetration index was defined based on the assumption that thermal sensitivity in the bitumen used in road construction was zero. Bitumen is a thermoplastic material, meaning that it becomes pliable or moldable above a specific temperature and returns to a solid state upon cooling.
Penetration-grade bitumen is mainly used in road surfacing. Bitumen with lower penetration grade is used in the regions with warm climate while higher penetration grade is used in colder weather.
Pasargad Oil Company is capable of producing different grades of road surfacing bitumen in compliance with national and international standards in its six plants located at Tehran, Tabriz, Arak, Shiraz, Bandar Abbas, and Abadan refineries. Penetration rate bitumen is graded based on penetration and softening point tests. This table describes the physical properties of penetration-grade bitumen based on European standards. Penetration-grade bitumen is mainly used in road construction. During the last two decades of the 20th century, most road construction projects showed inclination for solid bitumen which results in more effective asphalt.
Performance Grade
$0.00Performance Grade Bitumen is the Latest Standard of bitumen. It is new method bitumen standard which based on varying temperatures. This method studies the mechanical specifications of bitumen. Since in this method, a temperature range is defined for bitumen, the consumer can easily choose the desired product. Performance Grade determined for polymer modified bitumen and pure bitumen based on environmental conditions and temperature. The wider PG Grades Range the higher resistance and more favorable specifications.
Performance Grade (PG)-Bitumen & Tar
$0.00From October 1987 to March 1993, Strategic Highway Research Program (SHRP) was conducted in the United States. The program was focused on the development of new methods for assessing the performance of bitumen binders. The research resulted in the development of a new method known as Superior Performing Asphalt Pavements (Superpave).
The main specifications of this method included:
Using the efficiency criterion for bitumen binders and asphalt concrete
Considering climatic conditions in application of bitumen
The problems studied in this method are as follows:
Winter low-temperature bitumen cracking not related to loading
Bitumen fatigue cracking due to loading
Summer high-temperature bitumen deformation due to loading
The primary objective behind determining the new specifications was to facilitate the purchase of bitumen products of better quality because these specifications will clearly describe the product for potential buyers. The new specifications also guarantee the proper performance of bitumen in coating. Climatic conditions are important factors in the efficiency of coating, but limited research has been conducted on this issue due to limited time and quite similar weather conditions. Moreover, they would not be precise if the loading factor is not taken into consideration. The producers all around the world, has been started to produce this type of bitumen which POC is a prominent in this regard. Having installed SHRP systems, Pasargad Oil Company is capable of selling bitumen to its customers based on PG method. It worth to remind that in the past, penetration was used as a factor for bitumen grading. In performance grade, the focus is on the mechanical specification of bitumen while in penetration grade, experimental parameters are involved. In Iran, pen-grade is more common, but in some cases, PG has better be used for a better performance. 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.
VG Bitumen-Bitumen & Tar
$0.00Bitumen 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 Centi Stokes. Pure bitumen has been graded based on AASHTO-M226 and ASTM-D3381 standards. Tables 1-1 to 1-6 indicate tests and criteria.
