ProductsPAVING GRADE BITUMEN
Bitumen is the end product in the crude distillation process. This raw bitumen is called Straight grade bitumen and has penetration values of 200-300. The straight grade bitumen obtained from the refineries is processed in our highly modernized plant through the exothermic reaction, to the relevant time limit to produce the desired Paving Grades as per the specifications.
Viscosity Grade bitumen is designed to take care of lowest temperature(responsible for cracking) and maximum temperature(responsible for rutting).
Onestop Supplies the following Paving grade bitumen:
- Penetration Grade:
60/70,80/100 & 30/40 - Viscosity Grade: VG-30, VG-40 & VG-10(IS 73-2013)
Benefits / Advantages of VG Bitumen over Penetration grade:
- VG system is based on fundamental engineering parameter(not empirical)
- Viscosity is measured at 60degree C and 135degree C, which takes care of both low and high-temperature susceptibility of the binder, which is not possible with penetration value at 25degreeC. Hence pavement engineers, contractors/consultants can have a better understanding of the binder's performance in the field.
- Any two same viscosity grade bitumens would give similar rutting performance in the field.
- Greater ease of handling to customers as Viscosity Value at two different temperatures(60degreeC and 135degree C) is available, which would enable users to measure accurate mixing and compaction temperatures.
- Minimum specified Kinematic Viscosity value at 135degree C helps to minimize the potential of tender mixes during construction.
- Viscosity graded bitumens are suitable for a wide range of temperature: 25degreeC for raveling/fatigue cracking. 60degreeC for rutting and 135degreeC for construction(mixing and compaction).
- IS 73-2006 has only 7 tests to evaluate a sample compared to 14 tests in penetration grade system. This reduces time and cost of testing without sacrificing its quality.
ONESTOP BITUMEN EMULSION FOR ROAD CONSTRUCTION
Today the main use of bitumen is in the road making industry for construction and maintenance. bitumen emulsions are a dispersion of bitumen in an aqueous continuous phase, stabilized by the addition of an emulsifier. They are prepared as emulsions at high temperatures but applied as solid dispersions at ambient temperatures. In road making, bitumen products are typically applied with mineral aggregate. The strong adhesion that occurs between the bitumen and mineral aggregate enables the bitumen to act as a binder, with the mineral aggregate providing mechanical strength for the road.
Bitumen is difficult to work with, at ambient temperatures, since it is a highly viscous material under these conditions. it can, however, be transformed into a workable state by blending with petroleum solvents or by emulsification with a surfactant in water to form a bitumen emulsion. Emulsified bitumen acts as a key tool in road maintenance and construction technology as it combines amazing versatility while offering multiple comparative advantages.
Light diesel Oil (LDO)
Light diesel oil is a blend of components from the distillation process of crude. It is used in engines with an rpm less than 750, such as boilers and furnaces. LDO is also referred to as distillate fuel or marked oil.
Light diesel oil is used as fuels in many applications :
- Boilers
- Furnaces
- Air pre-heaters
- Lower RPM engines
- Lift irrigation pump sets
- Fertilizer plants
- Bunker
- DG set
