Road oil bitumen
Swiss Oil Ukraine sells viscous road oil bitumen of the BND 60/90 and BN 70/100 grades, as well as a bitumen emulsion.
Road oil bitumen is a product that is obtained by oxidizing residues of atmospheric vacuum distillation of oil and selective separation of oil products (deasphalting asphalts, selective refining extracts), as well as compounding highly viscous oxidized and non-oxidized products or direct distillation of oil (bitumen.
The most widely used material was in the field of construction and repair of pavement in all climatic regions of Ukraine.
Characteristics of bitumen:
- Ductility (extensibility) - an indicator of the plasticity of bitumen, which determines its ability to give a thread of a certain length when stretched (determined by the maximum long thread into which bitumen can stretch without breaking at 25 oC
- Penetration is a conditional quantity that characterizes the viscosity and hardness of bitumen. It is determined by the penetration depth of a special steel needle into the bitumen layer in 5 seconds with a force of 1H
- Thermostability - characterizes the softening temperature of the bitumen mass, flash and the transition of bitumen into a brittle state. In road construction, it is the thermal stability of bitumen that is its most important indicator, since it directly affects the durability of asphalt concrete pavement made of bitumen-containing asphalt mixtures
- Filtration Limit
