Petroleum is the foundation of road. Used with combinations of different raw materials, petroleum gives smooth surface, strength and durability to modern roads. Tap to check the key players in road surfacing.
Also known as Asphalt, bitumen is the most important petroleum in road surfacing. Viscoelasticity, waterproofing, durability and adhesion are the key properties of bitumen making it essential for road projects.
This viscous, black and sticky material is available in different grades including bitumen VG10, VG30 and VG40.
This is asphalt cement mixed with petroleum solvents. Low viscosity of cutback asphalt makes application easier in lower temperatures. Further, the surface gets stronger once the solvent evaporates.
Common types of cutback asphalt used in road surfacing are RC (Rapid), MC (Medium) and SC (Slow).
It is a mixture of asphalt, water, and an emulsifying agent used for patch repairs and tack coats. Bitumen emulsion is ideal for cold mix and wet conditions.
Having high elasticity and capacity to withstand regular temperature shifts, PMB is used for highways, runways and heavy-load zones.
Also known as softening agent, flux oils are less viscous petroleum distillates. These are added to hard asphalt to reduce viscosity for specific applications or weather conditions.
