Asphalt is also outlined as natural or mixture within which hydrocarbon is related to the inert mineral matter. It’s a solid or semi-solid sticky product, fashioned by partial evaporation or distillation of bound fossil fuel oils.
It is soluble in varying degrees in carbon di-sulphide. Asphalt is mostly used in construction works like in road pavement also in DPC works.
Properties of Asphalt
- It’s sticky or adhesive and binds powerfully as cement. It adheres perfectly to wood, stone, concrete, and metal.
- It’s sometimes solid or semi-solid in the state.
- It is black brownish in color.
- It is waterproof.
- Asphalt was durable and retains its properties for several years.
- Elastic in nature
- It becomes plastic and workable when heated.
- It possesses binding.
- Asphalt is not seriously affected by adverse weather.
- It is a good conductor of heat, sound, and electricity.
- It is ductile and can be stretched without breaking.
- Was soluble in varying degrees in carbon di-sulphide.
Use of Asphalt in constructions works
- It is used as a damp-proof course (DPC) or preventing dampness in walls, floors, and roofs of buildings.
- It is used as a water repellent layer over flat roofs, arches, and basements.
- It’s used for lining walls of tanks, swimming pools and in other such places.
- Used for smooth and non-absorbent flows of bathrooms, latrines, etc.
- It’s used for making ready paints and roofing felts.
- In the form of asphalt mortar and asphalt concrete, it is extensively used for paving roads in different ways such as dressing, grouted macadam, coated macadam, etc.
- It is used for flooring purposes.
- It is used for preparing useful electric insulating materials when mixed with wood tar pitch, rubber, resin, and other suitable compounds.
