Equipment Used for Bituminous Pavement Construction

Hi,
The main list of the equipment that we need for the construction of the bitumen pavements are:

  1. Boiler
  2. Sprayer/Distributor 
  3. Hot Mix Plants
  4. Cold Mix Plants
  5. Truck/Dumper
  6. Mechanical Pavers/ Finishers
  7. Rollers
  • Boilers: Boilers are used to soften the bitumen by heating it to certain temperature for its easy application.
  • Sprayer/Distributor: Sprayers are required for spreading/distributing the bitumen on the pavement.  If the bitumen is applied with pressure, they are known as pressure distributors.
  • Hot Mix Plants: Hot mix plants are required for mixing the aggregates, bitumen and any other required material to prepare the hot mix of the asphalt concrete. Aggregates are bitumen are needed to be heated up to a temperature of 150 to 200 degrees Celsius. 
  • Cold Mix Plants: Cold mix plants are required for mixing up the emulsion and the aggregates and so the main difference between the hot mix plants and cold mix plants is that we don't have to heat up the aggregates before mixing. Cold mixes are preferred in the cold regions because emulsions are applicable at low temperatures also.
  • Truck/Dumper: They are used to haul the mix to the place of its application and dump it on the paver or finisher.
  • Mechanical Pavers/Finishers: Mechanical paver are used to apply the asphalt concrete on the pavement and to partially smooth or compact it. 
  • Rollers: Rollers are effectively used to compact the bituminous concrete. For this purpose we use either smooth wheeled rollers or pneumatic rollers.
Thanks for you kind visit!
