is a crude petroleum product which is cheap, durable and hence the
popular material for carrying out various constructions. Asphalts are
produced and processed in a asphalt plant which is either stationary or
mobile. Mobile asphalt plants are generally truck or trailer mounted in
which asphalts are mixed in certain proportion for the purpose of
constructing various infrastructures.
The mobility gives new dimensions and versitality to asphalt mix plants and
higher degree of capacity utilization. Plants can also be erected on the
job site without concrete foundation or can be assembled on wheels.
The plant consists of blower, filler, dryer, bitumen pump, conveyor,
four bin feeder, bitumen tank, fuel tank etc. The filler units and
blowers are made from steel plates. For drying and mixing of the asphalt
there are two drums. For liquid asphalt there is a heated tank. After
being thoroughly dried and heated they are discharged directly into an
insulated holding or surge bin at the back of the mobile asphalt plant.
Through electric heating system liquid asphalt is heated. After the end
of the process, materials are ready for road construction.
There are certain advantages and applications of mobile asphalt mix plants :
- Mobile asphalt can relocate themselves on job site thereby
saving enough time and money.
- They are utilized for the construction of roads and pavements
- Runway of airport etc.
