Roads
once constructed needs constant repair as it is prone to wear and tear
due to weather influence and rolling traffics. A chip spreader through
chip sealing gives special protective wearing surface to an existing
pavement. A chip spreader is a unique self-propelled machine for laying
of precoated chipping surface treatments provides long-time conservation
and maintenance of the roads. Thus for maintaining the quality and
giving it a lasting effect, stone chipping is one of the most effective
method which is done by chip spreader.Mechanical Operations
Chip spreader is powered by diesel engine and has spread hopper of different size. An individual one foot power gates gives the variable hopper flexibility and increases productivity. Other equipments used by chip spreader are conveyor belts, container, hydrostatic drive, planetary axle etc.
Before spreading chips, asphalt is mixed with water. This emulsified mixture is then applied to the road using a chip spreader or spray truck. As soon as the liquid asphalt meets the road surface, the water starts to evaporate. After this a layer of crushed gravel is applied by a spreader. Next, the gravel is compacted and embedded into the asphalt by rubber-tire rollers.
Applications
Chip spreader is one of the important machine for the maintenance of an infrastructure. Its other applications are :
- Chip spreader distributes different quantities of chips for optimum grip of asphalt layers evenly.
- Chip can be distributed directly behind the pavers.
- It can also be applied to bituminous chips also.
- Chip flows continuously without the problems of oversized grains and humidity.
