Toll road infrastructure plays an important role in supporting the mobility and economy of the country and the surrounding regions. Stretches long with sturdy construction, Toll construction itself has a complex process. That is why heavy equipment is needed for toll road construction.
The construction of this toll road involves a series of stages, starting from land clearing, until finishing. Every process requires extra work and takes a short time. Therefore, toll road infrastructure development requires various types of heavy equipment, like excavator, bulldozer, wheel loader, and others.
The use of heavy equipment plays a role in ensuring work is efficient and quality or ideal end result. Through this article, Let's recognize what heavy equipment is operated for the construction of toll roads and their respective functions. Here are some heavy equipment for the construction of toll roads
1. Bulldozer
Bulldozer is a heavy equipment made to push, flatten, and explore various materials such as land, pasir, batu, and debris. This tool is equipped with a large metal blade (blade) in the front that can be raised, decreased, or tilted according to work needs.
In the construction of the toll road, bulldozer play a role in preparation of land to be ready to be utilized. This tool is operated to level the ground surface efficiently, move materials, and helps strengthen the soil structure by compacting it.
2. Excavator
Excavator is a heavy equipment that is commonly used in construction to dig soil and stones, Then load it into the truck. Equipped with bucket dan boom, This tool is able to carry out various tasks, like digging, material transfer, as well as the cleaning of the land.
In the process of building a toll road, excavator serves to clean the land from vegetation, rock, and debris before construction begins. This heavy equipment is also used in digging the soil for the manufacture of road foundations or drainage channels, and move the material to the area to be hardened.
3. Motor Grader
Motor grader is a heavy equipment that serves to level the asphalt surface evenly and stable. This tool works using a large knife (blade) which moves forward and backward repeatedly until it reaches the desired surface.
In the construction of the toll road, motor grader used in leveling the ground before asphalting. Besides that, This tool is also operated to form a slope according to road planning, and distributing materials such as soil and gravel in the construction area.
4. Dump Truck
Dump truck is a type of heavy vehicle specifically designed to transport large amounts of materials, like land, gravel, batu, or other material. This large vehicle has a cargo that can be lifted using a hydraulic system.
With the ability like this hydraulic, dump truck can pour materials that are easily transported to the destination location. Function dump truck in the construction of the toll road, namely to transport materials so that the work becomes faster.
5. Vibro Roller & Tandem Roller
Vibro roller is a heavy tool used to compact the soil, gravel, or asphalt in a road construction project. This tool works by combining static loads and vibrations to increase material density, until the road surface becomes stronger and stable.
In toll road construction, vibro roller serves to strengthen the foundation before the asphalt or concrete layer, reduce the air cavity in the material, and prevent land decline. Besides the heavy equipment, tandem roller It is also necessary to compose and flatten the soil efficiently.
This tool is equipped with two large drums that rotate and move back and forth above the ground surface to put pressure on the asphalt. Tandem roller play a role in compacting the asphalt so that the road surface becomes smoother, rata, and has strong endurance.
6. Asphalt Paver
Asphalt paver is a heavy tool that plays a role in determining the quality of the toll road based on the thickness and size of the aspal layer. This tool is equipped with hopper As a container for storage asphalt mixture before spreading it on the road surface.
Heavy equipment asphalt paver always used in toll road construction because of its ability. Asphalt power serves to distribute the asphalt mixture evenly and ensure the thickness of the asphalt layer according to planning.
7. Concrete Paver
Concrete paver is a heavy tool used to spread, compact, and leveling concrete in road construction. This tool serves to spread concrete evenly according to the specified thickness, make sure the concrete is solid without air cavity, and form the road surface so that it is flat.
8. Wheel Loader
Wheel loader have similarities with bulldozer, But this tool is faster and more efficient when operating on a flat surface. Different from bulldozer, wheel loader more focused on transporting and moving material.
This heavy equipment works using a bucket that touches the surface of the ground or material, then clapping it to enter bucket. After the material is fully transported, Then it will be moved to the destination location.
In toll road construction, wheel loader serves to transport and move the material from one point to another. Besides that, This tool can also help clean the area and level the soil before the asphalting process.
The process of using heavy equipment in the construction of toll roads
The use of heavy equipment for toll road construction is tailored to the work needs. With special components that are owned by each, Each type of heavy equipment has a different function.
So each heavy equipment will be used in different stages according to its function to facilitate work. The following is the process of using heavy equipment in the construction of toll roads:
Land preparation phase:
Preparation phase in the construction of toll roads includes land cleaning, Land leveling, and material transportation. Bulldozer Used to clean the area of vegetation and leveling the ground.
Excavator play a role in digging the soil for the foundation and moving unnecessary materials. Meanwhile, dump truck used to transport and remove the material to a specified location. This process is very important to ensure the land is ready for the next construction process.
Land leveling stage:
Leveling of land in the process of making a toll road aims to create a flat surface, stable, and ready for the next layer. This stage begins after the initial subgrade compaction process is carried out.
Motor grader used to level and form the ground surface according to the desired elevation. Component blade (knife) The length of this tool will be set the slope to smooth the surface and form the optimal drainage slope.
After the leveling is complete, vibro roller used to compact the soil to be more dense and stable. With the use of these two tools, the ground becomes stronger, rata, and ready for the next construction stage.
The level of compaction of the soil & asphalt layer:
Soil compaction stages & The asphalt layer in the manufacture of toll roads aims to increase the density and strength of the ground surface. The purpose of this compaction is so that the asphalt layer is able to withstand traffic loads in the long run.
At the level of compaction of the soil, vibro roller used to compose subgrade with a combination of vibration and heavy pressure. The process works to reduce the air cavity and increase soil stability before the further leveling process.
Once the aspal layer is stabbed, tandem roller used to compose asphalt with even pressure, make sure the surface is more flat, and free from air pores. The combination of these two tools ensures that the toll road has a sturdy structure, stable, and durable.
Asphalting or casting stage:
The stage of asphalting or casting in the process of making a toll road aims to form a strong road surface layer, rata, and durable. If the toll road uses asphalt, for asphalt paver Used to spread hot aspal mixtures evenly on compacted surfaces.
If the toll road uses concrete, for concrete paver used to spread, compact, and leveling the concrete mixture. This tool works by spreading concrete according to the desired thickness, ensure a flat surface, and form a texture pattern to increase the grip of the vehicle.
Level finishing and inspection:
Level finishing and inspection in the process of making a toll road aims to ensure the road surface is ready to be used with optimal quality. At a level finishing, roller an additional tandem roller or pneumatic tire roller very needed.
Both of these tools are used to provide final compaction so that the road surface is more flat, congested, and free from waves or small cracks. After that, Inspection is carried out using a road quality checking tool.
The road check is done with FWD (Falling Weight Deflectometer) to measure the carrying capacity of the road, Profileometer to evaluate the level of inflammation, as well as the thickness test equipment and material strength to ensure the road meets the standard specifications.
