Asphalt leveling is an important process in road construction to ensure a smooth and durable surface. This job requires special techniques and processes that are not short. Therefore a heavy equipment is needed to level asphalt so that the work can be efficient and the results are quality.
There are various types of heavy equipment that can be used to level asphalt, starting from vibratory roller, asphalt paver, etc. This heavy equipment is specifically designed to handle asphalt leveling work easily, fast, and measured compared to manual power.
Besides relying on heavy equipment, It should also be noted that the quality of asphalt leveling is also influenced by several other factors. Through this article, Let's recognize what heavy equipment to level asphalt, factors that affect the quality of leveling, and tips for using heavy equipment effectively.
Here are some heavy equipment for leveling asphalt and their respective functions:
1. Vibratory Roller
Vibratory roller is a heavy equipment used to compact and flatten the asphalt layer with the help of vibrations. This tool has drum vibrating that works with a combination of static and dynamic pressure, so that it can increase asphalt density to the maximum.
Vibratory roller equipped with a hydraulic system to control the speed and pressure of the drum, as well as vibration mechanisms that help compress the material efficiently.
In the process of leveling asphalt, This tool is carried on a newly circulated surface. Then the vibration is activated to increase asphalt density. Roller moved back and forth repeatedly until the road surface reaches the optimal density before vibration is turned off for the finishing stage.

2. Asphalt Paver
The other type of heavy equipment needed to level asphalt is asphalt paver. Asphalt paver It is a tool that works to spread hot aspal mixtures evenly on the road surface before the compaction process.
This heavy equipment consists of several main components, starting from hopper as a forum for holding asphalt, conveyor which transports asphalt to auger, as well as screed which functions to level and give initial thickness to the asphalt layer.
In the work process, hot asphalt poured into hopper in advance. Then conveyor bring the mixture to auger in charge of distributing asphalt evenly. Screed will level up and slightly compact the asphalt before finally entering the stages of further compaction with the roller.
3. Tandem Roller
Tandem roller is a compactor that has two drums, namely on the front and back. Both components of the drum are used to level and compact asphalt.
Roller It works with static pressure given by the weight of the device and can be equipped with a vibration system to increase the effectiveness of compaction. Drum on tandem roller Able to put even a subtraction so that it can eliminate the air cavity in the asphalt mixture.
This tool also has a water tank that serves to prevent asphalt from sticking to the drum. In the process of leveling asphalt, tandem roller run back and forth on the surface of the road until the desired density is achieved.
4. Pneumatic Tire Roller
Pneumatic tire roller is a compactor that uses a high pressure rubber wheel to press and level the asphalt layer. This tool has an advantage in putting more flexible pressure than roller with steel drums. This tool is able to increase density and flexibility of the road surface.
Pneumatic tire roller consists of several rubber wheels filled with air and can be given additional ballast to adjust the compaction pressure. Besides that, This tool is also equipped with a water tank to prevent asphalt from sticking to the tire.
For the asphalt leveling process, This tool is operated by walking back and forth above the asphalt layer. This way of working will put evenly stress throughout the surface until the asphalt reaches optimal density.
5. Motor Grader
Motor grader is a heavy equipment used to level the surface of the ground or basic material before asphalting is carried out. This tool is equipped moldboard or a large knife that can be adjusted angle and height.
Component moldboard can be adjusted to ensure the slope and thickness of the surface according to road construction standards. Motor grader also has a hydraulic system that helps control position blade so that the leveling process is more precise.
In its use, This tool is run to level the surface of the ground or basic aggregate. Component blade lowered and arranged angle so that it can produce a flat surface and ready for the next asphalting process.
Factors that influence the quality of asphalt leveling
There are several factors that can affect the quality of the results of asphalt leveling. In addition to the right use of heavy equipment, The following are the things that also affect the quality of asphalt leveling:
- Selection of heavy equipment in accordance with the project conditions: The use of heavy equipment must be adjusted to the type and thickness of the asphalt layer so that the maximum compaction.
- Correct operating techniques: The method used by heavy equipment operators must match the standard, including the speed of the tools and leveling patterns used.
- Maintenance of heavy equipment to keep functioning optimally: Heavy equipment that gets maintenance routinely and precisely will work optimally in leveling asphalt.
- Operator's experience and skills: Heavy equipment operators must have good skills and experience to ensure optimal leveling results.
- Quality of Field Control and Supervision: Supervision during the asphalt leveling process is very important to ensure that all of the above factors are running according to the established quality standards.
- Type and quality of asphalt material: The composition of the right asphalt mixture is very influential on the durability and strength of the resulting road.
- Asphalt temperature during an overlap: Aspal should be spread at optimal temperatures to be easily flattened and compacted. If it's too cold, asphalt will be difficult to blend well.
- Base surface conditions (subgrade dan base course): Uneven or uneven base surface can cause asphalt deformation or decrease in durability.
- Weather conditions: Air temperature, humidity, and rainfall affects the hardening time of asphalt and the end result. Overlapping should be done in supportive weather conditions.
Tips for using heavy equipment for effectively leveling asphalt
The use of heavy equipment in the right way can make the asphalt leveling run effectively. Here are some tips for using heavy equipment so that asphalt leveling can be optimal:
- Selection of the right tool: The use of heavy equipment must be adjusted to the type and thickness of the asphalt to be leveled. For example asphalt paver used to spread aspal with uniform thickness.
- The ideal asphalt temperature regulation during the compaction process: Asphalt must remain at the optimal temperature (around 125-145 ° C.) When conducted compaction so that the material can be integrated.
- Technique overlapping so that the results are evenly distributed: Overlapping Or overlapping the path during compaction is very important to avoid gaps or uneven parts.
- Routine maintenance: Heavy equipment used for leveling asphalt must always be in prime condition in order to work optimally. Routine maintenance is very important to prevent damage and maintain heavy equipment performance.
- Role of experienced operator in handling heavy tools: Experienced operators have skills in controlling heavy equipment with precision, Including regulating speed, direction, as well as appropriate compaction techniques.
