A road roller or compaction roller is one of the most crucial equipments in road construction. Its primary function is to prepare the foundation of construction projects. However, due to the wide range of options available, it can get overwhelming to make a choice. You have to consider both the kind of project you are required to work on and the features of the equipment. In this guide, we will help you decide based on these factors.
How to choose the right road roller based on the task?
Depending on the task, choose the right roller with the specifications and features to support the task. Here are the factors you need to keep in mind:
1.Type of job
For surface compaction tasks, different rollers are suited for various types of compaction. For uniform compaction tasks, where the surface’s density and viscosity have to be maintained, a cylindrical road roller, or a single drum is a good option. They are best for sidewalks, driveways, and building foundations without angled surfaces. Double drum rollers are better suited for projects requiring a thorough and deeper compaction.
2.Size of the job
Lengthy construction projects with large space requirements will benefit from a double-drum road roller. Double drum rollers are especially suitable for highways since they are lengthy, spacious, and require less traction. For smaller compaction and leveling projects, like village roads, driveways, and sidewalks, single drum rollers are more suitable. They are easily maneuverable even on narrow and inclined roads. For even narrower and tighter spaces, a pad foot roller or a sheep foot roller can also do the job.
3.Type of surface
The type of surface you will be working on is equally important in determining the right road roller for the job. For asphalt and bitumen surfaces, smooth drum rollers are a good option. Drum rollers, whether double or single, work great with granular soil surfaces. A pad foot roller is perfect when the soil has cohesive elements like clay, silt, loam, etc.
Now that you have understood how to choose a suitable road roller, depending on the type of project, we will guide you on selecting the perfect road roller based on its features.
How to choose the right road roller based on its specifications?
Selecting the perfect road roller also depends on its features and its specifications. Here are the factors you need to keep in mind:
1.The type of engine
Always check whether the road roller you are purchasing has an air-cooled engine or a water-cooled engine. Air-cooled engines require routine maintenance if the project is in a dusty, hot environment. If you are planning to purchase a used road wheel with an air-cooled engine, check for any excessive oil consumption from the oil pressure gauge because it can indicate problems in the system. If you purchase a water-cooled engine-based road roller, look out for cracks and fluid leaks.
2.Engine output and emissions
Double drum rollers have better engine power and output and are better suited for moving heavier objects. Also, consider the emission standard of the road roller you are purchasing. Rules and regulations in countries are getting stricter about emission levels. So go for road rollers with comparatively lower emissions that preferably combine diesel and HVO fuel to reduce the emission of greenhouse gasses.
3.Compaction effectiveness
Road rollers operate in two vibration modes. Abundance refers to the upward development of the drum, from which you can figure out its power and recurrence. Recurrence means the frequency at which the shaft pivots within the drum. For projects involving softer soil and sand, higher recurrence is better, while lower recurrence is better suited for firmer soil.
4.Size of the drum roller
The “7-ton drum class 67” with a road roller is perfect for construction projects that involve parking lots, building establishments, banks, etc. More demanding projects like highways, reservoirs, and large commercial sites like airports, shopping complexes, etc. require larger road rollers with 84” wide drums.
Choosing the perfect road roller for a project is crucial to achieving the best productivity and results. With the help of this guide, you will be easily able to figure it out.
