What Is a Road Roller?
A road roller is a construction machine used for compacting the ground during construction projects.
Named for its use of a cylindrical roller attached to the vehicle body to compact roads, it is also known as an iron wheel roller or smooth roller. Official documents from government agencies may refer to it as a compaction machine.
Uses of Road Roller
Road rollers are utilized in various applications such as foundation construction and roadwork, including asphalt compaction and ground leveling.
By traversing with a heavy vehicle body, they compact the ground. Different types, including tandem and tire rollers, must be selected based on the location, environment, and requirements for compaction.
In recent years, construction cases employing Information and Communication Technology (ICT) have emerged. Real-time monitoring of compaction status and autonomous operation enhance quality and operational efficiency.
Principles of Road Roller
A road roller is one type of compaction machine. It compacts the soil by compressing the space within the soil through the machine’s weight and the wheel load of the roller. Tire rollers, aside from wheel load, achieve optimal compaction by adjusting tire air pressure to alter ground pressure according to soil type and work requirements.
Some compaction machines utilize vibration and impact, contributing to a smoother finish by choosing the appropriate machine for the application.
