A road roller is a heavy construction vehicle used to compact soil, gravel, or asphalt during road building and maintenance. It typically has large, heavy drums that roll over the surface, applying pressure to create a smooth and stable foundation. Road rollers come in various types, including static rollers, vibratory rollers, and tandem rollers, each designed for specific tasks. These machines are essential in the construction industry, ensuring that roads are durable and can withstand traffic loads. By compacting materials effectively, road rollers help prevent future issues like cracking and settling, contributing to safer and longer-lasting roadways.
