Paving machines, also known as asphalt pavers, are heavy construction equipment used to lay asphalt on roads, parking lots, and other surfaces. They work by distributing and leveling hot asphalt material, ensuring a smooth and even finish. These machines typically have a hopper to hold the asphalt, a conveyor system to move it forward, and a screed to spread and compact the material. There are different types of paving machines, including tracked pavers and wheeled pavers, each designed for specific applications and terrains. Operators control the machine's speed and material flow, allowing for precise adjustments during the paving process.
