Road Paver Machine is a type of construction equipment used for laying asphalt concrete or concrete on roads, bridges, parking lots, and other places. It consists of various systems that work together to complete the paving task, mainly including the walking system, hydraulic system, and material distribution system.
The Road Paver Machine evenly spreads asphalt mixture on the road base and performs initial compaction and leveling. It comes in two types: tracked and wheeled. It consists of two parts: traction, paving, and compaction, leveling. The former includes the frame, power unit, walking device, hopper, material gate, scraper conveyor, spiral paver, and cab. The latter includes the traction arm, compaction mechanism, and leveling device.
To provide a smooth surface, the Paver Machine should move at a constant speed and maintain a consistent material buildup in front of the paver. An increase in material buildup or an increase in the speed of the paver will cause the Paver Machine to rise, resulting in more asphalt being laid down, forming a thicker asphalt layer and an uneven final surface. Conversely, a decrease in material or a decrease in speed will cause the paver to lower, resulting in a thinner asphalt layer.
The Road Paver Machine should provide a smooth and even surface behind the paver. To achieve a smooth surface, a free-floating Paver Machine is used. It is towed at the end of a long arm, which reduces the impact of the underlying terrain on the final surface. The height of the road paver is controlled by several factors, including the paver's attack angle, the weight and vibration of the paver, the material height, and the towing force.
