What are the two primary components of a paver?

The two primary components of a paver are the tractor and the screed. The tractor is the main chassis that propels the paver forward and provides the necessary power to operate various functions of the machine. It typically houses the engine and is responsible for the mobility aspect of paving operations.

The screed is mounted on the rear of the tractor and plays a critical role in shaping and finishing the asphalt mat. It spreads, levels, and compacts the asphalt to the specified thickness and width, ensuring a smooth and even surface. The interaction between the tractor and the screed is vital for achieving the desired roadway quality, making these two components essential to the overall function of the paver.

While other components mentioned, such as leveling arms or flow gates, are also integral to the asphalt paving process, they do not serve as the primary structural elements that define the operation of a paver. The tractor and screed work in tandem to execute the fundamental task of laying down hot mix asphalt efficiently and effectively.
