When it comes to paver screeds, users in the paver industry must be familiar with it. But if you are allowed to say what it does, I believe you will only be able to tell the truth. In fact, the screed is a main working device of the paver.
The main function of the screed is to level, shape and pre-compact the asphalt pavement, stabilized soil and other mixed paving materials conveyed by the spiral distributor, and provide good working conditions for the subsequent compaction of the roller.
In addition, the screed can be widened to different paving widths within a certain range to achieve continuous paving operations of different breadths and effectively guarantee the lateral slope of the road surface section in the same breadth. With the continuous development of science and technology and the construction of highway network and railway network, higher requirements are placed on the smoothness and compactness of road surface and roadbed. Since the screed is in direct contact with the mixture, the behavior of the screed will be directly reflected on the road surface after paving, so the screed and its related spiral material distributor is one of the key devices to ensure the quality of the paving.
