The function of the ironing plate:

The screed is a main working device of the paver. Its main function is to level, shape, and pre compact the asphalt concrete, stabilized soil, and other mixed paving materials transported by the spiral distributor, providing good working conditions for further compaction by subsequent rollers. At the same time, the ironing plate can be widened to different paving widths within a certain range, achieving continuous paving operations across different widths and effectively ensuring the transverse slope of the road surface section within the same width. With the continuous development of science and technology, as well as the construction of highway and railway networks, higher requirements are put forward for the flatness and density of road surfaces and subgrades. Due to the direct contact between the screed and the mixture, the properties of the screed will be directly reflected in the paved road surface. Therefore, the screed and its related spiral distribution device are one of the key devices to ensure the quality of paving. In recent years, advanced compaction technologies such as double vibration compaction, high-strength pulse vibration compaction, and eccentric vibration compaction have been adopted by Aoping, resulting in a pre compaction compactness of over 90% of the mixed material after paving. This effectively improves the smoothness and compactness of the paving, reduces the number of compaction cycles of the roller, and significantly improves production efficiency and work quality. With the continuous innovation and development of technology, the design of ironing plates will become more reasonable and complete, and trigger a new round of market competition.
