2042538 AB500-2 Screed Plate for Asphalt Paver Spare Parts

Product Introduction:

The screed plate kit, the core component of a paver’s screed system, works in a sequential process: it first receives loose materials (e.g., asphalt mixture) from the paver’s feeding system, then its front vibration mechanism compacts the materials initially via high-frequency vibration to fill gaps; after that, its built-in vibration mechanism further compacts the materials horizontally to reduce air bubbles. Meanwhile, its heating system (usually electric or gas-powered) keeps the surface at a proper temperature to prevent sticky materials from adhering. Finally, as the paver moves forward steadily, its smooth bottom scrapes the materials into a road layer meeting design requirements for thickness and flatness, with some models also having telescopic parts to adjust width or automatic leveling devices to handle uneven roadbeds.

What are the functions of different sizes of screed plates for pavers?

In terms of size, screed plate kits of different sizes meet different paving width requirements: Narrow-width screed plate kits  are suitable for construction in narrow areas such as narrow alleys, community roads or beside pipelines, and can fit limited spaces flexibly. Regular-width screed plate kits are applied to roads of regular width like urban main roads and township highways, balancing work efficiency and operational convenience. Wide-width screed plate kits are designed for wide-road construction such as expressways and large squares—they can reduce the number of joints and improve the overall flatness of the road surface. There are also telescopic screed plate kits, which can adjust the width to adapt to changing paving width needs. They eliminate the need for frequent replacement of screed plate kits, saving time and costs.

What are the functions of different materials for paving machine screeds?

In terms of material, different materials determine the core performance of screed plate kits: Screed plate kits made of ordinary low-carbon steel have low cost and moderate hardness. They are suitable for paving non-adhesive base materials like stabilized soil and gravel, and can meet general strength requirements. Those made of high-strength wear-resistant steel (e.g., Hadox, NM450) have higher hardness and strong wear resistance—they are not easy to deform or wear when in long-term contact with rough materials or rolling stones, so they are suitable for high-frequency and high-load asphalt surface layer paving. Screed plate kits made of stainless steel have a smooth surface and are not easy to stick to high-temperature asphalt mixture, which can avoid roughness and scratches on the paved surface caused by residual materials, ensuring the smoothness of the asphalt road. Some screed plate kits made of composite materials (e.g., steel base with wear-resistant coating) combine high strength and anti-adhesion properties, balancing durability and paving effect—they are suitable for long-term operation under complex working conditions.
