Asphalt Paver Screed Bottom Plate Assembly including Heating Rods Screed Plates and Tamper Bars
The screed bottom plate, along with the main screed plate assembly, makes up the screed plate assembly on an asphalt paver. The screed bottom plate attaches to the underside of the main screed plate and together they help level, smooth, and compact asphalt material as it leaves the paver. Attached to the bottom plate are key components, including heating rods, tamper bar, and pressure bar. The primary purpose of the screed bottom plate is to secure all the parts required for proper compaction and smoothing of asphalt material. The steel plate provides a solid, durable surface that can withstand exposure to high heat and vibrations. The heating rods are attached directly to the bottom of the steel plate to heat the screed plates to the desired paving temperature. The tamper bar is a steel bar that mounted to the very rear of the screed bottom plate. It works to further compact and smooth the asphalt material as it passes under the screed. The pressure bar with the hydraulic pulsing system generates high density compaction effects on the pavement under paving, and it has to withstand huge stresses during the process.
Crafts asphalt paver screed bottom plate assembly can be perfect fit to almost all the popular brand asphalt pavers, such as VOGELE, DYNAPAC, CAT etc. The components attached to the screed bottom plate work together to effectively spread, compact, and texture the asphalt material. The heated screed plates warm the asphalt to the proper temperature for working. The vibrators rapidly compact the material under the screed. Finally, the tamping bar provides the initial surface texture and compaction as the asphalt emerges from under the screed. By attaching multiple components required for paving to the screed bottom plate, the plate helps enable the screed assembly to carry out its function. The bottom plate, along with the main screed plate, makes up the heart of the screed system. Its components work together to achieve the essential paving requirements of longitudinal joint compaction, surface smoothness, pavement depth control, and surface texture as the asphalt material flows under the powerful screed plate assembly during the paving operation.
