The 2042538 screed plate serves as the bottom wear component in asphalt paver screed systems, contacting hot asphalt material directly during paving operations to produce the finished mat surface and provide initial compaction. Produced by JESTIN, a manufacturer with 14 years of experience in asphalt paver wear parts, this plate is designed for bolt-on installation on ABG and compatible extending screed units. The component supports paving operations for highway construction, airport runway paving, bridge deck overlay, and municipal road projects where consistent mat smoothness is required. This part serves asphalt paving contractors, equipment rental fleets, and heavy equipment repair facilities conducting commercial paving operations.
During paving, the screed plate floats on the asphalt material while the screed's vibration and tamper bar systems provide initial compaction. The precision-ground bottom surface determines the final mat texture and smoothness, directly affecting pavement smoothness readings and density levels. Worn screed plates cause mat imperfections including tears, waves, and inconsistent density that require additional roller compaction or may result in pavement smoothness penalties on specification projects.
This 2042538 screed plate fits ABG AB500-2, AB500-2TV, AB600-2, and ABG325 screed systems, plus cross-compatible applications on Vogele S1800-3/S2100-3 and Dynapac SD2500/SD2530 pavers equipped with matching extending screed units. Verify mounting hole positions and dimensions against your existing plate before ordering, as some screed configurations use different hole patterns.
Each screed plate is manufactured from 40Cr induction-hardened alloy steel, selected for its combination of wear resistance and stability under elevated temperatures encountered when working with hot asphalt (150-180°C). The material maintains hardness at operating temperatures without excessive softening or deformation during continuous paving operations. Material certifications are available for commercial orders upon request.
The bottom contact surface undergoes induction hardening to a depth of 4-6mm, achieving surface hardness of 52-56 HRC to resist abrasive wear from asphalt aggregate. The plate body maintains a core hardness of 28-32 HRC to resist impact and prevent cracking when encountering hard objects in the asphalt mix. The bottom surface is precision ground to a flatness tolerance of 0.02mm across the entire plate length and a surface roughness of Ra 1.6μm to produce consistent mat texture.
Production follows ISO 9001:2015 quality management system standards. Each plate undergoes flatness inspection after grinding, hardness testing at multiple points across the surface, and mounting hole position verification. Sample plates from each production run undergo wear simulation testing to verify consistent performance across batches.

Before installation, clean the screed mounting surface thoroughly to remove all asphalt residue, old gasket material, and rust. Inspect the screed frame for flatness; replace or machine the frame if warping exceeds 0.1mm across the mounting surface. Install mounting bolts with high-temperature thread lubricant and torque to 120 Nm in an alternating sequence from center to ends to prevent plate distortion. After heating the screed to operating temperature (110-130°C) and operating for 2 hours, re-torque all bolts to specification while the screed remains at operating temperature.
Inspect screed plates daily before beginning paving operations. Measure plate thickness at multiple points; replace plates when thickness wears below 12mm (original thickness 16mm) or when uneven wear exceeds 0.5mm across the plate width. For high-volume paving operations, replace plates after 15,000-25,000 tons of asphalt throughput, depending on aggregate abrasiveness. For best mat quality results, replace all plates on a screed section at the same time rather than replacing individual plates.
At the end of each paving day, clean the screed plate surface while still hot using a wire brush and release agent to prevent asphalt buildup. Apply release agent before starting each day's paving to prevent asphalt sticking. Check bolt torque weekly during continuous operation. Store spare plates in a dry environment to prevent corrosion on the ground surface.
This plate replaces OEM part number 2042538 and equivalent aftermarket parts with matching dimensions and hole patterns. For complete screed system rebuilding, this plate works with tamper bars 4812064058 and 54612726, wiper rubbers 4601112254 and 4601112253, screed heating elements, and wear strips.
For major screed rebuilds, order screed plates together with matching tamper bars, wiper rubbers, and mounting hardware as a complete kit. Replacing all wear components simultaneously restores screed performance to original specifications and reduces labor time compared to replacing parts individually.
Stock orders ship within 5-10 working days from the Shanghai warehouse. Bulk orders of 100 units or more qualify for volume pricing. Each plate is coated with anti-corrosion oil and individually wrapped, then packed in plywood crates suitable for international shipping. Express delivery options are available for emergency repair situations to minimize equipment downtime.
The 1-year warranty covers defects in material and workmanship, including premature cracking, uneven hardening, or delamination of the hardened layer under normal operating conditions. Warranty does not cover damage from improper installation, operation without sufficient heating, or damage from foreign objects in the asphalt mix.
For enterprise customers requiring non-standard dimensions or different material specifications, custom production is available with a minimum order quantity of 200 units. Technical drawings are provided for customer approval before production commences. Custom hardening specifications are available for specialized applications including polymer modified asphalt paving.
Service life typically ranges from 15,000-30,000 tons of paved asphalt, depending on aggregate type, paving temperature, and mat thickness. Paving with highly abrasive slag aggregate reduces service life compared to standard limestone aggregate.
While individual plates can be replaced, replacing all plates on a screed section at the same time provides more uniform mat quality and prevents height mismatches between old and new plates that cause mat imperfections.
The standard minimum order quantity is 20 units for stock parts. Sample orders of 1-2 units are available for fitment verification and field testing, with sample pricing applied.
Yes, all plates include pre-drilled mounting holes matching OEM specifications. No additional drilling or machining is required for standard installation on compatible screed models.
