Asphalt Paver
View system integration details
This page explains how Screed is classified within Machinery and Equipment Manufacturing. Technical values and manufacturer relationships are research references; confirm the current specification and supplier evidence for each order.
A critical component of an asphalt paver that levels, compacts, and finishes the asphalt mat to specified thickness and smoothness.

A practical evidence checklist for RFQ preparation and supplier evaluation.
CNFX does not score or rank suppliers. Buyers must verify all claims and documents with the legal manufacturer before ordering.
The screed is the rear assembly that receives asphalt mix from the augers, spreads it evenly, and provides initial compaction and surface finishing. It determines the final thickness, density, and smoothness of the pavement layer.
Thickness is controlled by adjusting the screed's attack angle relative to the tow point. The screed floats on the mix, and the angle determines the amount of material passing underneath.
The working width ranges from 2.5 to 9.0 meters, including hydraulic extensions. The maximum paving thickness is 300 mm, depending on material and compaction requirements.
The listed parameters are reference ranges. Actual values depend on the specific model, configuration, and application. Always confirm with the legal manufacturer or supplier to ensure suitability.
