AI Technical Summary

Technical Problem

Existing paving technologies struggle to achieve homogeneous distribution and compaction of paving materials, leading to uneven and less durable paved surfaces.

Method used

A screed plate with a lower textured surface featuring a gradation pattern of protruding polyhedron elements and channeling grooves that progressively increase in number and decrease in size from the leading edge to the trailing edge, enhancing mixing and compaction of paving materials.

Benefits of technology

The solution results in a more homogeneous and consistent paving mat with improved durability and smoothness by effectively embedding aggregates and fines, reducing the visibility of windrows, and ensuring a denser, smoother finish.

Abstract

A screed plate for a screed assembly to be towed by a mobile paver has a lower textured surface including a plurality of protruding elements arranged in a gradation pattern. The gradation pattern is characterized by an increasing number or density of protruding elements between a forward leading edge and a rearward trailing edge of the screed plate. The gradation pattern is also characterized by a decreasing size of the protruding elements between the forward leading edge and the rearward trailing edge. The protruding elements may be shaped as oblong rhombic pyramids defining channeling grooves there between.
