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 each with a leading element front and a trailing element stern. To improve the durability of the screed plate, the leading element fronts of the protruding elements can have a greater surface area than the trailing element sterns. For example, the protruding element can be polyhedrons and the leading element fronts can have extended or longer leading edges compared with the trailing edges associated with the trailing element stern. The increased surface area and material associated with the leading element fronts improves the wear characteristics of the protruding elements during paving operations.
Claims20
A screed plate for a screed assembly towed by a mobile paver comprising:
- a forward leading edge;
- a rearward trailing edge parallel to the forward leading edge;
- an upper attachment surface extending between the forward leading edge and the rearward trailing edge;
- a lower textured surface opposite the upper attachment surface, the lower textured surface having a plurality of protruding elements each including a leading element front oriented toward the forward leading edge and a rearward trailing stern oriented toward the rearward trailing edge, the leading element front having a first surface area greater than a second surface area of the trailing element stern.
A screed plate for a screed assembly towed by a mobile paver comprising:
- a forward leading edge;
- a rearward trailing edge parallel to the forward leading edge;
- an upper attachment surface extending between the forward leading edge and the rearward trailing edge;
- a lower textured surface opposite the upper attachment surface, the lower textured surface having a plurality of protruding polyhedron elements each including an element base and an element apex, the plurality of protruding polyhedron elements further each including a leading edge and a trailing edges each extending between the element base and the element apex, wherein the leading edge is longer than the trailing edge.
