Abstract
A paving machine and edger providing precompaction, horizontal shear compaction and primary compaction of a paving material. The edger includes a plurality of adjustment apparatus for vertical and angular adjustment. A plurality of height indicators are provided for measuring the vertical position of the compaction surfaces of the edger. A wedge extender is removably attached to the edger. The edger is capable of creating a stepped tapered ramp having a highly compacted step and a highly compacted upper portion of the tapered portion.
Claims26
A paving machine comprising:
- a system for providing precompaction of a paving material;
- a system for providing horizontal shear compaction of the paving material;
- and
- a system for providing primary compaction of the paving material.
1 more element
An edger comprising:
- a first compaction surface;
- a second compaction surface;
- a substantially vertical third compaction surface between the first compaction surface and the second compaction surface;
- wherein the vertical third compaction surface is set at an angle in a horizontal lateral direction relative to a forward direction of movement of the pavement edge maker to receive and compact material in a horizontal direction;
- a wedge extender removably attached to the second compaction surface;
- and
- a mounting assembly for mounting the edger on a screed.
