Abstract
A member, screed and method for realigning material and compacting. A material realigning member is provided including structure for moving at least a first portion of a depth of a quantity of material laterally from an initial position thereof and then at least a second portion of the depth of the quantity of material back towards the initial position. In this fashion, aggregate particles may be moved in three horizontal directions, e.g., a direction of travel by a roller waveform, and both lateral directions by the invention, to realign material and allow for improved compaction.
Claims24
A screed for compacting a depth of material, the screed comprising:
- a vertically compacting surface having a first end and a second end;
- and
- means, extending from the vertically compacting surface between the first end and the second end, for moving at least a first portion of the depth of a quantity of material laterally from an initial position thereof and then at least a second portion of the depth of the quantity of material back towards the initial position.
A material realigning member for use on a material compacting screed having a first end and a second end, the material realigning member comprising:
- a plurality of elements, each having a curvilinear shape and extending substantially vertically from a surface of the material compacting screed for moving at least a first portion of a depth of a quantity of material laterally from an initial position thereof and then at least a second portion of the depth of the quantity of material back towards the initial position;
- and
- means for coupling the plurality of elements at a location between the first end and the second end.
A method of compacting paving material using a screed having a first end and a second end, the method comprising the steps of:
- compacting the paving material in a substantially vertical direction;
- and
- simultaneously moving at least a first portion of a depth of a quantity of the paving material under the screed laterally from an initial position thereof and then at least a second portion of the depth of the quantity of the paving material back towards the initial position.
A method of increasing compaction capability of a screed, the method comprising the steps of:
- providing a screed having a vertically compacting surface having a first end and a second end;
- and
- coupling a material realigning member to the screed at a location on the vertically compacting surface between the first end and the second end for moving at least a first portion of a depth of a quantity of the paving material laterally from an initial position thereof and at least a second portion of the depth of the quantity of the paving material back towards the initial position.
