Abstract
An apparatus for spreading, screeding and/or compacting cold paving material to a surface to be paved including a frame of a width substantially equal to the width of the surfaced to be paved. The frame has first and second sides that define the width of the frame. The apparatus includes a pile breaker that has one or more pile breaking rollers that are shorter than the full width of the frame and are connected to the frame. Behind the pile breaker, there is a height-adjustable screed roller for screeding the paving material. There may also be a compacting roller behind the screeding roller to compact the paving material. The cold paving material can be cold asphaltic mixture or similar material, Portland cement concrete or similar material or other paving material at ambient temperature.
Claims22
An apparatus for spreading and screeding cold paving material to a surface to be paved, comprising:
- a frame having first and second sides defining a width to be paved;
- a pile breaking assembly having at least one pile breaking roller,
- wherein the pile breaking roller has a width, and wherein the width of the pile breaking roller is smaller than the width to be paved;
- and
- a height-adjustable screed roller for screeding the cold paving material,
- wherein the screed roller is connected to the frame and positioned behind the pile breaker.
An apparatus for spreading, screeding and compacting cold paving material to a surface to be paved, comprising:
- a frame having first and second sides defining a width to be paved;
- a pile breaking assembly having at least one pile breaking roller,
- wherein the pile breaking roller has a width, and wherein the width of the pile breaking roller is shorter than the width to be paved;
- a height-adjustable screed roller for screeding the paving material,
- wherein the screed roller is connected to the frame and positioned behind the pile breaker in the direction of movement;
- and
- a compacting roller behind the screed roller.
A screed roller assembly for use in an apparatus for spreading and screeding cold paving material to a surface to be paved, the screed roller assembly, comprising:
- a screed roller coupled to the apparatus for screeding and partially compacting cold paving material;
- and
- a plurality of gauge wheels removably coupled to the screed roller for adjusting the height of the screed roller within the apparatus.
An apparatus for spreading and screeding cold asphaltic mixture to a surface to be paved, comprising:
- a frame having first and second sides defining a width to be paved;
- a pile breaking assembly having at least one pile breaking roller,
- wherein the pile breaking roller has a width, and wherein the width of the pile breaking roller is shorter than the width to be paved;
- and
- a height-adjustable screed roller for screeding the paving material,
- wherein the screed roller is coupled to the frame and positioned behind the pile breaker in the direction of movement.
An apparatus for spreading, screeding and compacting cold asphaltic mixture to a surface to be paved, comprising:
- a frame having first and second sides defining a width to be paved;
- a pile breaking assembly coupled to the frame having at least one pile breaking roller, wherein the pile breaking roller has a width, and
- wherein the width of the pile breaking roller is shorter than the width to be paved;
- a height-adjustable screed roller for screeding the paving material,
- wherein the screed roller is connected to the frame and positioned behind the pile breaker in the direction of movement;
- and
- a compacting roller coupled to the frame and positioned behind the screed roller.
A method for applying cold paving material to a surface, comprising:
- mixing the cold paving material;
- dumping the cold paving material in front of a cold paving apparatus;
- flattening the cold paving material using the cold paving apparatus;
- spreading the cold paving material using the cold paving apparatus;
- and
- compacting the cold paving apparatus using a compacting device.
