Definitions
- the present invention relates to a paver for laying asphalt mixture on an applied surface and more particularly, relates to a technique for improving the efficiency of conveyance of the paver and that of laying operation for paving materials performed by the paver.
- a method of laying a plurality of paving materials in layers has been employed for improving drainage and noise-reduction properties as well as for reducing a cost spent for the materials.
- a thin layer is laid to form an upper layer
- aggregate projecting from or coming out of the surface of the upper layer might be drawn by a screed to result in forming damages and scratches on the surface of the upper layer, and therefore in order to prevent such formation of damages, it is necessary to lay the upper layer on the lower layer in unhardened state at a high temperature.
- the temperature is quickly lowered so as to make it difficult to obtain an appropriate density of the layer after application of rolling to the layer.
- a paver capable of simultaneously completing pavement of multiple layers (it will be hereinafter referred to as a multi-layer paver) has been utilized.
- the attachment should desirably be conveyed without being dismounted from the base paver by taking into consideration the conveying efficiency of the base paver and the attachment.
- the overall height of the paver becomes large, and as a result, the top end of the asphalt paver might come into interference with a lower face of a structure such as a bridge during conveying of the paver. For this reason, even if the conveying efficiency of the asphalt paver might be decreased, it has been necessary for the base paver and the attachment to be individually conveyed.
- the asphalt paver be provided with a hopper having a large capacity thereof capable of receiving therein the asphalt mixture in order to improve the laying efficiency.
- a hopper having a large capacity thereof capable of receiving therein the asphalt mixture in order to improve the laying efficiency.
- more increases in the capacity of the hopper must have been avoided.
- an object of the present invention is to provide an asphalt paver including a hopper mounted on the top end of the asphalt paver and arranged to be closably openable and be foldable so that the hopper may increase the capacity thereof and may permit the overall height of the paver to be lowered to thereby make it possible to improve the efficiency of conveyance of the paver as well as that of the laying operation applied to paving materials.
- an asphalt paver is defined by the features of claim 1.
- the asphalt paver is constructed so that an attachment either for laying a single layer or for laying multiple layers is selectively and removably attached to a base paver provided with a base conveyor for conveying paving materials and supplying the materials onto an applied surface.
- the attachment for laying a single layer is constructed to include a base hopper unit for storing therein the paving materials and for supplying the materials to the base conveyor, and a base screed unit for laying the paving materials supplied by the base conveyor onto the applied surface.
- the attachment for laying multiple layers is constructed to include a hopper unit for lower layer, which stores therein paving materials for the lower layer and supplies the materials to the base conveyor, a screed unit for lower layer for laying the paving materials for the lower layer conveyed and supplied onto the applied surface by the base conveyor, a hopper-conveyor unit for upper layer which is provided with a hopper for upper layer storing therein paving materials for the upper layer and a conveyor for upper layer conveying and supplying, onto the laid paving materials for the lower layer, the paving materials for the upper layer stored in the hopper for upper layer, and a screed unit for upper layer for laying the paving materials for the upper layer, which are conveyed and supplied onto the paving materials for the lower layer.
- the upper layer hopper is constructed to have a pair of left and right buckets, each having a substantially trapezoidal cross-section, which are supported to be closably openable by a support shaft extending in a longitudinal direction of a vehicle body, each of the pair of buckets being constructed to have an upper end capable of being collapsible.
- a single-layer paver or a multi-layer paver may be alternatively constructed by selectively attaching an attachment for either a single layer or multiple layers to the base paver.
- the asphalt paver can be a wide-use apparatus enabling it to achieve cost reduction and to improve working efficiency of the asphalt paver.
- installation of only attachments enables it to achieve simultaneous laying of multiple layers and accordingly, facility investment can be suppressed to the minimum limit of requirement.
- an upper layer is laid immediately after the laying of a lower layer.
- the upper layer will be always laid above the lower layer kept in an unhardened state at a high temperature and therefore, engagement of aggregate can be improved to result in a good bonding of both layers compared with the case where multiple single-layer pavers are employed for individually laying respective one of multiple layers.
- the lower layer can be re-compacted and hardened to exhibit a good degree of compaction and as a result, surface roughness is improved.
- the capacity of a hopper for upper layer can be increased by extending upper portions of buckets of the hopper for upper layer.
- the bottom faces of the buckets can be inclined by closing the buckets so that any residue of paving materials left in the bucket bottom faces might be delivered into delivery channels.
- the upper portion of the rear wall of the hopper for upper layer might be extended upward to a position higher than the other side walls and be collapsible. Due to adoption of such construction, when the paving materials for an upper layer are fed from the front of the asphalt paver while extending the rear wall, the rear wall might be used as a kind of indicator for controlling the work while permitting an operator to perceive a feeling of distance. Therefore, the feeding work of the paving materials can be easy.
- the screed unit for lower layer should preferably be constructed to integrally include a spreader for lower layer for spreading paving materials conveyed and supplied onto an applied surface over the entire paving width, a screed for lower layer for laying the paving materials for the lower layer by applying thereto a compaction, and a spreader for upper layer for spreading paving materials conveyed and supplied onto the paving materials for the laid lower layer over the entire paving width.
- the entire length of the asphalt paver could be reduced so as to improve the weight balance of the paver in the longitudinal direction thereof and to spread respective paving materials for the lower and upper layers over the entire paving width. Therefore, it is possible to control the final thickness of the pavement at a high accuracy.
- the integral provision of the spreader for lower layer, the screed for lower layer, and the spreader for upper layer facilitates mounting and dismounting of the attachment for the laying of multiple layers.
- the above-mentioned screed unit for lower layer should preferably be constructed in a manner such that the screed for lower layer for laying the paving materials for the lower layer is suspended by a hydraulic jack.
- a difference between the height of the laid surface achieved by the screed unit for upper layer and that by the screed unit for lower layer should preferably be detected, and the laid height of the paving materials for the lower layer should desirably be adjusted so that the above-mentioned detected value becomes a predetermined value.

- the hydraulic jack 70E of the screed unit 70 for lower layer is controlled so that the calculated difference between the heights of the laid surfaces becomes a predetermined value, and the height of the screed 74 for lower layer as against the applied surface A is adjusted.
- the height adjustment apparatus is brought into practice by the control unit in the manner of controlling software.
- the described method is achieved by the employment of a contact type sensor, the present invention is not limited to this method, and non-contact type sensor using, for example, infrared and supersonic waves might be employed.
- the construction and arrangement for detecting the difference in the heights between the surfaces laid by the screed 80B for upper layer and the screed 74 for lower layer is not limited to the described one, and as shown in Fig. 10 , the height detection sensor 94 may be supported and secured on the upper surface of the screed 74 for lower layer, via brackets 90 and support 92.
