Description
- This is a continuation-in-part of U.S. patent application Ser. No. 11/133,694, filed on May 20, 2005.
- 1. Field of the Invention
- This invention is related in general to the field of construction. In particular, the invention consists of a device and method for improved compaction of asphalt.
- 2. Description of the Prior Art
- Asphalt is a material well-known in the construction industry used to create a surface for supporting vehicles. In this capacity, asphalt is often used to create both parking lots and roads. However, the application of asphalt requires many disparate steps to ensure that the finished surface is both smooth and durable.
- In order to properly apply asphalt, it is necessary that the asphalt be deposited on the intended surface after it has been heated to a high temperature, producing a pliable and workable material. The required temperature for application may vary based on ambient environmental conditions, the intended use of the product, and local regulations. Those skilled in the art of applying asphalt can readily ascertain the appropriate application temperature.
- Once asphalt has been applied, it must be compacted to increase its cohesiveness, to prevent water seepage, and to resist cracking and splitting due to use and changes in its ambient environment. Many methods of compacting asphalt are well known in the art. For example, one method entails the use of large heavy rollers to exert force on the asphalt. However, these rollers not only produce force normal to the surface, but also tend to push the asphalt in front of the roller, forming a ridge or wave of semi-fluid material. In order to reduce this effect, some applications involve rolling newly applied asphalt once or twice and then waiting an extended period of time before rolling the material again. This waiting period extends the time needed to finish the application of the asphalt. Accordingly, it is desirable to have a means for compacting asphalt that reduces or eliminates the wait period inherent in the use of large rollers.
- Another method of asphalt compaction entails utilizing a vibrating plate. This plate is often first pushed over the seams of the newly applied asphalt to seal the material where it meets asphalt that has been previously applied. This is especially useful when the asphalt application is for a patch or repair of previously applied asphalt. Once the edges of the new application has been sealed, the vibrating plate is then passed over the rest of the new application, applying a normal force that increases the cohesiveness and seals the asphalt. Using a vibrating plate eliminates the formation of the pressure ridge encountered when using heavy rollers. Accordingly, waiting periods may not be required between passes using a vibrating plate. However, traditional vibrating plates do not produce compaction levels equivalent to those produced by heavy rollers. This results in most asphalt applications either exclusively using heavy rollers with their corresponding wait periods or first using a vibrating plate followed by the use of a heavy roller. Accordingly, it is desirable to have a device that can produce compaction levels equivalent to those produced by heavy rollers without the associated wait periods and without requiring multiple pieces of equipment.
- The invention disclosed herein utilizes a vibrating plate with one or more secondary surfaces used to concentrate and localize the force applied by the vibrating plate. The newly improved vibrating plate may be either a small push-type model that can be moved and steered by a user or a large, articulated machine. The secondary surfaces may either extend across the width of the primary vibrating plate or may include a dynamic shape and size to increase the compaction effectiveness.
- Another embodiment of the invention includes pneumatic tires for assisting in the compaction of the asphalt. Additionally, the pneumatic tires may provide assistance in steering an articulated machine that includes the above-mentioned vibrating plate with one or more secondary surfaces.
- Various other purposes and advantages of the invention will become clear from its description in the specification that follows and from the novel features particularly pointed out in the appended claims. Therefore, to the accomplishment of the objectives described above, this invention comprises the features hereinafter illustrated in the drawings, fully described in the detailed description of the preferred embodiments and particularly pointed out in the claims. However, such drawings and description disclose just a few of the various ways in which the invention may be practiced.

Referring to figures, wherein like parts are designated with the same reference numerals and symbols,
FIG. 1 is an illustration of a vibratingcompaction device 10 with aprimary compaction plate 12 and asecondary compaction plate 14, according to the invention. Theprimary compaction plate 12 is similar to those well-known in the art of asphalt compaction devices. Amotor 16 or engine provides an up-and-down movement of theprimary compaction plate 12 resulting in a vibration of the plate against the surface of the asphalt. One method of providing this up-and-down movement is to connect an eccentric 17 to themotor 16. A second eccentric 18 may be connected to agenerator 19 which is, in turn, powered by themotor 16. In this manner, two eccentrics having different magnitudes of force may be synchronized. Alternatively, the two eccentrics may be connected by a shaft, with the second eccentric free-turning until it is hydraulically locked to the shaft. Additionally, the use of twoeccentrics - The vibrating
compaction device 10 may be rotated to bring thesecondary compaction plate 14 in contact with the surface of the asphalt. In this embodiment of the invention, the secondary compaction plate is the same width as theprimary compaction plate 12 but has a smaller length resulting in a small footprint. Themotor 16 continues to produce a force equivalent to that normally applied through the primary compaction plate. However, since the footprint of the secondary compaction plate has a smaller contact area, the force exerted by the vibratingcompaction device 10 is concentrated into a smaller area. In this manner, the ability of the vibratingcompaction device 10 to compact the asphalt is increased, resulting in a higher compaction rate than can be achieved using theprimary compaction plate 12. - Alternatively, the
primary compaction plate 12 may be integrated with thesecondary compaction plate 14 to form a unified compaction plate with a first and second surface. Here, the second surface is affixed to the first surface in a manner that forms a 135 degree angle between the two surfaces. However, the invention is not limited to any specific angle and may include an angle equal to or greater than 90 degrees and less than or equal to 180 degrees. -
FIG. 1 also illustrates atertiary compaction plate 20. In this embodiment of the invention, thetertiary compaction plate 20 has a width which is less than that of theprimary compaction plate 12. Additionally, the tertiary plate may be formed in the shape of a semi-circle, an ellipse, a free-form shape, a triangle, or other polygon. Because the surface area of thetertiary compaction plate 20 is less than that of theprimary compaction plate 10 and the secondary compaction plate, thetertiary compaction plate 20 may be used to apply even more force to the surface of the asphalt, thus increasing the rate of compaction. The non-traditional shape of thetertiary compaction plate 20 may be used to concentrate the force of the vibratingcompaction device 10 along a focused path, such as a seam or newly filled-in trench. In an alternate embodiment of the invention, the secondary compaction plate may also include a non-traditional shape such as a semi-circle, ellipse, free-form shape, triangle, or other polygon. Additionally, theprimary compaction plate 10 may include a plurality of surfaces including a primary, secondary, and tertiary surface. The angle formed by the tertiary surface and the primary surface may be greater than or equal to 90 degrees and less than or equal to 180 degrees. -
FIG. 2 is an illustration of a vibratingcompaction device 10 with asecondary compaction plate 14 that can be extended and retracted with respect to theprimary compaction plate 12. In this embodiment of the invention, the width of thesecondary compaction plate 14 is the same as that of theprimary compaction plate 12. However, thesecondary compaction plate 14 may assume any width, either less than, equal to, or greater than that of the primary compaction plate. Likewise, while this embodiment of the invention includes a rectangularsecondary compaction plate 14, thesecondary compaction plate 14 may assume any shape. The result is that thesecondary compaction plate 14 may be extended away from the primary compaction plate resulting in a focused application of the vibrating compaction device's downward force. Additionally, thesecondary compaction plate 14 may be retracted so that its application surface (side facing the asphalt) is flush with or recessed above that of the primary compaction plate. -
FIG. 3 is an illustration of an articulated vibratingcompaction device 100 with a pair ofprimary compaction plates 112 and asecondary compaction plate 114, according to the invention. In this embodiment of the invention, the articulatedsegments 115 are used to steer the articulate vibrating compaction device. A firstprimary compaction plate 112 a may be rotated that thesecondary compaction plate 114 is applied to the surface to be compacted, as illustrated inFIG. 4 . Additionally, the articulated vibratingcompaction device 100 may include additional secondary compaction plates ortertiary compaction plates 118. -
FIG. 5 is an illustration of an articulated vibratingcompaction device 100 with asecondary compaction plate 114 that can be extended and retracted with respect to one of theprimary compaction plates 112. While this embodiment of the invention includes a rectangularsecondary compaction plate 114, thesecondary compaction plate 114 may assume any usable shape. The result is that thesecondary compaction plate 114 may be extended away from the primary compaction plate resulting in a focused application of the vibrating compaction device's downward force. Additionally, thesecondary compaction plate 114 may be retracted so that its application surface (side facing the asphalt) is flush with or recessed above that of the primary compaction plate. - Yet another embodiment of the invention is illustrated in
FIG. 6 . Here, an articulated vibratingcompaction device 200 includes aprimary compaction plate 202 connected to aneccentric roller 204 located in a first articulatedsegment 206. As theeccentric roller 204 rotates, it imparts an up-and-down movement to theprimary compaction plate 202 resulting in a vibration of the plate against the surface of the asphalt (not shown). A user may steer the articulated vibratingcompaction device 200 by rotating the first articulatedsegment 206 relative to a second articulatedsegment 208. Locomotion is provided by a pulling motion of theprimary compaction plate 202 as it is eccentrically vibrated. - A first set of
pneumatic tires 210 may be placed adjacent to the primary compaction plate. These tires may provide compaction of the asphalt adjacent to the area being compacted by theprimary compaction plate 202. Additionally, these tires may prevent asphalt which is being compacted by the primary compaction plate from spreading away from the sides of the primary compaction plate. This prevents a bow wave of asphalt from forming along the sides of the path of the articulatedvibration compaction device 200. Additionally, this first set ofpneumatic tires 210 may assist in steering the articulated vibration compaction device. - The articulated vibrating
compaction device 200 may include asecondary compaction plate 212 which can be rotated so as to come in contact with the surface of the asphalt. In this embodiment of the invention, the secondary compaction plate is the same width as theprimary compaction plate 202 but has a smaller length resulting in a smaller area of compaction, while theeccentric roller 204 continues to produce a force equivalent to that normally applied through theprimary compaction plate 202. However, since the footprint of the secondary compaction plate is smaller, the force exerted by the articulated vibratingcompaction device 200 is concentrated into a smaller area. In this manner, the ability of the articulated vibratingcompaction device 200 to compact the asphalt is increased, resulting in a higher compaction rate than can be achieved using theprimary compaction plate 202. - In one embodiment of the invention, the
primary compaction plate 202 may be integrated with thesecondary compaction plate 212 to form a unified compaction plate with a first and second surface. Here, the second surface is affixed to the first surface in a manner that forms a 135 degree angle between the two surfaces. However, the invention is not limited to any specific angle and may include an angle equal to or greater than 90 degrees and less than or equal to 180 degrees. - A second set of
pneumatic tires 214 may be included in the second articulatedsegment 208. This second set of tires may be used to provide auxiliary compaction. Additionally, the second set of tires may assist in the steering of the articulated vibratingcompaction device 200. In yet another embodiment of the invention, a second primary compaction plate, with or without another secondary compaction plate, may be included in the second articulated segment as well. - Those skilled in the art of making asphalt compaction systems may develop other embodiments of the present invention. However, the terms and expressions which have been employed in the foregoing specification are used therein as terms of description and not of limitation, and there is no intention in the use of such terms and expressions of excluding equivalents of the features shown and described or portions thereof, it being recognized that the scope of the invention is defined and limited only by the claims which follow.
