Abstract
A method for placing an audible feature on a road includes heating a composition and depositing the composition onto at least one of a surface of the road and an existing layer on the road. The composition seeps into porous areas of at least one of the surface of the road and the existing layer on the road and cools to form the audible feature. The audible feature adheres to at least one of the surface of the road and the existing layer on the road.
Description
- The present disclosure relates generally to the field of road features. More particularly the disclosure relates to systems and methods for placing audible road features or visible audible road features.
- Roadway boundaries are delimited by visual markings, for example, paint or ribbon that bonds to the road surface. Such visual boundaries may reflective to aid a driver in seeing the road boundaries. In addition to visual markings, roadway boundaries may also be delimited by audible features that produce an audible noise if a vehicle tire passes over or strikes them. Such audible features include rumble strips, Bott's dots, cat's eyes, plastic or thermoplastic markings, etc.
- Plastic or thermoplastic audible markings may be placed onto a visual marking (e.g., ribbon) when the visual marking is laid onto a new or existing road surface and is still hot. The cool audible marking is placed onto the hot visual marking and bonds with the visual marking as it is placed on the road. Such conventional processes for placing audible markings require removal of old visual markings and placement of new visual markings with the audible markings and thus have a high cost. What is needed is a system and method for placing audible markings onto an existing road surface or onto an existing visual marking. What is also needed is a system and method for placing audible markings in a more cost effective manner.
- One exemplary embodiment of the invention relates to a method for placing an audible feature on a road. The method includes heating a composition and depositing the composition onto at least one of a surface of the road and an existing layer on the road. The composition seeps into porous areas of at least one of the surface of the road and the existing layer on the road and cools to form the audible feature. The audible feature adheres to at least one of the surface of the road and the existing layer on the road.
- Another exemplary embodiment of the invention relates to a method for placing an audible feature on a road using a hydrostatic pump and a depositing device mounted on a vehicle. The method includes heating a composition to a liquid state and depositing the composition onto at least one of a surface of the road and an existing layer on the road using the pump and depositing device. The composition bonds with at least one of the surface of the road and the existing layer on the road and cools to form the audible feature.
- Another exemplary embodiment of the invention relates to a system for mounting on a vehicle and configured for placing an audible feature on a road. The system includes a heating element configured to heat a composition, a hydraulic pump, and a depositing device configured to receive the composition from the hydraulic pump. The depositing device is configured to cut portions of the composition and provide the portions onto at least one of a surface of the road and an existing layer on the road. The portions of composition bond with at least one of the surface of the road and the existing layer on the road and cooling to form the audible feature.
- It is to be understood that both the foregoing general description and the following detailed description are exemplary and explanatory only, and are not restrictive of the invention as claimed.
- These and other features, aspects, and advantages of the present disclosure will become apparent from the following description, appended claims, and the accompanying exemplary embodiments shown in the drawings, which are briefly described below.

FIG. 7 is a flow diagram of a method for placing an audible feature on a road, according to an exemplary embodiment. -
FIG. 8 is a flow diagram of a method for placing an audible feature on a road, according to another exemplary embodiment. - Before describing in detail the particular improved system and method, it should be observed that the invention includes, but is not limited to, a novel structural combination of conventional mechanical and electromechanical components and not in the particular detailed configurations thereof. Accordingly, the structure, methods, functions, control and arrangement of conventional components have generally been illustrated in the drawings by readily understandable block representations and schematic diagrams, in order not to obscure the disclosure with structural details which will be readily apparent to those skilled in the art, having the benefit of the description herein. Further, the invention is not limited to the particular embodiments depicted in the exemplary diagrams, but should be construed in accordance with the language in the claims.
- Referring generally to the figures, a system and method for placing audible road features is shown. The system can include a composition, a heating element, a pump, and a depositing device. The system may place or deposit the heated composition onto an existing roadway or existing visual marking using the pump and depositing device. As the heated composition cools, it bonds with the existing roadway or existing visual marking and forms an audible feature on the roadway. The composition may also include reflective markings to make the audible feature more visible. The system may be placed or mounted onto a vehicle to facilitate placement of the audible features on the roadway as the vehicle moves.
- Referring to
FIG. 1 , avehicle 100 includes asystem 102 configured to placeaudible features 104 onto aroadway 106 according to an exemplary embodiment. In the illustrated embodiment,system 102 deposits audible features 104 onto avisual marking 108.Visual marking 108 may be paint, a ribbon, epoxy, asphalt, concrete, or another material bonded toroadway 106.Visual marking 108 may be reflective or non-reflective. It is noted that according to other exemplary embodiments,audible feature 104 may be deposited directly onto a surface ofroadway 106.Audible feature 104 is raised from the surrounding surface ofroad 106 or marking 108 and thus if a vehicle drives over feature 104 (e.g., a tire passes over or strikes feature 104) an audible sound is produced.Feature 104 may also have reflective properties to the boundaries ofroad 106 easier to see. - Conventional systems may only be capable of depositing audible features onto a visual marking when the visual marking has just been laid and is still hot. In order to add reflective or audible markings to the road, such systems require that the old visual markings be removed (e.g., by milling, by water pressure, etc.) and new visual markings be laid with the audible features. In contrast,
system 102 heats a composition and deposits the composition using a pump onto a cool surface ofroad 106 or onto a cool surface ofvisual marking 108. The composition may include thermoplastic materials, epoxy materials, urea plastic materials, preform thermoplastic materials, rubber materials, metal materials, and/or any other material. When the composition cools, it bonds with the surface ofroad 106 or the surface ofvisual marking 108 to formaudible feature 104. By depositingaudible feature 104 in such a manner, the cost of adding audible features to a roadway may be greatly reduced. - While
