Definitions

  • This invention relates to an apparatus for working road shoulders. More particularly, this invention relates to an apparatus for working road shoulders comprising granular aggregate materials.
  • Paved and concrete roadways are typically provided with shoulder regions which provide sufficient space to enable vehicles to safely pull off from the roadways for various reasons such as emergency repairs, driver and passenger rest, and parking.
  • Road shoulders are typically supplied in the form of granular aggregate substrates such as gravel, crushed rock, sand, pebbles, crushed shells, crumbed waste rubber and other such materials and mixtures of such materials.
  • Road shoulders comprising such granular aggregate materials must be significantly compacted in order to provide suitably dense matrices to support the weights of vehicles as they transition under some speed from the hard road surfaces to the road shoulders.
  • the shoulder regions are prepared and worked by dispensing fresh aggregate materials adjacent the road surfaces after which, the road shoulders are worked to draw the aggregate materials against the road surfaces, then smoothed or groomed, and finally compacted by specialized equipment such as motor graders and self-propelled vibratory compacting rollers.
  • Freshly worked and distributed road shoulders are typically very soft and susceptible to forming deep ruts caused by the wheels of equipment used for the initial grooming steps thereby resulting in uneven compacting and poor shoulder stability after compacting has been completed.
  • the grooming steps often require the mouldboards of motor graders to move spilled or excess granular substrates from the surfaces of newly paved or poured road surfaces to the shoulders thereby often causing gouging, tearing or ripping of the newly paved or poured road surfaces which significantly reduces their durability and longevity.
  • Attempts to solve these problems include the development of devices mountable onto dump trucks or specialized self-propelled equipment as exemplified in US Patent Nos. 5,304,013, 6,164,866, and 6,612,774, for creating and working road shoulders without requiring the trucks or equipment to leave the road surfaces.
  • Road shoulders are typically positioned adjacent to man-made ditches or gullies to facilitate water egress from the road surfaces.
  • excessive rainfalls often result in the formation of rapidly flowing water channels that cut crevices and fissures into road shoulders thereby causing losses of the granular aggregate substrates into the ditches and gullies resulting in destabilization and deterioration of the road shoulders, thus creating hazardous conditions for vehicles transitioning from the road surfaces to the shoulders. Consequently, such road shoulders require regular periodic maintenance with specialized equipment to reclaim road shoulder substrates washed away into adjacent ditches and gullies, followed by their recycling back onto the road shoulder portions which are then reformed and compacted.
  • road shoulder substrates which have washed away into adjacent ditches and gullies may be recovered and transferred onto the road surface by a motor grader equipped with a gang of disc harrows as exemplified in U.S. Patent No. 5,810,097, and then transferred back to the road shoulder portion by the grader mouldboard.
  • the reclaimed road shoulders may then be worked and groomed by various types of devices as taught by U.S. Patent Nos. 4,156,466 and 5,332,331, after which the groomed road shoulders may be compacted.
  • such road shoulder reclaiming and reforming operations require at least two or more specialized self-propelled equipment such as motor graders that are provided with selected demountable devices adapted for working road shoulders wherein each operation is performed in a separate pass.
  • Another problem often encountered during road shoulder reclaiming operations is caused by the presence of debris or alternatively, vegetation that commonly establishes and proliferates at the outer margins of road shoulder surfaces and along their side edges sloping into the adjacent ditches and gullies.
  • debris and vegetation are typically pulled in clumps onto road surfaces during the shoulder recovery operation, then re-distributed across the new shoulder surfaces formed as the granular aggregate materials are transferred back to the road shoulder regions, and then compacted into the newly formed road shoulders.
  • the presence of debris and/or clumps of vegetation on and in newly worked road shoulders results in uneven compaction thereby resulting in unstable road shoulders that quickly deteriorate and subsequently, more frequently require costly and time-consuming road shoulder reclaiming and grooming operations.
  • the exemplary embodiments of the present invention are directed to the working, grooming and compaction of road shoulders.

  • the height of the worked road shoulder provided by the augured leading roller 52 may be controllably adjusted with an optional road shoulder height adjusting apparatus 90.
  • the following smooth-faced roller 56 will compact the groomed road shoulder. We have found that providing an upwardly inclined slope of granular aggregate material on the road shoulder region immediately adjacent the edge of the road surface prior to compacting results in a very densified portion of road shoulder immediately adjacent the road surface after compacting.
  • Such a densified road shoulder portion facilitates safer egress of vehicles onto the road shoulder region at speed and also, is more resistant to damage caused by heavy rainfalls and weathering.
  • an optional packing wheel assembly 73 may be provided in front of the road-shoulder grooming component 50. After the road shoulder working, grooming and compacting operations are completed, the four components are raised, then the first and third components are laterally retracted for transport. It is to be understood that the individual components comprising the road shoulder working, grooming and compacting apparatus 15 of the present invention are useful when used alone and therefore it is within the scope of this invention, for example, to demountably couple the road-shoulder grooming component 50 to the rear of a suitable machine for grooming and compacting road shoulders.

Abstract

La présente invention concerne un dispositif permettant de compacte, de damer et de façonner des accotements, lequel dispositif est conçu pour être relié de manière amovible à des machines autotractées commandées par un opérateur. Le dispositif comprend un premier composant conçu pour façonner de manière commandée une portion extérieure d'une zone d'accotement afin de pousser des matériaux agrégés granuleux vers et sur une surface de route, un second composant placé après le premier composant et mobile verticalement entre des positions dégagée et engagée afin de transférer de manière contrôlée le matériau agrégé granuleux depuis une surface de route vers un zone d'accotement, et un troisième composant placé après le second composant de manière à permettre la distribution, le compactage et le damage des matériaux agrégés granuleux contenus dans la zone d'accotement. Le premier composant et le troisième composant sont mobiles entre des positions rétractées relevées et des positions abaissées latéralement déployées afin d'entrer en contact et de façonner les zones d'accotement pendant que la machine autotractée commandée par un opérateur se déplace le long de la surface de route. Un quatrième composant est éventuellement placé entre le second composant et le troisième composant de manière à brosser les surfaces de route.
