Definitions

  • This invention relates to apparatus, in particular a road-surfacing vehicle, and to a method for surfacing substrates such as roads.
  • the screeding contact surfaces are difficult to maintain in a clean condition.
  • the practice of heating them, which is conventionally used for hot materials, would be counter-productive and likely to increase the problem. It has been found that any non-uniform build-up causes the new surface to be gouged longitudinally, and causes transverse unevenness.
  • the present invention is based on an appreciation of the problems described above, and on the realisation that the dragging effect is caused by the forces generated in the materials resulting from the different relative velocities of the substrate and the screed plate with respect to the material sandwiched in between, for a given compaction coefficient.
  • the novel solution is to provide a screed that, while continuing to define the contour of the surface (flat or curved), is movable relative to the vehicle/applicator, and opposite to the direction of travel of the applicator.
  • the screed moves at the same or similar velocity as the substrate (road) and in the same relative direction.
  • the material contact zone of the screed should be maintained free of any material build-up; for example, the screed may be lubricated or scraped in such a way that either the surfacing material does not attach to it, or is periodically removed.
  • a convenient and preferred loss motion solution to both given problems of the prior art is to make the screed in the form of a roller.
  • the invention may be described below with reference to rollers.
  • other loss motion principles although perhaps more complicated, may also perform the same task, such as an endless belt or an oscillating mechanism. It is recognised that, as there is a frictional force at the interface between the screed and the material, some form of horizontal compaction could result if the relative velocity of the screed was greater than that of the substrate.
  • Simple scrapers may be applied to rollers, to prevent material pick-up.
  • Water jets may be provided, in order to lubricate the surface of the screed, to either augment or replace the scraper system.
  • the roller is preferably provided in an arrangement that accommodates a road camber. This is preferably achieved by dividing its length into two or more sections such that it can be deformed along its length, without creating marks in the road surface. If, for example, the laying box is more than 3 m wide, three coaxial roller sections may be used.
  • the respective parts of the roller are preferably connected by means of a hinge support bearing, e.g. with constant velocity drive coupling. If desired, the respective parts may be driven independently, e.g. in order to facilitate the surfacing of road corners.
  • the speed of roller rotation may be controlled and maintained so that it is be governed by the forward speed of the applicator. This may be either by mechanical means or by a fluid motor controlled by an electro-hydraulic servo control system with or without feedback.
  • the thickness of the applied surfacing may be varied by raising or lowering the rollers.
  • the quantity of material supplied to the roller may be controlled, e.g. by means of a conventional strike plate set at a height which will limit the upward climbing force on the roller. This force will be less than that required to lift the thickness-controlling skids off the substrate, and may be controlled by adjusting the compaction coefficient C/C1.
  • Means may also be provided, in order to vibrate the roller. This enhances consolidation of the material.
  • Fig. 1 shows a substrate 1 and that part of a conventional applicator comprising a fixed screed 2 and associated strike plate 2a, travelling at a velocity V2 relative to the substrate.
  • the compaction coefficient is given by C/C1.
  • a surfacing composition 3 is deposited between the substrate 1 and the screed 2 by trailing application.
  • the arrows 4 indicate the horizontal forces generated in the material due to the moving screed, and the arrows 5 indicate allowable vertical movement of the screed 2.
  • Figs. 2 and 3 are provided for direct comparison with Fig. 1. Instead of the screed 2, there is a roller 6 or an endless belt 7 mounted on rollers 8, respectively, driven at a velocity V1.
  • the arrows 9 and 10 respectively indicate vertical and horizontal compaction. In both of the cases illustrated in Figs. 2 and 3, V1 and V2 are approximately the same.
  • Fig. 4 like Fig. 2, shows a substrate 1, a strike plate 2a and a roller 6.
  • a roller drive motor 11 is shown in this case, and is connected to the roller 6 by means of a belt 11a.
  • a scraper 12 For the purposes of cleaning the roller from surfacing composition 3 that is picked up, there are a scraper 12 and a water sprayer 13.
  • Fig. 4 also shows a laying box illustrated generally at 13, including paddles 14 and an auger 15.
  • Fig. 5 shows a Micro Asphalt laying box incorporating a rolling strike plate as described above.
  • the laying box is constructed in conventional fashion and is hinged on the centre line 21 to accommodate any road camber.
  • the two sides of the laying box are the same but of opposite hand.
  • Skids 22 maintain the laying box altitude with respect to the substrate, and also reduce the reproduction of substrate imperfection in the newly formed surface.
  • the mixed material is delivered to the laying box on the box centre line 21 and midway between the agitation paddles 23 and a distribution auger 24 whose speed and direction of rotation can be altered via a fluid drive system 25.
  • a screw or fluid power adjustor 26 is used to vary the height of the box structure above the substrate and so vary the thickness of the applied material.
  • a roller 27 is also hinged, by means of a support bearing with constant velocity drive coupling, on the centre line 21.
  • the roller 27 is provided with its own fluid drive system 28 which enables the roller's rotational speed to be accurately controlled in relation to the forward velocity of the applicator.
  • the roller 27, and its constituent parts 27a and 27b, are shown in more detail in Fig. 6, where the coupling is shown at 30.
  • the height above the substrate of a strike plate 29 can be independently adjusted, to enable the head of material presented to the strike roller to be varied and so vary the compaction coefficient C/C1. Likewise the height of the strike roller 27 above the substrate can be varied, which controls the thickness of the applied material.
  • the strike roller height adjustment will also adjust the height of the strike plate 29, as the two are mechanically linked.
  • the head of material presented to the strike roller 27 will thus be maintained for any strike roller setting, so varying the compaction coefficient C/C1.
  • the roller speed can be controlled manually or using a ground speed-related electro-hydraulic system similar to that used on conventional road construction or agricultural equipment.
  • Tests were also conducted using two coaxial rollers, driven independently, with one roller rotating faster than the other.
  • the roller rotating faster produced a surface with a lower surface texture depth of 1.8 mm compared with a surface texture depth of 2.55 mm for the slower roller, indicating that some horizontal, as well as vertical, compaction was taking place at the surface.
