Definitions

  • pre-manufactured slabs were placed directly on the ground as the slab distributes the load of the vehicles to such an extent that the specific pressure on the ground is not so big that the slabs are pressed down in it. These slabs have, however, been used only for provisional airports as a more intensive trafiic will soon bring the individual slabs out of position and especially out of level.
  • the purpose of the invention is to remedy these drawbacks by ridding the touchy parts of the road completely of the freezable stratum.
  • the road construction according to the invention is characterized in that the pro-manufactured slabspossibly by means of girdersrest on the rows of frost-proof piles or pillars (e.g. of concrete) placed there in advance and reaching down through the freezable stratum and anchored in solid and frost-free strata whereas the slabs are kept free of the freezable stratum. Therefore, they will not be displaced when the frozen stratum thaws and the other parts of the road are not in contact with the frozen stratum and will, consequently, not be offset by it.
  • Each slab can be supported at three or more points, or along the sides, as it rests on girders which again rest on the piles or the pillars, and in order to prevent the slabs from being displaced horizontally they may each, according to the invention, have supporting projections along the vertical sides of the pillars, such as arms or collars.
  • the slabs may, according to the invention, have, further to the faces bearing against the pillars, at least one projection turning downwards and e.g. being calotte-shaped and resting on the ground.
  • the last-mentioned projection contributes in the support of the slabs, but resting on the surface of the ground it will not freeze together with the freezable stratum but will in the lateral direction be secured by the pillars.
  • they may, according to the invention, have bracing ribs from one of the two kinds of projections to the other.
  • bracing ribs can be placed in such a manner that they can also transfer the main part of the horizontal forces in the slabs as, according to the invention, the ribs are positioned so that they stretch mainly from horizontal supporting projections along the edge of the slabs to a centrally positioned vertical supporting projection under the centre of the slabs.
  • each slab may have an electric heating element built-in and connected to electric cables in the side of the road.
  • the road can be kept frost-free, and snow and ice covering the road will thaw without the assistance of any snow-clearing service. It is often impossible for such a service to do its work fast enough, and in many countries it does not operate on Sundays and holidays. Ditches and other measures for drainage of the road are superfluous, as its underside will always be kept dry by the wind which may pass freely under it.
  • the narrow space between the slabs, the so-called expansion joints, may be filled in some known way with asphalt or other water-tight substances or organs so that precipitation will drain off over the lateral edge of the slightly curved roadway.
  • each slab may during the manufacturing process be furnished with a wearing surface insulating against moisture, and this insulating layer may be applied with greater care and under more ideal conditions at a factory where this preparation can take place indoors and more conveniently by the aid of the requisite machinery than on site. Furthermore, the preparation as well as the finishing preparation can take place without the usual pressure of the traffic which leaves the least possible time for road works.
  • the slabs should, according to the invention, meet this demand by the trafiic fully, as they are not repaired but renewed.
  • road side fences may, according to the invention, be clamped to the sides of the slabs or be made as constituent parts of the roadway element.
  • the individual roadway element may be assembled to larger units, e.g. by means of cables passed through cable ducts in the roadway elements so that the cables run parallel with or diagonal to the longitudinal direction of the roadway, by means of spigot-and-socket joining of steel reinforcement, by means of bolting, or in some other known manner.
  • FIG. 1 shows part of a road construction in perspective
  • FIG. 2 shows, also in perspective, a slab forming part of the same construction and FIG. 3 shows the same slab seen from below in a slanting position.
  • Each slab has a hole 7 in the centre of its overside in which there is a ring 8 by means of which the slab can be lifted from its place.
  • the underside of the slab is equipped with a number of ribs 9 for bracing. These ribs stretch from the edge of the slab towards a calotte-shaped projection 10 in the centre of the slab.
  • the slab can rest on the ground by the aid of this projection, but this must not necessarily be so.
  • the slab which is finished at the factory, has an electric heating element built into its surface coating, consisting of a material insulating against moisture, or immediately under this coating, and the heating element is connected electrically with cables 11 in an external cable box 12 on the fence 4.
  • Such pre-manufactured slabs can be richly varied with regard to surface equipment.
  • they can be equipped with grouted in road stripes, marking of pedestrian crossings, acoustic road marking in the form of transverse grooves of varying size, etc., just as it will be possible to make the surface granulated or grooved or in some other way skid-proof.
  • the advantage of the road construction is, according to the invention, first and foremost that the nature of the ground is of no importance and that generally it will not be necessary to move any earth before the road is constructed.
  • the road can be constructed across areas fiooded part of the year. Drainage or sewerage is not necessary.
  • the water runs off the roadway at the side fence 4 which has vertical grooves 13 on its inside to ensure the drainage.
  • the road is easy to repair. Repairs are effected simply by renewing one or more slabs 3. Thus the periods during which the roadway is blocked to the trafiic are limited to a minimum.
  • the underside of the road is kept dry by the wind and is therefore not exposed to decomposition.
  • Rainwater may, furthermore, drain off through the intervals 14 between the slabs 3, but generally it will be preferred to fill the expansion joints with asphalt so that the overside of the roadway forms a water-tight whole.
  • the piles 1 are introduced in holes in the transverse supports 2. Instead these supports can be laid in grooves on top of the piles 1 or the piles may have vertical guide pins introduced in holes in the supports 2.
  • each slab 3 Under the middle of each slab 3 sand or pebble gravel can be spread over the ground in advance in support of the calotte-shaped part of the slab.
  • a roadway construction comprising piles extending into the ground sufficiently below the frost line to provide road support and having upper end portions extending above the ground surface, beams supported on the upper ends of said piles and extending transversely of the roadway at selected spaced intervals, said beams having a rectangular cross section with fiat upper surfaces and opposed vertical side surfaces, a plurality of rectangular premanufactured concrete slabs each having a length slightly less than the center-to-center spacing of said beams and a width which is a unit fraction of the width of the roadway, each of said slabs extending between and being supported by two successive beams and having end portions which are notched to provide fiat lower surfaces resting on the flat upper surfaces of said beams and vertically downwardly extending shoulders engagable with said side surfaces of said beams, a plurality of said slabs being laid side-by-side to make up the desired width of the roadway, said slabs having on their under sides downwardly projecting integral ribs extending generally lengthwise of said slabs and having vertical end faces which are coplan
  • said means for confining said slabs at the sides of the roadway comprises curbs extending longitudinally of the roadway at each side thereof and projecting above said slabs and piles supporting said curbs above the ground and extending into the ground sufficiently below the frost line to provide permanent support.
  • each slab is formed in its upper face with a central recess and in which a lifting ring for said slab is anchored in said recess.
