Definitions
- the invention relates to a method for laying rails in a pavement having a road surface for traffic, wherein the rails are laid in the pavement such that they are sunken with respect to the road surface according to the preamble of claim 1.
- European Patent Application EP-A 0 737 778 in the name of the Applicant discloses a rail track construction with which two parallel rails are laid in grooves in a concrete or steel foundation.
- a layer of sound-absorbent material such as, for example, very open asphalt concrete (VOAC) is applied between and alongside the rails. How the rails are fixed in the grooves is not shown in more detail. Fixing of the rails is problematical since, on the one hand, a high degree of fixation is desired and, on the other hand, a sound-damping effect must also be obtained and the transfer of vibration from the rails to the foundation, which for example is made of concrete, must be restricted.
- VOAC very open asphalt concrete
- EP-A 0 737 778 is not suitable for use in a road surface for traffic, such as, for example, in the case of tram rails laid in the road.
- NL patent 36958 discloses a method according to the preamble of claim 1. A rail structure comprising rails and cross members is positioned after which the area in between is filled.
- One aim of the present invention is therefore to provide a method for laying rails in a pavement with which stable positioning of the rails can take place in a simple and inexpensive manner.
- a further aim of the present invention is to provide a method for forming a rail construction which is well integrated in the paving construction of the pavement with relatively few transitions so that a level road surface is retained.
- a further aim of the present invention is to provide a rail construction wherein adequate vibration damping of the rails is obtained, wherein fixing of the position in the long term under static loads is guaranteed and wherein in the event of replacement the rails can be removed relatively easily.
- the method according to the present invention has the characterising features of claim 1.
- the layer of starting material When applying the layer of starting material the latter can be rendered plastic and applied simply with the aid of, for example, known asphalt spreading techniques.
- the voids in the starting material are then filled with a hardening reinforcing medium so that a fixing course is formed which has very high lateral dimensional stability.
- the rails are accurately fixed and sleepers, tie bars or other fixing means to join the rails to one another can be dispensed with.
- the method according to the present invention saves costs because the major part of the rail construction is formed by the road paving.
- the space between the rails and the wall of the grooves is filled with a casting material, such as a casting material based on plastics, optionally with vibration-damping fillers, or a casting material composed of asphalt.
- a casting material such as a casting material based on plastics, optionally with vibration-damping fillers, or a casting material composed of asphalt.
- the staring material used for the fixing course is very open asphalt concrete (VOAC) having a voids content of at least 20 %, preferably between 25 % and 30 %. It has been found that such a course allows good penetration of the hardening reinforcing medium and that a highly advantageous lateral dimensional stability is obtained by this means.
- the reinforcing medium comprises a cement-based slurry which has good penetration in very open asphalt concrete.
- the thickness of the fixing course is preferably between 5 cm and 15 cm and in a preferred embodiment forms the road surface for the traffic.
- a roadbase comprising asphalt granulate cement formed from recycled asphalt concrete with cement (CRAC) and/or asphalt concrete with minerals such as crushed aggregate or chippings (for example RAC) is preferably used.
- CRAC recycled asphalt concrete with cement
- a basecourse of asphalt concrete with minerals (RAC) can be used on top of this foundation and the fixing course applied on top of this.
- transverse forces of various magnitude such as, for example, transverse forces which arise when taking bends, can be absorbed by varying the thickness of the fixing course.
- the thickness of the roadbase is partly dependent on the sub-grade conditions and on the volume of traffic.
- FIG. 1 shows a diagrammatic cross-section of a tram rail construction according to the present invention.
- the figure shows a tram rail construction 1 having two rails 2, 2'. each of which has been laid in an individual groove 3.
- the groove 3 has been made in a fixing course 4 according to the present invention which has been formed from very open asphalt concrete with a hardened cement-based reinforcing medium therein.
- the fixing course 4 forms a road surface 5 for traffic, the rails 2, 2' being laid flush with the road surface 5.
- the rails 2. 2' have been fixed in the grooves 3 by means of a plastic casting material 6, which, for example, is formed from a plastic, optionally with vibration-damping fillers.
- a plastic casting material 6 which, for example, is formed from a plastic, optionally with vibration-damping fillers.
- a roadbase 8 is used below the basecourse 7, which roadbase 8 can have a composition similar to that of the basecourse 7 or can be formed from crushed used asphalt concrete to which about 4 % by wt cement has been added (CRushed Asphalt Cement or CRAC) which has been made up in accordance with generally known guidelines.
- rails can be laid in a pavement in a simple manner, without using sleepers, tie bars or other fixing means, such that a rail construction is obtained that is well integrated in the road surface with a minimum of transitions and minimum unevenness.
- the rails 2, 2' can be anchored in a stable manner without the use of sleepers or other tie elements between the rails.
