Definitions
- the invention relates to a track ballast for a ballast bed a railway track, especially for railways, consisting of aggregates of different grain diameters, being the mass fraction of the grains that have a grain diameter d> 60 mm, is less than 5% and the Mass fraction of the grains that have a grain diameter d ⁇ 30 mm have greater than 20%.
- ballast bed has a certain intrinsic elasticity, which means that usually vibrations or alternating stresses can be well absorbed from rail transport and at the same time a damping of the on the railway vehicle effective vibrations with what increased driving comfort is connected.
- the ballast track has also proven itself in that it has a high Possesses flexibility and adaptability and in relative can be easily maintained.
- the track ballast used in many cases consists of Aggregates with a so-called "22.4 / 63 mm grain", i.e. it contains - apart from negligible proportions Foreign grain - only aggregate with a grain diameter in the range from 22.4 mm to 63 mm.
- Such Grain distribution has been in the past when used of the track body at speeds ⁇ 200 km / h proven because the ballast bed formed from it on the one hand has a sufficiently high inherent stability and not under the loads of a train traveling over it evades laterally and on the other hand has sufficient elasticity can be achieved.
- the conventional ballast bed is lacking Track position resistance compared to other designs leads to high maintenance costs. This occurs due to the increased due to the high speed Partial overloading of the ballast, resulting in broken gravel and destruction of the gravel structure.
- EP 0 835 958 A2 describes a composition of a Schotters known for a railway track bed, in which the used aggregates a diameter in one area possess from 2 mm to 65 mm, the proportion of the relative small aggregates with a diameter d ⁇ 22.4 mm is approx. 40%, i.e. is very high. As a consequence, that the ballast in its installed state is high Has installation density, but this has the disadvantage that that the frost resistance of the ballast is reduced.
- the invention has for its object a track ballast for a ballast bed of a railway track, in particular to create in a trough-like trough that even at high Speeds under an improved internal load transfer Avoiding stress and settlement peaks.
- the Mass fraction of the grains that have a grain diameter d ⁇ 30 mm have greater than 20% and in particular greater than 30% his.
- the track ballast can be made from any conventional ballast material be formed, but use is preferred of basalt and / or granite and / or gneiss and / or one rock of the same type.
- the grain distribution line of the ballast according to the invention is preferably in a range which is defined by the following range limits: Diameter d of the stone grain in mm Mass fraction of aggregates with a diameter ⁇ d in% in the range from .... to .... 63 99 until 100 56 92 until 100 45 75 to 95 31.5 30 to 60 22.4 0 until 20 16 0 up to 2
- the range limits can be narrowed as follows: Diameter d of the stone grain in mm Mass fraction of aggregates with a diameter ⁇ d in% in the range from ... to ... 63 100 56 95 until 100 45 75 to 90 31.5 30 until 50 22.4 0 to 15 16 0
- the track ballast consists almost entirely of aggregates with a grain diameter in the range from 16 mm to 56 mm, ie has a grain size of 16/56 mm. It has proven to be advantageous if the stone grains are contained in the track ballast according to the following grain distribution (track ballast K1): Diameter d of the stone grain in mm Mass fraction of aggregates with a diameter ⁇ d in% in the range from .... to .... 63 99 until 100 56 92 until 100 45 80 to 90 31.5 46 to 56 22.4 12 until 18 16 0 up to 2
- the grain distribution of this ballast K1 can look as follows: Diameter d of the stone grain in mm Mass fraction of aggregates with a diameter ⁇ d in% 63 100 56 99 45 88 31.5 51 22.4 13 16 1
- the track ballast consists almost entirely of aggregates with a grain diameter in the range from 22.4 mm to 56 mm, ie has a grain size of 22.4 / 56 mm. It has proven to be advantageous if the rock grains are contained in the track ballast according to the following grain size distribution (track ballast K2): Diameter d of the stone grain in mm Mass fraction of aggregates with a diameter ⁇ d in% in the range from .... to .... 63 99 until 100 56 92 until 100 45 78 to 88 31.5 25 to 35 22.4 0 to 1st 16 0 to 1st
- the grain distribution of this track ballast K2 can look as follows: Diameter d of the stone grain in mm Mass fraction of aggregates with a diameter ⁇ d in% 63 100 56 99 45 83 31.5. 30 22.4 1 16 0
- the track ballast consists almost entirely of aggregates with a grain diameter in the range from 22.4 mm to 45 mm, ie has a grain size of 22.4 / 45 mm.
- the rock grains are preferably contained in the track ballast according to the following grain distribution (track ballast K3): Diameter d of the stone grain in mm Mass fraction of aggregates with a diameter ⁇ d in% in the range from .... to .... 63 99 until 100 56 99 until 100 45 92 until 100 31.5. 46 to 56 22.4 3 until 6 16 0 to 1st
- the grain distribution of this ballast K3 can look as follows: Diameter d of the stone grain in mm Mass fraction of aggregates with a diameter ⁇ d in% 63 100 56 100 45 95 31.5 50 22.4 5 16 0th
- FIG Track ballast shown, with three track ballast according to the invention (Track ballast K1, K2 and K3) a conventional one Track ballast are juxtaposed. From the illustration in Fig. 1 it can be seen that the track ballast according to the invention K1, K2 and K3 practically no aggregates with contain a grain diameter d> 56 mm, while corresponding Rocks in the conventional gravel still in a mass fraction of about 8% is included.
- the proportion of grains with one Diameter d ⁇ 31.5 mm compared to the conventional track ballast significantly increased and lies with the invention Track ballast K1 at approx. 51% in the case of the invention Track ballast K2 at about 30% and with the invention Track ballast K3 at approx. 50%.
- FIG. 1 shows individual concrete examples of the grain distribution curves of track ballast
- FIG. 2 shows an area within which the grain distribution curve of a track ballast according to the invention should run.
- the preferred, hatched area is determined by an upper and a lower boundary line, the following parameter values follow: Diameter d of the stone grain in mm Mass fraction of aggregates with a diameter ⁇ d in% in the range from ... to ... 63 100 100 56 95 100 45 75 90 31.5 30 50 22.4 0 15 16 0 0 Lower limit line Upper limit line
