Description
Technical field
The invention belongs to field of material technology, it relates to the material technology of a kind of traffic facilities, it is specifically related to a kind of asphalt base energy dissipating deceleration railway spike.
Background technology
Along with increasing and the quickening of modern people's rhythm of life of the vehicles, traffic safety problem is more and more serious, therefore in order to effective control lines vehicle speed, road accident rate is reduced, it is often necessary to the object that some forced deceleration facilities reach restriction road speed is installed on road surface.
Forced deceleration facility conventional at present is deceleration strip and vibrations graticule mainly, and wherein deceleration strip comprises cast steel deceleration strip and speed-reducing rubber band. The control effect of these two kinds of deceleration strips is obvious, but also there is certain problem, such as cast steel deceleration strip use cost height, and use for a long time can be pressed into road surface, deceleration decreased effectiveness, not only weather resistance is strong for speed-reducing rubber band, and leaves over, after destroying, the steel nail got off and vehicle tyre can be caused damage. Vibrations graticule is relatively remarkable to the control effect of small-sized vehicle, however for cart particularly high capacity waggon substantially there is no effect. Except above-mentioned two kinds of deceleration measures the most common, the deceleration railway spike material of current motorway also has concrete, epoxy resin. Concrete deceleration railway spike has the features such as intensity height, not easily distortion, but the snappiness of concrete railway spike is poor, and the destruction of driving tire and road surface is bigger; Epoxy resin-matrix railway spike snappiness is better, but non-refractory, about 50 DEG C just start softening transform, but noon in summer, expressway surface temperature can reach more than 60 DEG C, and epoxy resin-matrix railway spike is meeting gross distortion under the rolling of vehicle, loses deceleration effect. Therefore, designing one can either make dolly run at a low speed, it is also possible to the forced deceleration facility allowing cart low gear low speed pass through is very necessary.
Summary of the invention
It is durable in use that the object of the invention is to relate to one, and road pavement and driving threaten deceleration railway spike that is little and that slow down effective to various vehicle energy dissipating and its preparation method.

By such scheme, the pitch that described asphalt adopts is the one in SBS, SBR, EVA, PE modifying asphalt class.
By such scheme, the diameter of described trevira is 15-50um, and length is 6-9mm, and tensile strength is greater than 500Mpa, and fusing point is greater than 250 DEG C.
By such scheme, described ore deposit powder is limestone dust, can by the sieve aperture of 0.075mm.
By such scheme, the described coarse aggregate in asphalt is the one in basalt or diabase.
By such scheme, the described fine aggregate in asphalt is limestone aggregate chips.
By such scheme, described railway spike upper surface is coated with light reflecting material.
The installation of the present invention does not need boring, directly adopts high-performance adhesive to bond. Road surface, location for paste should be dry, clean, without silt, water, grease, dirt. And blow only (clean with acetone brush again) bigger depression place available railway spike glue with pressurized air and repair smooth.
Compared with prior art, the present invention has following major advantage:
Asphalt base energy dissipating deceleration railway spike provided by the present invention, it is strong that officer not only vibrates sense, proves that the vision that it presents is remarkably productive in practice, and forced controlling speed effect is remarkable.
Asphalt base energy dissipating deceleration railway spike provided by the present invention not only can not affect vehicle run stability, and the railway spike that slows down material used is that asphalt has certain shaping and snappiness, can not affect the intensity of vehicle safety parts.
The asphalt not only intensity height that asphalt base energy dissipating deceleration railway spike provided by the present invention adopts, resistance to elevated temperatures is good, and long service life.
