TRACK PAVEMENT.
Application fled February 18, 1927. Serial No. 169,343.
-My invention relates to track pavement, that is,'to pavements, arranged between track rails or ad acent to track rails. As is known, heretofore pavements adjacent to track rails,
l and pavement between track rails as in the case of railroad crossings, have been constantly replaced at great expense with considerable annoyance to the public and obstruction to trafiic. I have sought to provides track pavement which will absorb or dissipate the causes of the trouble and provide a pavement of long life, greater efficiency and one having a low maintainance cost.
My track pavement and crossing permits easy access to the track rails, tends to ex.-
clude water and frost, is easily installed, being preformed in a factory and delivered ready to lay, is easily renewed in whole or in part,
forms substantially a single unit of the track so and pavement, is very quite, absorbing and dissipating within its structure vibrations and noise. My construction provides a non-warping trafiic surface with corresponding reduction of danger which arises when the ordinary construction is used. My construction also provides a protection to the automatic train control systems and to the si nal control systems, especially those using e ectricity.
In the drawings Figure 1 is a cross section of my track pavement and Figure 2 is a longitudinal section of Fig. l on the line ill-eel.
Figure 3 is a modification of 1.
- in the drawings 1 have shown in Figures 1. and 2 the preferred form of my track pave ment tor a railroad crossing-1, 1, are the track rails; 22, 9. are the rail ties laid in usual manner; 3, 3 are rail tillers formed to conform to the rail on each side as shown, 'i'illing the s ace in the rail below the ba l These rail 1118115 3, 3 may be, if desire provided with a flange way l shoulde is provided on the rail filler to receive the lumber or slabs forming the is. do surface.
I also provide for use it desi is not essential, a rail pad 8 whic' cvreiierably is arranged between the rail 1 ties The rail 1, rail filler 3, 3 and the rail used, all being in position if then place against the rail filler a lumber st. 9
xedly secure same in place by teaching it to at least every other tie El. sgringer 9 is of the height from the tie E2 to its top such that its top surface is in line with the shoulder 5 on the rail filler3. Next to the stringer 9, but slightly spaced therefrom, is la1d a second stringer 10, and next to that, but spaced therefrom is laid another stringer 10, the number of stringers used depending upon the pavement to be provided. In a tracli crossing the space between the rails would control the numberlaid between the rails and on the outside of the track either the length of the ties or the amount of approach that is to be provided controls. Each-of the stringers 9 and 10, especiallybetween rails must be of the same vertical height from the ties 2, 2 so as to afford a level foundation for the surface slabs. These strin ers 9, 10 laid longitudinally of the track are fixedly secured preferably to at least every other tie 2. Upon the shoulder 5 of the rail filler 3, the upper surfaceof the stringer 9, anda portion of the upper surface of the next adjacent stringer 10spanning the space between tringers 9 and 10 is laid longitudinally of t e track a surface or trailic bearing slab 6, which is spiked, lag screwed, or otherwise fixedly secured, to the stringers 9 and 10 or both.
For convenience in obtaining'accessto. rail or rail filler I prefer to attach it to stringer 9 only. Arranged at an angle to said traliic bearing slag "6 are trafiic bearing slabs 7, '3. These slabs 7, 7, completely cover the remaining foundation stringers bridging spaces between and providing a traffic bearing surface. These slabs 7, 7 are likewise spiked, lag screwed, or otherwise permanently secured to the foundation stringers l0, 10. Between the ends of the slabs 7, *2" and the slab 6, it provide suitable means 11 to seal or close against moisture. As shown 11 is a body of preformed plastic v bituminous material that is suihciently plastic to be readily compressed into any inequalities and se l. the joint between the slabs and also serve s an expansion joint. As will be seen drawing and the above I have rorack pavement or crossing which is ltially a unit structure, all parts of ire preformed, readily laid, and affords easy cess to any part for purpose of repair lacen'ient without disturbing the entire crossing or adjacent roadway. .ln carrying out my invention, ll prefer to use in the manufacture of my traclrpaven1ent,rail tiller, and surface or tratic bearing slabs, a material that will not cree flow, fracture, or dust, is capable of ro onged use without loss of volume and will not check or warp but is waterproof, is sufficiently lastic to absorb with n itself the shocks, an vibrations to which 1t must be submitted without transmitting same to adjacent structures, and without becoming deformed under same or under the strains and pressures of all ordinary passing traffic. I
ave found such a material in a combination of asphalt, which affords bonding, waterproofing withlife rolonging qualities, and a filler composed of a mixture of fibers and mineral particles either powdered or granular. This combination of asphalt and a filler, the major portion of the combination being the filler, is preformed to form the rail fillers 3, the slabs 6 and 7 under high pressure. Such a material has all the required qualities set forth about to absorb and dissipate within itself the shock, strains and vibrations to which it is submitted by rail traflic, or the vehicular trafiic, without loss of volume, or damage to the pavement or to achacent road structure while withstanding without deterioration the effects of natural elements to which it is subjected in all ordinary use.
In the construction of the slabs 6 and 7 a larger quantity of mineral filler is preferably used and they are moulded under greater pressure than the rail filler to form a greater degree of hardness.
In Figure 3, I have shown a modification in which I omit the longitudinal surface slab 6 and a ply the lateral slabs 7 so as to extend over t e rail filler shoulder.
After the track avement has been constructed as describe I may a ply to the surface and in the crevices a suita le surfacing of hot asphalt or asphalt and sand.
The construction on the outside of the raiis may be the same as between the rails or if de- I sired the lateral surface slabs 7 may be omitted and only longitudinal slabs 6 used.
I preferably form the surface slabs 7 so that the abutting edges are complementary to each other and a portion of one overlaps a ortion of the adjacent slab as shown at 7 in .lg. 2.
The expansion joint 11 maybe of any desired form either of the preformed type or of the cured type.
