2 Claims. (Cl. 94-4) This invention relates to the class of roads and pavements and more particularly to a novel highway construction.

The primary object of the present invention resides in the provision of a highway construction having means to absorb shock from rolling loads and impacts thereby affording a surface having considerable tendency to resist breaks or cracks.

A further object of the invention resides in the provision of a highway construction having a surface formed of a material that will aid in-traction and which is -constructed in a manner so as to permit long life, easy maintenance and efficient drainage.

An additional object of the invention resides in the provision of a highway construction capable of being constructed entirely by modern high capacity machinery so as to eliminate most manual labor and in which large portions of the highway can be substantially prefabricated.

A yet further object of the invention resides in the provision of a highway in which conduits are formed in the steel sections thereof for reception of electric cables, pipes and the like eliminating overhead and unsightly utility connections heretofore utilized.

Still further objects and features of this invention reside in the provision of a highway construction which may be substantially corrosion resistant, capable of having a resilient top made in long rolls and applied mechanically and which is comparatively inexpensive to construct thereby permitting wide utilization on the highways of the nation. Y

These, together with the various ancillary objects and features of the invention which will become apparent as the following description proceeds, are attained by this highway construction, preferred embodiments of which have been illustrated in the accompanying drawings, by way of example only, wherein:

Figure 1 is a transverse sectional view of one form of a highwey constructed in accordance with the concepts of the present invention;

Figure 2 is a vertical sectional detail view as taken along the plane of line 2 2 of Figure l; and

Figure 3 is a partial sectional detail view of the modiiied form of the highway construction.

With continuing reference to the accompanying drawings wherein like reference numerals designate similar parts throughout the various views, reference numeral is used to generally designate one form of highway constructed in accordance with the concepts of the present invention.

This highway 10 includes a pair of curb walls 12 and 14 having footing portions 16 and 18 of enlarged constructions so as to form the curb walls 12 and 14 in generally an inverted T-shape.

Supported by the footings 16 and 18 of the curb walls and extending therebetween is a drainage base 20 which may include drain tiles or the like and which may be constructed out of cementitiously bonded stone or slag, or the like. Positioned on top of the drainage base 20 is a base plate 22 formed of steel which may be coated both on the top and bottom surfaces with a suitable asphalt emulsion or other corrosion inhibiting coating.

Welded to the plate 22 and rising therefrom are a plurality of suitably spaced channels such as are indicated at 24, 26 and 28. To the channels 24, 26 and 28 and the other channels there is welded an upper plate 30, the channels holding the upper plate 30 in spaced relationship relative to the lower plate 22. The channels 24, 26, 28 etc., as well as the upper plate 30 may be suitably coated with an asphalt solution or other corrosion resistant coating. The plates 30 and 22 may be made integral in considerable lengths and the individual lengths of the plates may be connected by suitable expansion joints or the like, not shown.

Positioned on the upper plate 30 is a strip 32 of suitable material, such as rubber, having cords 34 embedded therein for reinforcement. This strip 32 may be bonded to the upper plate 30 in any convenient manner by an adhesive solution or the like or may be otherwise afiixed into place. The strip 32 extends between the curb walls 12 and 14 and the upper surfaces 36 thereof lies ush with the upper surfaces 38 and 40 of the curb walls 12 and 14.

It is to be recognized that between the various channels 24, 26, 28 etc. and the upper and lower plates 30 and 22, respectively, there are formed suitable conduits for cables, telephone wires, electric wires, and the like, as well as, water and gas pipes and such other utilities as desired.

In Figure 3 there is shown a modified form of the invention in which the base plate 50 rests on the drain base 52, the base plate 50 being provided with depressions as at 54 and 56 for reception of the channels 58 and 60 which are welded thereto, the depressions 54 and 56 serving to interlock the plate 50 with the base 52 and to interlock the Ichannels S8, 60,' etc. with the base plate 50. The channels 58, 60 etc. as well as the base plate 50 may be suitably coated with a corrosion resistant coating of any suitable material. Positioned on the channels 5S, 60 etc. is an upper plate 62 having upwardly offset portions 64 and 66 for reception of the channels 58 and 60. These upwardly oifset portions serve to form alignment means for the plate 62 and further form an interlock for the wearing strip 68 posivtioned thereon, the wearing strip being otherwise similar in construction to the wearing strip 32 when having cutout portions for reception of the upwardly offset portions 64 and 66 as may be desired.

The foregoing is considered as illustrative only of the principles of the invention. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation shown and described, and accordingly all suitable modifications and equivalents may be resorted to, falling within the scope of the appended claims.

What is claimed as new is as follows: v

1. A highway construction comprising a pair of spaced elongated curb walls, a drainage base extending between said curb walls, an imperforate metallic base plate overlying and resting on said drainage base, metallic channel members welded to said base plate and rising therefrom in spaced parallel relationship, an upper plate disposed on and welded to said channel members, and a resilient wearing strip on said upper plate between said curb walls, said base plate having spaced depressions therein projecting into and interlocking with said drainage base, said top plate having upwardly offset portions projecting into and interlocking with said wearing strip, said depressions and olset portions being in vertical registry and said 'channels being received in the recesses formed by said depressions'and offset portions.

2. A highway construction comprising a pair of spaced elongated curb walls, a drainage base extending between saidlcurb walls, an imperforate metallic base plate overlying'and resting on said drainage base, metallic channel members Welded to said base plate and rising therefrom in spaced parallel relationship, an vupper plate disposed on and welded to said `channel members, and a resilient wearing strip on said upper plate between said curb walls, said base plate having spaced depressions therein projecting into and interlocking with said drainage base, said'top -plate having upwardly oiset portions projecting into and interlocking with said wearingstrip, said depressions and oiset portions being in vertical registry and said channels being received in the recesses formed by said depressions and offset portions, the upper surface of said wearing strip lying flush with said curb walls.
