Stanley, Parkesburg, Pa. Application April 22, 1937, Serial No. 138,408 2 Claims. (Cl. 94-—4) My invention relates to road building and more particularly to improvements in road beds for highway roads. The principal object of my invention is to pro 5 vide a road structure and road bed therefor rendering the road structure waterproof at the bottom and sides thereof and adapted to de?ect water rising underneath the road bed, or settling thereunder, to the sides of the ‘structure for drainage through the usual ditches at the sides of the road. - - Another object is to provide a road structure which may be easily and economically built, is impervious to water at the top, bottom and sides 15 thereof and which will not crack or buckle under the action of frost. To the accomplishment of the above, and sub-4 ordinate objects presently appearing, a preferred embodiment of my invention has been illustrated 20 in the accompanying drawing, set forth in detail in the following description, and de?ned in the claims appended hereto. In the said drawing: Figure 1 is a View in transverse section of a road structure embodying my improvements, and Figure 2 is a fragmentary detail view in trans is utilized. The bottom layer 8 is sunk into the layer 7 of earth and formed with beveled side edges II spaced from the bottom 3 of the guard I parallel therewith for freedom for expansion under different temperatures. The intermediate layer 9 and the top layer It extend. to the side flanges 2. The top surface of the upper layer I0 is crowned in the usual manner and tapers to the side ?anges 2 ?ush with the upper edges of the latter. As will now be seen, the described road struc ture is rendered impervious to the action of wa 10 ter at the bottom and sides thereof by the guard I and similarly protected at its top by the ma terial of ‘the top layer I0‘. Any water accumulat- 15 ing under the structure, as from springs is de ?ected, in rising to the surface, by the guard I, to the ditches 5. The invention will, it is believed, be understood from the foregoing description 20 therefore without further explanation. Manifestly the invention is susceptible of modi ?cation, as regards details described, without de parting from. the inventive concept and right is herein reserved to all such modi?cations falling within the scope of the claims appended hereto. What I claim is:— , 1. A road structure comprising a casing-like verse section. Describing my invention in detail, with refer ence to the drawing by numerals, in the illus trated embodiment thereof the road ‘structure of my invention comprises a casing-like base, or guard of galvanized metal including side ?anges and a bottom of obtuse angled shape in cross section, respectively, and adapted to be embedded bed, guard I of galvanized tin or other, suitable metal impervious to rust having opposed vertical in the ground, a layer of earth in said guard, and a laminated structure of cement and stone built up on said layer, the lowermost lamination being side ?anges 2 and a bottom 3 of inverted. cone shape in cross section. The guard I is sunk into spaced at its side edges from said ?anges, and the remaining laminations ?tting against the said 35 the ground represented at 4 with the upper edges of the ?anges 2 ?ush therewith. Ditches 5 are dug along side the ?anges 2. At the angles of the guard I‘the metal is joined together by elec 40 tric welding as indicated in Figure 2, at 6. With in the guard I is a bottom layer 1 of earth upon. which are built up bottom, intermediate and top layers or laminations, 8, 9 and Ill, respectively, of cement, or asphalt, and stone, the stone being us. UK graduated in size throughout successive layers. In the bottom layer 8 the stones are relatively large, in the intermediate layer 9 smaller, and in the top layer I? chipped stones, or stone dust, ?anges. ' ' 2. A road structure comprising a casing-like guard of galvanized metal including side ?anges and a bottom of obtuse angled shape in cross section, respectively, and adapted to be embedded in the ground, a layer of earth in said guard, and a laminated structure of cement and stone built up on said layer, the lowermost lamination being spaced at its side edges from said ?anges, and the remaining laminations ?tting against the said ?anges, and ditches extending along said side ?anges.
