Referring in detail to the construction of my` invention as a means of resurfacing and widening road structures, lj provide in connection with the road bed tof integrally massed hard materials side plates 2 and 3 shown in Fig. l, as side supports for extended portion of a road resurfacing material where it is desired to widen the road while resurfacing the same.

The side plate-s 2 and :i are provided with integral upturned outer flanges t and 5 for holding the resurfacing materials substantially in place, while the lower and inner flanges i5 and'l of the plates and 3 are adapted to flank and engage `the outer vertical edges of the road bed i, which affords a continuous massive foundation for the new surface. It are connected by suitably spaced tierods`8 which `extend across the road bed i to establish a tensile connection between these two plates.

The tie rods t may bessubstantially secured to the Aplates E and 3 either by riveting, welding, r

9. This cushioning course `Ei serves the twofold The inner edges of the plates 2 and purpose of providing a leveling agent for leveling i up the inequalities of the pavement and providing a proper foundation for the brick course on top.

. The plates 2 and 3 may be provided with transf It will be noted that the side plates I2 and I3 in Fig. 2 are similar to the plates 2 and 3 shown in Fig. 1, excepting the reinforcing bracket or angle braces I4 and I5 for providing a compression bearing for supporting the plates i2 and i3 against the sides of the road bed I. These plates are preferably connected substantially together across the road bed i by tie rods 8 similar to the arrangement shown in Fig. 1.

It will be observed thatin the eventl of Aoutward strains or stresses upon the saddling or side plates of my invention they will be amply supported through the tensile strengthof the .tie rods 3. For instance, the tie rods 8 as observed in Fig. l carry a tensile strain when road stresses and strains are exerted against `the plates 2 and 3. The tie rods 8 cannot give Y Inaterially' Lin `their support of these stresses and they are aided by the inward gripping or clamping action of Yflanges 6 and I against the massive side walls of the road bed I. rIhis arrangementprovides a very strong cantilever construction onthe principle of a third class Vleverage wherein therods provide the tensile fpower; the outward and downward stress 0n the plates 2 and 3 the weight; and;.the flanges G and 'I the fulcrum.

The side plates in Fig. 3 are similar to those shown in Fig. 1 with the exception that these plates extend beyond the upturned curb or iiange with the idea of securing additional support from a wider range coverage of sub-grade along the road shoulder. These flanges are numbered i6 and I'I in the drawing.

Where it is desirable to widen a road structure and where it is necessary to resurface the original structure, Fig. 4 illustrates a method of providing metallic supporting side plates it and I9. These side plates I8 and i9 are depressed so that the top of the upturned flanges 2G and El are level with the surface 2t of the original road structure. The top portion of these plates resemble a chan nel and the spaces between the flanges Sii and 22 and 2I and 23 are lled with some suitable surface material such as bricks 25 and asphaltic or bituminous mixtures It will be noted that in this manner the surface of the widened portionl of the road Vwill then be level with the surface 24 or the original road structure, thus providing a level trafic surface over the entire expanse of completed road. It will also be noted in Fig. e that tie rods are employed to join together the two outside plates iS and I9, while they are further braced on the bottom side respectively by braces or brackets 2l' and 2S which have an inward gripping or clamping action against the sides of the original road structure. The principle of support used here is the same as explained above in connection with Fig. 1.

There are many thousands of miles of roads originally built of concrete and other materials which have begun to crack and disintegrate to such an extent that it is necessary to resurface them in order to save them or prolong their life. When materials such as paving brick, blocks, bituminous or asphaltic mixtures are used, itis necessary to have a retaining wall or curb to hold such surfacing material in place. It is frequently found desirable to widen these old road structures. In such an event it is necessary to provide an `adequate foundation or base for such surfacing material. My invention adequately meets both of these needs by means of a rplurality of forms of steel plates which function as follows:

The plates are placed along both outer edges of the road with one edge of the plate resting on the edge of the old road structure. The plates then extend on a plane outwardly and away from the edge of the road for the desired distance and have an upturned flange which acts as a retaining curb for the surfacing material. On the bottom side of the plates and extending down adjacent to and in contact with the outer edge of the old road structure are turned down flanges 6 and l. The plates on opposite sides of the road are then firmly joined together across the existing road bed by means of spaced tie rods 8 so that there can be no tendency for the plates to spread.

This construction also takes advantage of the tensile strength provided by the tie rods 8 acting against the gripping or clamping action upon the sides of the road structure by the above mentioned downturned flanges, so that in the event of excessive weight occurring on the outer edge of the said plates it would be immediately checked by the above mentioned forces. Additional rigidity may be given to these plates to prevent bending or sagging by means of brackets at spaced intervals, as shown in the accompanying drawmg.

After having placed these plates, tie rods and braces'in place it is a very simple matter to cover the whole road widening and resurfacing support structure with a satisfactory surfacing ma terial which will add many years to the life of the old road structure. The manner of using the metallic plates permits much easier installation and it is cheaper than constructing this extra width base and curb of concrete or other similar material, and eliminates the necessity of tying the road up for traffic while the concrete is curing.

In the event it is desired to simply widen Ia road (see Figs. -i and 6) and not resurface the old part, my invention provides for the plates vto be formed so that they will be depressed on either side of the old road structure in such a manner that when the plates are surfaced with a suitable surfacing course, they will present an even and level wearing surface hush with the original pavement. In this event it will be found necessary to have these plate units hrmly joined together by at or round tie rods across the top of the old pavement, and it may b e desirable to rabbet a slot or groove across the old pavement in which these tie rods would rest so that it would not form a ridge or raised place in the old road portion. This method is clearly set forth in the accompanying drawing in the iigures above mentioned.

Where it is desired to provide side plates for a new road structure as a means of strengthening the road support and holding the same with a substantial inward grip along the sides of the base to prevent kthe shoulders of the road bed from more easily cracking, chipping and otherwise distintegrating under stresses and strains of traiic over weakened or uneven sub-grades, `the side plates 29 shown in Fig. ll will amply meet such a need, and is held in place by tie rods 3B and 3| embedded in the pavement i as they extend across through the road bed to connect opposite side platesl at a point intermediate their outer top edges and their inner and lower edges.

It will be noted that the basic idea of the present Vinvention resides in the provision of shelf-like structures which in turn derive their main support from the foundations of the old road structure. This method of widening a road obviates the necessity of providing anew vfoundation structure for the road extension and at the same time firmly and ruggedly co-ordinates the new surface structure with the old foundation. 'Ihis results in a new road surfacewhich is supported in part directly upon the old foundations and in part upon the shelf-like extension plates, although the new surfacing gives the appearance of a completely new road throughout.

The invention is one which utilizes to the fullest extent the value of the original road foundations, which though they may be impaired `on the surface are nevertheless suficiently massive and rugged to support the new and extended surfacing. This method of mending roads results in a great saving of materials` and time and expense, and at the same timeresults in a road of increased surface depth and of materially greater width than heretofore.

Numerous Variations in the method of utilizing the present invention are contemplated, depending more or less upon local conditions and the character of the original road which it is desired to resurface.
