PAVEMENT.

Specification of Letters Patent.

Patented Sept. 8, 1914.

' Application filed October 24, 1912. Serial No. 727,555.

T 0 all whom it may concern:

Be it known that I, VICTOR L. PHILLIPS, a citizen of the United States, Kansas City, in the county of Jackson and State of Missouri, have invented certain new and useful Improvements in Pavements. of which the following is a specification..

This invention relates to pavements and more. especially to pavements composed of a plurality of layers of which the upper layer is of bituminous material, and my primary objectv is to produce what may be termed a bituminous pavement, provided with a metal reinforcement whereby creepage, buckling, checking, cracking and chipping of the bituminous material is prevented, and a further object is to provide means for anchoring the pavement to the glittering or curbing in a simple and efiicient manner, whereby the pavement is prevented from receding from the glittering or curbing, through contraction or other cause.-

WVith' these general objects in View, the invention consists in certain novel and peculiar features of construction and organization as hereinafter described and claimed; and in order that it may be fully understood reference is to be had to the accompanying-drawing, in which- Figure 1, is a sectional perspective View of a pavement embodying my invention, and composed of a concrete base and a bituminous top. Fig. 2, is arsimilar View of a paving differing from Fig. 1, chiefly in making both the base and the top of bituminous material.

Referring to the drawing in detail, 1 indicates the curb and 2 the guttering. In Fig. 1, 3 indicates a concrete the earth between the gutterings 2, and provided with a roughened upper side 4:. 5 are tie rods arranged transversely and shown-as embedded in the gutterings and in the concrete base 3, and to make the bond between the base and gutterings more effectual, the rods 5 are provided with hook terminals 6, which must be broken before receding of the base from the guttering can occur. 7 is a foraminous reinforcement. preferably in the form of woven wire or expanded metal laid upon the base for its full width and length, and 8 is the top or bituminous layer of the pavement, the upper side of the same being flush with the corresponding faces of the guttering, this top layer being adapted residing at base laid upon to be ta-mped or rolled so that it shall not only provide a hard and smoothfinished surface but will also extend through the interstices of the foraminous metal reinforcement and therefore rest solidly upon the roughened upper surface of the concrete base, it being obvious mg the bituminousicoating or layer upon the concrete base, the foraminous metal renforcement becomes thoroughlyembedded 1n such bituminous layer or coating.

In Fig. 2, a base 9 of bituminous material isfirst tamped or rolled upon the earth between the gutterings, and then said base is anchored in position by stretching across it at suitable intervals the tie rods or anchors 10; the same extending into the gutterings and terminating in hook ends 11, which perform the same function as the hook ends 6 of rods 5. The rods 10 are also preferably provided with upwardly projecting spurs 12, to take into the interstices of the foraminous metal reinforcements 13, corresponding to'reinforcement 7, covering the base 9 fromend to end and side to side, these spurs thus serving to guard against. edgewise movement of the reinforcement, and then a top layer or coating of bituminous material r14, corresponding to layer or coating 8, is deposited upon the reinforcement 15, and is tamped or rolled until its upper surface is flush with the corresponding surface, of the guttering, the curbing and guttering in both figures being correspondingly numbered.

The special composition of the bituminous material is not important and the number of layers of the same and of the reinforcement may be varied without departing from the principle of construction involved. Preferably the bituminous material will be composed of bitumen, sand, rock or gravel, and Portland cement or stone dust, or of a composition of bitumen and one or more of the other elements named, and it is also to be understood that a concrete or equivalent base may be employed or not as preferred.

From the above description it will be apparent that I have produced a bituminous pavement, embodying the features of, ad vantage enumerated as desirable, and which obviously can be laid economically and possesses the desirable qualities of strength, durability and cheapness and which therefore is suitable for streets subjected to that by thus compressplurality of layers of heavy tr'afic as well as for residential streets where the traflic is light.

I claim:

1. A pavement, comprising curbings, a paving material spread from curbing to curbing, a foraminous metal reinforcement interposed between a pair of the layers, and a series of rods inter posed between said pair of the layers and engaging the said reinforcement and provided with hooks embedded in the said curbings.

2. A pavement, comprisinga plurality of layers of paving material, the bottom layer having a roughened upper surface, a foraminous metal reinforcement resting upon the roughened layer and embedded in the top layer, and rods extending transversely between the layers and under the reinforcement and provided with upwardly project-' ing spurs engaging interstices of such reinforcement.

3. A pavement, comprising a curbing, a plurality of layers of paving material ad-- jacent the curbing, a foraminous metal reinforcement interposed between a pair of adjacent layers, and a series of transverse rods interposed between a pair of the layers and each provided with hooks embedded respectively in said curbing and paving material, certain of said hooks being also engaged with the interstices of such reinforcement.

4. A pavement comprising a plurality of layers of paving material, a curbing bordering each side of said layers of material, a foraminous metal reinforcement interposed between a pair of adjacent layers of said material, and. a series of transverse rods extending between said curbs and provided with terminal hooks embedded therein and also with a plurality of spurs embedded in said paving material and engaged with the interstices of said reinforcement.

In testimony whereof I afiix my signature in the presence of two witnesses.

vioron L. PHILLIPS.
