CONCRETE ROADWAY.

Application filed August 21, 1922. Serial No. 583,1 26.

To all whom it may concern:

Be it known that I, JOHN HENRY PETERS, subject of the King of Great Britain and Ireland, residing at Bosebank Avenue, Darlinghurst, near Sydney, New South IVales, Australia, have invented certain new and useful Improvements in Concrete Roadways, of which the following is a specification.

This invention relates to concrete roads, and it has for one object to expedite and cheapen the work of road building and to procure maximum solidity and permanence in the road structure.

The accompanying drawing is a sectional perspective view of a concrete road in course of construction according to this invention.

According to the present invention, a roadway is constructed which includes a foundation or sub-grade upon which a roadway proper is placed. This roadway consists of blocks of stone, brick, or burnt clay which are preferably generally square or rectangular and spaced slightly apart from each other and formed into an essentially monolithic roadbed by pouring upon them concrete which fills the spaces between them and forms an inverted kerb along the sides of the road, and covers the tops of the stones or other blocks. Reinforcing of any suitable type may be put in place so as to be imbedded in the concrete.

A is a subsoil underbed which is made plane and solid by filling and by ramming and rolling. B are heavy blocks of stone which approximate to rectangular shape and have their length disposed vertically. It is very desirable that they should be ap proximately equal in length and placed in close order upon the underbed A. C are the interstitial spaces between the respective stone blocks, and M are vacant places equally spaced apart in checkerboard order. D is the concrete paving or topping which is laid over the stones B, and N is cement grouting in the interstitial spaces C. O are the inverted kerbs. The stones B, paving D, grouting N, and kerbs 0 form a monolith. H are fence; forms which contain the concrete during emplacement and form rails for the stricklers which are swept over the emplaced concrete to level and surface it; these fences are removed when the work is set. J are the road flanks which may be macadamized or gravelled. K are reinforcing bars embedded in the kerbs O, and L is reinforcing metal overlying the stones B. The reinforcement L when used in the construction is laid over the stones B before the concrete surfacing is placed on them.

In forming the road of my invention the ground is preferably graded, and it may be rammed or rolled. Upon the prepared subsurface, a single course of slabs, lumps or blocks of stone of generally rectangular shape is set. The stones are preferably rough hewn. Concrete is then poured over the stones, filling the spaces between them. Concrete is applied in suflicient quantity so as to form a layer over the tops of the stone. Preferably it should have a thickness of two to six inches, and in usual practice this will be about one-quarter of the total depth of the road. Reinforcing of expanded metal or any other type may be placed between the rows of stones or over them or both.

Although I have shown an operative in vention, still it will be obvious that many changes might be made in size, shape and arrangement of parts without departing materially from the spirit of my invention; and I wish, therefore, that my showing be taken as in a sense diagrammatic. Especially it will be obvious that the details of size and shape of the blocks, the details of the reinforcing used and means of application may be widely varied without departing from the spirit of my invention.

l/Vhat I claim as my invention and dcsire to secure by Letters Patent is 1. A concrete road containing heavy stone blocks on a sub-grade, spaced apart and with vacant spaces at uniform intervals and a paving of fine aggregate concrete on and between said blocks and filling said vacant spaces whereby said spaces filled with concrete form piers united to the structure.

2. A concrete road containing heavy stone blocks on a sub-grade, spaced apart and with vacant spaces at uniform intervals and a paving of fine aggregate concrete on and between said blocks and filling said vacant spaces whereby said spaces filled with concrete form piers united to the structure in combination with lateral extensions along the side of the stone bed which form inverted curbs united to the main concrete structure.

3. A concrete road containing heavy stone blocks on a sub-grade, spaced apart and with vacant spaces at uniform intervals and a paving of fine aggregate concrete on and between said blocks and filling said vacant spaces whereby said spaces filled with concrete form piers united to the structure in combination wlth lateral extensionsalong the side of the stone bed which form in:

verted curbs united to the main concrete structure, and metallic reinforcings positioned on top of the stones and imbedded Within the concrete.

In testimony whereof I aflix my signa' ture.

JOHN HENRY PETERS.
