ROAD STRUCTURE
Elisha M. 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.
