Improvements in Making Macadam Roads.
GEORGE FREDERICK FRY 4 Devonshire Road Greenwich London, Contractor
do hereby declare the nature of this invention to be as follows:-
The object of this Patent is to do away with the dirt working up out of the
road, and by that means causing the road to last longer, keep cleaner & set
harder.
The principal in this is to use lime or cement or any other material of the nature
of lime or cement mixed with another material or used by themselves the other
material may be sand or fine granite or any other material of the nature of sand or
fine granite. The material when mixed is to be used for making grout for grouting
in macadamized roads that is to say roads formed of broken granite, flints, broken
rag, or any such material as is now used for roads that vehicle traffic pass over and
known by the name of macadam roads. The road or roads are to be made in the
same way as they are now but instead of using the material they now use for
grouting or slopping the roads in with during the progress of making with steam or
other roller or rollers, this material will be used in such ways as I may direct.

COMPLETE SPECIFICATION.
Improvements in Making Macadam Roads.
I GEORGE FREDERICK FRY of 4 Devonshire Road Greenwich in the County of
Kent Contractor do hereby declare the nature of this invention and in what manner
the same is to be performed, to be particularly described and ascertained in and by
the following statement :-
The object of my invention is to prevent sand, mud or other material working up
between the pieces of the road metal on to the surface of the road thereby causing
(a) dislocation of the particles of metal (6) mud on the surface of the road
(c) increased resistance to traffic passing over the road and (d) uneveness and
ultimately the breaking up of the macadamized surface.
To effect this object I proceed as follows, with roads used for vehicular traffic
the surface of which is made of granite. ragstone, flints, or other similar material
broken into small pieces commonly called road metal, the surface of the road is first
suitably prepared and then a layer of road metal of the thickness required is
spread over in the usual manner so as to present a surface of the form and section
that may be required in each case. The consolidation of the road metal so spread
is then commenced by any suitable contrivance preferably a steam roller or other
roller or rollers. When the surface has been so far reduced as to be fit to receive
some grouting material I apply a suitable fine grouting preferably made of lime or
cement or any other material of the nature of lime or cement mixed with another
material or used by themselves the other material may be sand or fine granite or
any other material of the nature of sand or fine granite, but which may be made of
any suitable material which will produce when dry a good hard set surface.
I pour
the grouting on the surface of the metal and distribute it as evenly as possible
thereon by brooms or other suitable contrivance and at the same time continue the
consolidation of the metal by means of the steam roller or other rollers or
contrivance until the surface is rendered sufficiently solid and the grouting has
thoroughly penetrated into the road making materials over the whole expanse of the
[Price 8d.]

page_text: metal. The road surface after completion in the manner above described must not be
used for traffic until a sufficient time has elapsed for the grouting to set otherwise the
grouting will be liable to immediate pulverization by traffic, and the object in view
will not be attained. It is important that the road inetal should be kept as wet as
possible during consolidation before the grouting is applied to it. Should the
grouting be composed of any quick setting material care must be taken to apply it
in such a way that the consolidation of the metal is completed before the grouting
commences to set.
Having now particularly described and ascertained the nature of my said inven
tion und in what manner the same is to be performed, I declare that what I
claim is
In the making or repairing of macamadized roads the use of grouting made of
lime or cement or any other material of the nature of lime or cement mixed with
another material or used by themselves the other material may be sand or fine
granite or any other material of the nature of sand or fine granite or other suitable
material mixed with water and applied with the road metal during the progress of
consolidation substantially as and for the purpose set forth and described.
Dated this 13th day of April 1893.
