Remarks on the Present System of Road Making: With Observations, Deduced from Practice and Experience, With a View to a Revision of the Existing Laws, and the Introduction of Improvement in the Method of Making, Repairing, and Preserving Roads, and Defending the Road Funds from Misapplication.

Macadam roads; Roads -- Great Britain
The only proper method of breaking stones, both for effect and economy,
is by persons _sitting_; the stones are to be placed in small heaps, and
women, boys, or old men past hard labour, must sit down with small
hammers and break them, so as none shall exceed six ounces in weight.
_The Tools to be used are,—_
Strong picks, but short from the handle to the point, for lifting the
road.
Small hammers of about one pound weight in the head, the face the size
of a new shilling, well steeled, with a short handle.
Rakes with wooden heads, ten inches in length, and iron teeth about two
and a half inches in length, very strong for raking out the large stones
when the road is broken up, and for keeping the road smooth after being
relaid, and while it is consolidating.
Very light broad-mouthed shovels, to spread the broken stone and to form
the road.
Every road is to be made of broken stone without mixture of earth, clay,
chalk, or any other matter that will imbibe water, and be affected with
frost; nothing is to be laid on the clean stone on pretence of
_binding_; broken stone will combine by its own angles into a smooth
solid surface that cannot be affected by vicissitudes of weather, or
displaced by the action of wheels, which will pass over it without a
jolt, and consequently without injury.
PRICES.
The price of lifting a rough road, breaking the stones, forming the
road, smoothing the surface, cleaning out the watercourses, and
replacing the stone, leaving the road in a finished state, has been
found in practice to be from one penny to two-pence per superficial
yard, lifted four inches deep; the variation of price depends on the
greater or lesser quantity of stone to be broken.
At two-pence per yard, a road of six yards wide will cost, therefore,
one shilling per running yard, or 88l. per mile.
Any rough road may be rendered smooth and solid at this price, unless it
be weak and require an addition of stone, or require some very material
alteration of shape.
Breaking stone has been reduced in price by the use of more proper
hammers, and the sitting posture.
The Commissioners at Bristol used to pay fifteen pence per ton for
limestone from Durdham Down, for the use of their roads, and broken to a
size above twenty ounces.—Stone is now procured from the same place,
broken so as none exceed six ounces for ten-pence per ton! and the
workmen are very desirous of contracts at that rate, because the heavy
work is done by the men, the light work with small hammers by the wives
and children, so that whole families are employed.
In Sussex, the proportion is greater between former and present prices;
the breaking of flint cost at one time two shillings per ton, and is now
done, by introducing a better method and fitter tools at one shilling
per ton.
