The work of repair should begin as soon as defects appear, for, if
neglected, after every rain the depressions make little pools of water
and hold it like a basin. In every case this water softens the material,
and the wagon tires and horseshoes churn up the bottoms of the basins.
This is the beginning of the work of destruction. If allowed to go on,
the road becomes rough, and the wear and tear of the horses and wagons
are increased. Stone roads out of repair, like any common road in
similar condition, will be found expensive to those who use and maintain
them. The way to do is to look over a road after a rain, when the
depressions and basins will show themselves. Whenever one is large
enough to receive a shovelful of broken stone, scrape out the soft dirt
and let it form a ring around the depression. Fill with broken stone to
about an inch or two above the surface of the road. The ring of dirt
around will keep the stone above the surface in place, and the passing
wheels will work it on the broken stone and also act as a binder. The
whole will work down and become compact and even with the road surface.
The ruts are treated in the same way. Use one and one-half inch stone
for this; smaller stones will soon grind up and the hole appear again.
The second cause of the necessity for road repairs is want of water.
This occurs in summer during hot, dry spells. The surface stone
"unravels;" that is, becomes loose where the horses travel. This
condition is more liable to be found on dry, sandy soils, and where the
roadbed is subject to the direct rays of the sun, and where the winds
sweep off all the binding material from the surface. In clay soil there
is little or no trouble from "unraveling." The cause being found, the
remedy is applied in this way: Put on water with the sprinkler before
all the binding material is blown off. If the hot, dry weather
continues, sprinkling should continue. Do this in the evening or late in
the afternoon.
The next mode is to repair the road by placing the material back as it
was originally. The loose stones are placed in the depressions and good
binding material--garden loam or fine clay--is put on, then roll the
whole repeatedly and dampen by sprinkling as needed until the whole
surface becomes smooth and hard. Care must be taken that too much
binding material is not used. If too much is used it will injure the
road in winter when there is an excess of water.
