The roadway shall be graded so as
to strictly conform to the plans and
specifications for the road in ques-
ton, heretofore submitted to and ap-
proved by the State Highway Com.
missioner. The finished road shall
be not less than eighteen feet between
side bitches and have cross-section
oval in form with an average rise of
one inch to the foot from the edge
of the side ditch or gutter to the
center line of the road. The greatest
width recommended is twenty-four
feet between side bitches with cross
section similar in form to that de-
scribed for an eighteen-foot roadway.
The side bitches and cutters shall
have true grades and sufficient in
cline to furnish a free and uniform
flow of water to the nearest natural
outlets, which outlets must be so i'm
proved where necessary, as to carry
the water quickly away from the
highway. The inner slope of the
bitches shall be not sleeper than two
horizontal to one vertical and the
outer slope shall be not sleeper than
one and one-half horizontal to one YER
tical.
Tile drains shall be laid where
needed at such places and on such
grades as are shown on the plans.
After the road has been graded as
above described the gravel bed shall
be formed in the central part of the
road grade as follows Shoulders of
firm earth, or other suitable material,
will be placed on each side of the
gravel bed, not less than nine feet
apart, or such greater distance as
may be required to retain the width
of gravel specified. The shoulders
shall extend to the side bitches or
cutters at the same grade and curva-
ture as required for the finished road.
The shoulders may be formed by NOV
ing earth from the center of the pres
ent road grade to the sides, or by
browning the present road grade by
scraping earth from the sides toward
the center, or if sufficient suitable
material cannot be had along the
roadway, it shall be brought from
other places along the line of work.
After the shoulders and gravel bed
have been formed as above described
the whole roadway shall be rolled un-
til no more cbmpacting is possible.
The hollows developed by this rolling
will be filled with suitable material
under the direction of the officers in
charge, and the roadway again rolled,
and left in alsolid and firm condition,
everywhere parallel to the finished
roadway, thu gravel bed being eight
inches below the finished grade and
| parallel Thereto.
After the road has been graded and
/ in mo
a layer of gravel shall be spread on
| the prepared bed to such uniform
| thickness IS to be not less than five
inches dep after thorough rolling.
! The gravd for this course shall con-
sist of god clean bank gravel, not
less thar sixty per cent of which
shall be pebbles that will be retained
on screen Of one-eighth inch mesh,
and pass Through screen of two and
one-half inch mesh, and which shall
contain binding material in the form
Of clay or clay and iron, or pulver-
| led limstone, in amount not to exceed
forty per cent of the whole This
layer 4 gravel viii be sprinkled thor
oughly and rolled until no further
comparing is possible. Any holows
that my develop in this course of
gravel fduring the process of rolling
shall n filled with the same kind of
grave sand the rolling continued until
the sirface is uniform and hard and
everyghere parallel to, and three
inches below the surface of the fin
ishedtroad.
Tlegravel for the upper course shall
consist of good clean bank gravel, sixty
per emit of which shall be pebbles that
will be retained on a screen of one
eigHh inch mesh, and will pass
thrngh a screen Of one and one-half
