toward the hill, and shed the water
into the upper ditch, from which It
should be permitted free exit through
culyerts under and through the en-
bankment to secure free run.off and
prevent concentration and consequent
erosion or washing out OF upper di.ch.
This Is usually secured by an OBJ
struction in the form of a dam across

The embankment or grade should
be constructed to secure free run-off
OF storm water and should have q
bern on either side of the roadway
proper. to support and sustain the
spread of the roadway under travel.
Sub-drainage should be appealed to
where It becomes necessary TO in
tercept q seep or drain sub-base, TO
lowering the water levels. Common
porous drain tile Is used exclusively
for this purpose by engineers; the
tile being laid in such manner as
TO drain into the lower di,ch where
the end should be protected by an
abutment.
Absolutely level gradients should
ever obtain in the construction of
embankment ON approximately level
ground, but slight grades should be
secured longitudinally TO secure run.
OF from the ruts produced by travel.
This can always be accomplished by
raising the grade Of the embankment
gradually from each side. when cul-
vert is constructed. SO that the cul.
vert will be- at the apex or summit
OF the grades.
This will prevent any holes near
the culvert and insure drainage of
the surface OF the roadway. Only sub.
soils should be used in the construc-
tion of embankment, and when com.
plete the slopes and surface should
receive cover of the surface soils.

prevent erosion of the slope by run.

construction of embankment by

The relation of drainage to good
road construction Is so important that
every little detail must be provided
for to insure the stability and perml
nency of the work The skill OF the
most expert engineer is often taxed
ana various experiments lnust he
made before success Is achieved, ana
