Let us. briefly consider the con
struction and materials used for
roads. No matter what materials are
used the quick removal of surface
and sub-soil water is essential The
proper grade determined by compe.
tent engineer assists in such removal.
The surface drainage Is secured by
proper grading and by giving the
pavement or road an arched surface.
The under drainage is provided by
laying either drain tile or sewer pipe
with wide open joints. Frequently the
soil is so porous as not to require
artificial under drainage. As a rule
all pavements require solid artif-
cial foundation. Its first cost is high
but once in place it will out last
many successive layers OF pavement
proper. The more firmly the wearing
surfaces are supported the longer
will they last.
The materials commonly employed
for roads are earth, broken stone for
macadam, brick, wood block, stone
block and asphalt. In the use of these
materials for street construction,
certain qualities have to be consider.

as the most important in most cities;
durability is important in heavily

illness are necessary in residential
streets; and safety is of importance

The earth and gravelled roads are
not really paved roads but they are
much used on country roads because

the most favorable conditions do not
usually attain high degree Of eff
cheney, and are not economical under
any considerable traffic.
Macadam roads as commonly con.
structed consist of two or more lay
ei's of broken stone, each layer be-
ing rolled to a firm bearing before
placing the next. The broken stone Is
usually placed directly upon the
earth road bed with due considera-
ton to proper drainage. Macadam is

Brick, wood block, and stone block
require foundation of crushed stone

the pavement depends very largely
upon the maintenance of a smooth
