approximate prices range from Sl6j
to $3.50 per square yard. This class
of paving Is constructed of a j-inch
base of concrete with a 2i2.iuch top,
a 5inch base and Inch top finch
base and 2-inch top
Plain concrete pavement 6 INCHES
thick would cost approximately $145
to $3.50 per square yard.
Dolarway pavement concrete
base with a is.inch surface of pitch
and asphalt. would cost approximately
$3.50 per square yard.
From our findings. We recommend
the use OF bituminous concrete .
inches thick. laid on a concrete base
) inches thick, the btuminous con.
crete to be constructed of broken
stone, sand and asphalt both that and
the concrete base TO be constructed
in accordance with the specifications
issued by the organization of city of.
ticials for standardi2ing paving speci.
liCations and that Sioux Falls or Man
kato crushed rock be used in the btu.
minous concrete, and that Norfolk
gravel and sand be used in the con.
crete.
If this grade of paving is used we
recommend that a combination con
crete curb and gutter be used on eth.
or side Of the street, two feet wide,
the curb and Quilted to be laid "a
inches of concrete, q inch wearing
coat, resting on 1 inches of sand
This would make the finished sur
face of Norfolk avenue, where il is
proposed that the paving shall be 40
feet wide, consist of 6 inches of curb.
is inches of gutter on either side of
the street and 81 feet of bituminous
concrete through the center. on
North Ninth street, where it is pro.
| posed that the paving shall be 80 feet
wide, the gutter and curb would be
the same width and the center paving
would be 81 feet.
We advise against the use of con.
crete paving, for the reason that ex.
perience seems to have taught that
concrete cracks in spite of all precau
tions. the action of the frost heaves
the paving and this continues to wild
en- the cracks, the passing of vehicles
keeps chipping the edges and in a
very short time the cracks become
small bitches, and these it is impossi
Bile to repair. 1t is claimed that con

which gives off a fine dust that is
very disagreeable.
| We do not feel that the Dolarway
| pavement should be considered. foI
| the reason that the organization OF
city officials for standardi2ing paving
| specifications in New Orleans last
week refused to standardize this pave
ment, because it is such a new propo
sition that it has not been in use long
enough anywhere TO know as to its
lasting possibilities.
From our observation and informa
ton obtained we feel that perhaps the
best pavement for us. everything con
sidered, cost included, would be the
pavement known as Sarcolithic, which
is bituminous concrete on a cement
base.
This pavement has given excellent
satisfaction in South Omaha and a.
the stock yards of South Omaha, ant
seems TO your committee to be eS
| pecially adapted to our requirements
| There are other paVementS on the
market containing the same genera
characteristics as the Sarcolithic, bu
of their wearing strength We cannot
speak for lack of knowledge.
We recommend that during the con
struction of this pavement com
petent superintendent and paving
chemist be employed to inspect ant
test all material used and to super
| intend the work of construction.
We further recommend that the
company who secures contract to put
in this paving, be required to use {
l0,000-pound steam roller to finish il
with.
