SUGGESTION TO NEVADA on CONCRETE.

Commenting upon concrete paving at
s11S the Nevada Representative says:
1T will take very little computation,
however to convince the most casual
and skeptical observer that paving ac-
cording to this program is much
cheaper than wood blocks or bitullthic
paving at something like $2.25 a yard.
What is not apparent on the surface
is Just how much difference in real
merit or serviceability there may be
between the concrete pavement and
the higher priced pavements.
These things may not be apparent
on the surface but they gain remark
ably in radiance upon investigation.
For instance what is bitulithic? 1t is
a concrete pavement five inches thick
with a wearing surface two inches
thick composed of hard crushed stone
and sand mixed while hot with a BIZ
luminous asphalt or cement according
to a patented formula, rolled and
coated with some more bituminous
bitulithic cement and crushed rock
The patentees file with the city clerk
an offer TO all contractors that the
material for this wearing surface will
be furnished in place on the pave
ment for s145 per yard and then the
contractors proceed to bid on the ad-
ditional cost Of concrete pavement
underneath. The only question OF
merit is as to two inches OF sand ana
Portland cement concrete at s1.1s or
two inches of bituminous asphaltlc &C.
cent and crushed rock concrete at
s2.1s. Any city which has ever laid
both asphalt pavements of any kind
and concrete street crossing walks Will
furnish the object lesson for prefer
ence for the Portland cement concrete
wearing surface for durability. AT the
price OF 1913 paid for bitulithlc AZ
Grinnell the people who got concrete at
s11S could relay their concrete wear
ing surface two times. thus obtain
ing three pavements for the first price
of one. The facts are that in the best
tudsnlsnt OF experienced engineers the
one Portland cement concrete wearing
surface will outlast the bitulithic twice
over
Nevada men should go u l.eMars
and see a concrete pavement which has
lasted since 1904 ard cost them sl.2o
per ward TO lay when cement was al
most twice as high as the present price
A, Beuefontaine. Ohio. there Is con-
crete pavement eighteen years old and
unaffected by wear. 1t was made OF
cement. sand and gravel with the base
only four inches thick. Richmond. Ind"
has a cement pavement fifteen years
old and still in good condition. a pat
ented concrete pavement laid in chi
cago near the big Sears Roebuck es-
tabIishment is still in good condition
after six years Of Chicago traffic. More

Worcester. Mass, Lynn. Mass. ST.
Joseph. No. Portland. Ore. Troy ana

other large cities have concrete pave
.nents enduring their traffic for as
long as ten years.
And what is the life Of a brick
uaveuento Fourteen years VIII get
the most of them. The best OF prick
rayen7ents now costing 81 per yard or
better are concrete pavements five
inches thick with a paving brick wear
ing surface. Why pay $1,000 per city
block more for a wearing surface thae
does not make as beautiful a street and
probably will not last 50 long? What
is a wood block pavement? 1t is a
concrete pavement five inches thick
With a wearing surface Of wood blocks

wood decay Does anyone think that
= wood block will Withstand wheel
traffic longer than concrete? If so
why do we use concrete for street
crossings and warehouse approaches!
Why pay $3.50 per city block more for
