PAVEMENT
IN THE FIELD
The "GOId Medal" Winner May
Be Laid in Greenwood.
ST. LOUIS HAS OVER MILLION
YARDS OF BlTUlITHIC.

Greenwood is to have the op
portunity of improving its streets
with the noted Bitulithic Pave
ment, otherwise known as the
Gold Medal Pavement, from the
fact that it was unanimously
awarded the gold medal at the St
Louis Worlds Fair in comparative
tests with all leading pavements
by one of the ablest board of en-
gineers ever assembled, perhaps,
in this country.
NOT AN EXPERIMENT.
Bitulithic paving is nothing
new. It is a modern, standard, up
to-date pavement that has been
adopted in over 120 cities in this
country. Over twenty million
yards have been laid in this coun-
try, something like 1900 miles, eq-
ual to a road bed thirty feet wide
stretching from here to New York
and beyond. Over one million
yards in St. Louis alone have been
laid.
This pavement may be said to
be the product of the brains, skill
and experience of noted civil and
mechanical engineers, chemists,
and practical road builders all un-
der the supervision and direction
Of the widely known firm of War
ren Brothers, Boston, Mass, who
rank among the greatest road
builders in this country. To Mr..
Fred C. Warren, however is due
The discovery of the basic principle
of this pavement which is that by
using several grades of stones so
graded that the stone aggregate
will OF itself have inherent stabili-
ty which relieves in a large meas
ure the burden and strain upon
the Bitumen binder. This factor
Of stability resulting from proper
Egrading the mineral ingredients
which is presumed to result from
friction, had never before been
aScertained. By thus combining
the mineral in pieces as large as
an inch and one-half in diameter
mingled with small pieces graded
down to dust, less Bitumen cement
was needed to act as a binder, be-
cause the mineral ingredients so
graded and mingled furnished
stability as well as density which
put the carrying strain upon the
mineral, the Bitumen cement being
used to fill all voids or air spaces,
and make a dense water proof
structure. This of course has
reference only to the Bitulithic
surface two inches in thickness
Which is laid on a concrete base
Of five or six inches.
10 the ambition of the Warren
Brothers to produce as near as
possible an ideal pavement, is due
the gradual development and i'm
provement of Bithulithic to its
present high state of perfection
after years of expenditure of great
sums of money.
The ideal pavement is smooth,
durable, noiseless, dustless, sani-
tary, slightly or attractive to the
eye. 1t is surprising how near
the Bitulithic comes to fulfilling
these requirements, and yet no at
tempt is made to claim that it is a
perfect pavement. Perfection is
not a thing of the world; the fin
est diamond has its speck, every
rose its thorn; nor can any human
work resist the decay of Time, as
drops OF water will wear away the
hardest stone. And so the Btu
llthlc pavement, like every thing
else, will under constant, heavy
traffic, wear and gradually yield
70 Natures relentless law, and
IKE iron and steel be resolved
pack into its original elements.
but while not everlasting there is
thls great merit about the Btu
iithic pavement, as stated, is found
ed on scientific principles, worked
out by skilled engineers, chemists
and road builders. No expense
mas been spared in perfecting it.
Every known material and combi-
nation OF materials proposed for
street paving have been investi-
gated and tested. Representa-
ives OF Warren Brothers have
virtually travelled the world over
seeking information, gathering
uata, and studying the paving
question in all the countries. And
