BitumlnOus Macadam.

scribes the process Of laying the new
bituminous macadam pavement in
st. Louis;
"Under the Warren method OF pre-.
pairing and mailing granite bitumi-
uous paving the materials used are
crushed granite and coal bitumen.
The coal tar is prepared by patent
machinery, which eliminates injuries
or volatile oils, not by heat agitation,
which would effect the tar's cemen.
titiOus qualities, but by air agitation,
which rlds the material of useless
oils, while it retains the oils that
gives elasticity aud preserve the tar's
water proof qualities. The Granite
Bituminous Company, after the tar
is thus prepared by the Warren pro-
cess, mixes the bitumen with granite
crushed into small sizes and so graded
that when the combination is effected
1t is 90 to SO per cent solid, there
being only I or 8 per cent Of inter
stices 10 the mixture which are filled
by the addition of the bitumluous
cement The bItumen is added to
the granite in heated state, and
the two components, bitumen and
granite, are then put into revolving
mixer, which causes the stone to be
come coated with the bitumen anG
become a part Of it. When cemented
by the bitumen the produce has the
hardness Of stone, but it also has ad.
hesiveness and ductility, and is
water-p proof and noiseless, which
solid stone is not. Tar bitumen is
substance which is the most imper-
vious to water of any preparation
known, benos it a6sorbs no moisture
either from below or above.
"The process Of laying pavement as
followed by the Granite Bituminous
Company is first to grade the street,
then roll the sub.grade so graded
with heavy roller. Next six inches
of macadam are put down ard rolled
and then an inch and half OF finer
macadam is added, On the founda-
tion is laid two inches Of the granite
bituminous material and over that is
put dresser Of light cement, and the
final coat consists Of granite screen
ings one.half an inch In size thor
oughlY rolled into the surface, A
pavement SO constructed is 8 inches
from top to bottom and in every yard
Of wearing surface there are 25O
pounds Of granite. The result is a
practically ndestructible pavement,
nolseless, elastic and gritty, giving q
nonslippable foothold and being super.
ior through being waterproof and
more durable, to asphalt, macadam,
or any other material, 1t has all the
wearing qualities Of granite. Asphalt
is "a per cent sand, which has not
the structural strength of granite,
and only per cent Of bitumen. AS
a consequence moisture penetrates
asphalt and rots it very quickly,
Granite bituminous paving, though
more expensive to lay than asphalt il
put down at the same price, though
1t is laid In two-inch thickness, while
asphalt is laid only one inch thick. >
