Vitrifed brick makes the best ana
the cheapest pavement for streets ana
/ IN nix it is the prettiest. The streets
of Lynchburg, Va, were paved with
vitrifed brick about twenty years 9
the pavement is still in good con-
dition. The bed consisted or Wen
gravel, and asphalt was useo
between the brick.
Perhaps the hest clay for vltrlfeo
brick in the United States is FOUND
near Salem. Va. !.
] detail some Of the advantages o.
brick pavements:
Ease Of traction.
Good foothold for horses.
Comparatively noiseless.
Yields neither dust nor mud.
Adapted to all grades.
Easily repaired.
Easily cleaned
Put slightly absorbent.
Pleasing to the eye
Expeditiously laid.
Durable under all kinds OF traf-
hc.
The principal defects of brick pave
ments arise from lack Of uniformity
the atty Of the bricks, and from
the liability of incorporating in tn
pavement bricks Of too soft or porous
a structure, which are apt to crumble
and disintegrate under the action OF
traffic and frost.
The smoother the surface Of pave
ments the lighter the grade should
be.
Resistance to traction in the diff
ferent kinds Of pavements has been
found to be approximately, as fol-
lows:
Asphalt. 80 to 10 pounds per ton.
IQriox & RI Al 01rrHc 90 ton
stone block. 80 to so pounds per
Wood block. 80 to so pounds per
ton.
Some OF the advantages OF asphalt
pavement are:
Ease Of traction.
Comparatively noiseless.
IT is imnervious to water.
It is easily cleansed.
It produces neither muir nor dust.
IT Is pleasing to the eve.
It suits all kinds Of traffic.
There is neither VIBRATION nor con-
cussion in travelling ove it.
1t is expeditiously laid. thereby
causing little inconvenience to traffic.
Openings to gain access to under
ground pipes arc easily made.
IT is durable.
It Is easily repaired.
n defects Of asphalt pavement
are: It is slippery under certain at
mospherfc conditions. The American
asphalts are much less SO than the
European on account of the grannlar
texture derived from the sand and
perhaps too because Of climatic Diff
ferences. The difference is really very
noticeable. The European sphalts
are as smooth as glass, while he
n"er'can somewhat resembles sand
