necessary which may add as much as 15c
to the above during the life of the pave
ment. They may be relaid at the end of
that period at a cost of about So per
square yard.
"Sheet asphalt has been laid in Ore.
gon and Washington with generally sat
isfactory and good results. They are
unquestionably the most perfectly san
itary pavement and comparatively noise
less.
occasionally one fails by cracking
and disintegration at the surface where
traffic is too light and formerly under
heavy traffic they would become irreg-
ular and wave like in the surface, but
this fault has been largely overcome By
most modern methods of laying.
"The cost may be estimated at sa.75
per square yard, including maintenance
for ten years.
"The life may be estimated at 10
years when the surface may be relaid
at the cost of $l.90 to So per square yard.
"Bituminous macadam-This pave.
ment has been laid extensively through.
out the United States since 1900 anil is
reported upon from many quarters very
favorably and approved by the highest
authorities. It is practically macad-
am base with wearing surface of mae
adam bound with asphaltum and gives
a surface which may at will vary from
one similar to sheet asphalt to macadam.
Recently some of these pavements have
been laid on concrete base.
"This pavement is the rational one,
but there are elements which require
the greatest care and incest and most
constant inspection to prevent it being
failure. Several in the state are re-
ported as not satisfactory. The city
of Portland, however, has recently
| adopted it as its standard pavement.
ut has not been my good fortune to
this date to have an opportunity 10 in
spect this pavement either during the
laying or after completion and would
prefer to reserve any statement as final
until after such opportunity may ,re-
sent itself.
However, before deciding to adopt a
pavement for any street, it would seem
that this particular pavement would
merit close investigation.
eff in any case it would be adopted, I
would suggest, in view of the easy pos
sibility of making it failure and of it's
comparatively recent introduction, that
good and sufficient maintenance bond
be required.
Gone Objectionable feature is that the
process is patented.
"The cost may be estimated at $2.25
per square yard, with probable life of
from IL to Is years-when the surface
may be relaid at about $3.50 per square
yard.
"In this connection it would seem
profitable to consider the proper width
of roadway to pave.
"All the traffic that will ever prob
ably pass through residence streets may
be accommodated on a roadway of "a
feet, but for our 100 foot streets this
would see too meagre. A proper width
would be from SO to SO feet with wide
parking strips on either side. A street
in Athens, Pa, go feet wide has re-
Gently been paved for width of 80 feet
between curbs except for few blocks
which are 80 feet between curbs and
has proven satisfactory, notwithstand-
ing it is a fine residence district where
there is mucn driving and there is an
electric car line in the center of the
street.
"In the improvement of Naches avenue
two lS-foot roadways would seem suf.
ficient.
ut has been argued that parking
strips are not cared for and that buggies
are left standing at curb to obstruct a
narrow roadway. To the first I would
