macadam, penetration method. To my
mind it is absolutely impossible to
build a road by this method which
will last during the life. of your ten
year bond. Oil macadam or asphaltic
macadam has been used quite exten-
siyely in the southern part of the
state of California, and also to very
large extent in the City of Oakland,
While this makes good. cheap road
for light traffic, its life is very limit.
ed and the city of Oakland will be
compelled within the next three years
tc TepaYe a great many miles OF
streets of this type of construction.
The county of Los Angeles was one
of the first counties in California to
bond itself for good roads, and ex.
pended the sum of $4,000, 900
in county highways several years ago.
Most of the highways constructed by
them were an oil or asphaltic maca-
dam of either the penetration or 9TH
er methods, they being the pioneers
in the county highway construction in
California. They naturally endeav-
ored to build the greatest number
of miles of road with their money,
rather than the best roads possible,
and understand that the mainten-
ance charge on some of these roads
is now exceeding per cent per an
rum. 1t is needless to say that they
will not construct any more of this
particular type.
Il am opposed to the construction
Of either asphalt or oil macadam
roads unless the same are to be paid
for in cash, and the construction is to
be upon residence streets where the
traffic is very limited, and abutting
property is of value which will not
permit of the construction of higher
type of pavement. would be of the
opinion that with your moist climate
and extremely heavy rains, that an as
phalt macadam would not give you
great deal of satisfaction. You also
state that the above streets are sub
ject to heavy automobile traffic and
more or less truck hauling. This, in
my opinion, should be reason to con-
iemn the construction of macadam
road thereon. While concrete base
with a two-inch top may represent
little greater outlay than you had an
ticipated for the initial cost, it will
more than reimburse you in the long
run, for have no hesitancy, in stat.
ing that if this type is made of war;
-enite or bitulithic pavement, it wilt
asst more than twice the length of
your bonds" ~. .-

If sub-grade. In some localities, it is
essential that wearing surface be
1laced upon a concrete base; in other
places, where sub-grade is good, con.
,rete base is, not necessary, but my
dea of a concrete road is that it
must be covered with some surface
which has more or less give to it-in
'ther words, it must have cushion on
t, particularly if it is to be used for
extensive automobile traffic or truck
lauling. A rigid pavement will not
stand up under this type of usage
without a cushion top
