macadam has been used quite extern

for light traffic, its life is very limit.

compelled within the next three years
to repaye~ 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 100000
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. -. .'~~. H.: "
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
is of value which will not
permit of the construction of a higher
type of pavement / would be of the
opinion that with your moist climate
and extremely heavy rains, that an as
plalt macadam would not give you a
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-
0emn the construction of macadam
road thereon. While a concrete base
with two-inch top may represent a
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.

crete whatever, merely four or five
inch asphalt concrete, so-called, or
pavement, and it has given
complete satisfaction. / think the
question of concrete is largely one
Of sub-grade. In some localities it is
essential that a wearing surface be
placed upon concrete base; in other
places, where sub-grade is good, con.
crete base is not necessary, but my
Idea of concrete road is that it
must be covered with some surface

automobile traffic or truck
