Timely SUGGESTIONS
~ MR.. ANDERSON
On ROAD BUILDING

keep q macadamised road. To begin
with. a road. like everything else. must
have a good foundation or 1t cannot
be expected to stand the hard wear 1t
is subjected to. Some people run away
with the iion that to make road you
have only to lay down the macadam
the required depth and roll It; bat
there they make gross mistake.
In the ilrst place we will deal with
the making Of the road. and in the
second place. with the keeping Of 1t
after 1t has been made.
To make good road that will stand
heavy wear 1t is necessary first Of all
to make the foundation, which should
be No. macadam. the largest size
which comes out OF stone crusher,
lay that the required depth to put the
road into proper shape; that is to say
to make 1t with a nice round, not high
in the centre and running of to the
sides with fiat slope; but have It
rounded of evenly to the verge; such
a shape gives a good solid body to a
ioau' NUS anu : ihaSauah ehouiu
never on any account be mixed. as the
NO. l Is sure to come TO the surface
and spoil II.
When the foundation has been laid
1t should be blinded with little good
SOIL or, better still, road scrapings.
where the latter can be mad; II makes
admirable binding material; then ap-
ply the water cart freely before ron-
ing. This Is essential because II the
binding Is not suincaently wet II VIII
adhere to the roller, thus making the
macadam unsightly as well as spoil
ing IT Tor the next coating. which
should be NO. 2. But before applying
this see that the foundation Is proper
~ set. a very important matter, for.
unless the No. 1 Is properly rolled the
second coating cannot be made MS
light as II should be.
In laying down the NO. z see TO
nave 1t as nearly one grade as possible
avoiding any No. being mixed with
1t; otherwise there VIII always be de-
pressions On the surface, and no mat
ter how much work Is put on 1t the
first wet day and little heavy traffic
Will show them up In water pools. Hav-
ing laid the No. 2. which should be
about or inches In depth, and be-
fore commencing to roll see that the
entire surface Is even, for 1t cant be
expected that the roller will make 1t
SO; rolling Will, smooth 1t, OF course,
but that VIII be all and the depres

soil or road scrapings. as ! already
mentioned, and water 1t well; apply
even more water In this case than FOR
