The last and most striking depart
ure from the old practice is what is
known as the IMPERIAL PAVE
MENT, three pices of which have been
laid. In Harrison, Hudson county,
one block was treated as follows
The earth composing the road was
ploughed, thoroughly narrowed and
formed up to grade, after which a
binder, composed of asphaltum, fuxed
with lighter oil, was applied hot by
means of a steel bodied sprinkling
wagon. This wagon was drawn over
the prepared surface and the hot as
phaltum sprinkled on it. Then the
harrowS were again used until the
binder was thoroughly mixed through
the mass. A mould plow was next
used to turn this impregnated mass
under, at the same time bringing
fresh earth to the surface. This, in
turn, was treated in the same manner
as the first surface, and the asphalt
um thoroughly mixed as before. The
result was a mass of earth thoroughly
impregnated with aSphaltum to a
depth of about five or six inches. The
really new feature of the work was
then introduced; that is, the rolling
tamper This is machine composed
of a series of cast iron sprocket
wheels loosely revolving upon an
axle. This machine weighs about
five thousand pounds, and each tooth
has surface area of about eight in
ches. The machine is hauled over
the seprface of the road and the teeth
sink p the full depth of the mixture,
compacting the bottom first. Its con-
tinued passage congresses more and
more of the mass until the machine
with is toothed wheels rides upon the
surface, which, by this time, resem-
bles a piece of tough leather. This

ton steam roller and lastly polished
with five ton roller. Just before
the final finish, coating of sharp
sand or screenings is spread upon the
surface and rolled in. THUS PRE-
VENTING ANY TENDENCY TO
WHICH IS ONE
OF THE GREATEST OBJECTIONS
TO OTHER ASPHALT PAVEMENTS.
SO employd at Westville, Gloucester
county, and Landing, Morris county,
and, in each instance, has given much
satisfaction. That at Landing, in
particular, which was the last laid,
has met with nothing but praise from
all those who have seen it.
In number of the counties, and
in several municipalities of our
State, oils, tar products and patented
substances for surface treatment and
dust preventatives have been exten-
sively used. The results have been
varied, and, at the best, but tempor
ary. The State department has given
but little encouragement to this form
of treatment.
In reviewing the experimental work
accomplished the past year, the re-
suls would indicate that the use OF
heavy asphaltum oil as binding sub
stance will prove the most desirable,
economical and practical in future
construction work. Furthermore,
it is probable that in the advancement
of road building during the coming
year our standard specifications will
be modified so as to provide for the
use of this or some kindred material.
We have in course of preparation
set of specifications which we propose
distributing among the various county
Commissioners, Boards of Chosen
Freeholders, Road Supervisors and
Road Overseers. In the specifca-
tions we will recommend that in re-
pairing roads they should first be
scarified to depth OF at least two
inches, and, after the removal of all
foreign matter be treated with some
binding substance similar to that
specified for use in new construction.
In fact, in the expenditure of the
moneys over which this department
has jurisdiction, we will insist upon
the adoption of this plan of treatment.
While the first cost is greater, the re-
suits are much more permanent, and,
in great measure will relieve the
Objectionable featurs of our present
stone roads.
