New Road Nomenclature.

Advancement In the science OIL road
building is accentuated by the action
of the committee on asphaltic and BIZ
luminous pavements, of the Organi-
cation of City Oficials for Standard
izing Paving Specifications, which was
formed recently at Chicago.
According to reports of discussions
in the committee. and as partly shown
in the report. roads constructed from
broken stone and bituminous mater.
ials are separated into two classes,
"bituminous macadam" and bitumin-
Gus concrete" A bituminous mac.
adam road is defined as one con.
structed of broken stone of the vari-
Gus sizes commonly used in macadam
roads, with sometimes sand and grav-
ell, to which has been applied btu
minous material by what is known as
the penetration method" l. e., the
application of the bituminous mater
ial, either hot or cold, to the surface
of the road after the stone has been
| placed in position and rolled.
A bituminous concrete road, in diff
ferentiation from a bituminous mac
adam road Is defined as one built OF
a mineral aggregate, made up of
! broken stone, gravel and sand in vari-
Gus combinations, mixed with bitum-
inous material before being placed
in the roadway. This definition does
away with the necessity for describ-
ing a road as one built by the mix
ing method" when reference is made
! to one where stone and bitumen have
been mixed, either hot or cold, before
being placed in position. 1t is
thought that the segregation OF
names will simplify methods of ex-
| preston, so as to make them more
readily understood. and also to bring
them in accord with the facts.
1t Is urged that road can only be
considered q macadam road, when
the stones are placed upon the
ground, rolled and binder applied.
Primarily this binder consists of
stone dust, washed into the crevices
by means of water. Obviously to
fill up the interstices with bitumen
would make a "bituminous mac
adam" No mention is made by the
committee of fact that this particu-
lar appellation is copyrighted by
company making patented pavements
as one of its trade names"
Bituminous concrete, on the con-
trary, has nothing in common with
macadam in any way, except that the
same materials enter into its mineral
aggregate. Bituminous concrete, like
cement concrete, Is, and must be.
made by thorough mixing of the
materials, to the end that the parti.
cles of the aggregate shall be thor.
oughly and entirely covered by the
cementing material, so that, when
placed in position and compressed,
a dense and solid mass is formed pos.
sessing the requisite qualifications for
a road surface.
Such changes or developments In
nomenclature are the inevitable re,
suits of the progress made possible
by constant experimentation in the
science of highway construction.
They are one Of the indices of ad.

The action of the Alabama Good
Roads Association, at its recent con.
vention at Montgomery, in appoint.
ing a committee on legislative candi'
dates, Is case in point. The asso'
citation has decided upon a system oi
improved roads, with State aid, and
other progressive ideas. At the Mont.

Material candidates were invited to
express their views on the subjecr.
and they did so in manner which
indicated to the members of the as
ISOLATION that which ever may be
elected the good roads measures will
be treated favorably by the executive,
The legislature, however, which Is
to be elected in November, is as yet
an unknown quantity. The members
to be elected are not even placed In
nomination. 1t is the function of this
legislative committee to ascertain the
sentiment Of every candidate on the
subject OF good roads, and report
same to the convention in Birming'
ham in October for action. The plain
intimation is that the association will
assist in the election OF those who
favor good roads for Alabama. and 10
the defeat of those who do not.
Good roads advocates in some other
States. who have long been endeav'
oring to secure better road laws fol
theii commonwealths, might find the
example of the Alabama association
worthy of emulation.-Good Roads
