with housing conditions through
out the country only slightly inn
proved, especially in the larger
cities, and with the continued de-
sire on the part Of most city dwells
ers to have their homes in subur-
ban or residential sections instead
Of IN the heart Of a city. the sub
ject Of developing new residential
areas has come to be Of great I'm
portance among city engineers and
city planners.
To be successful. new home
areas must be beautiful and at
tractive as well as within q con-
venient distance Of the average
persons place Of work or busi-
ness. In making these new real
estate sections beautiful. realtors
and city engineers have found that
the problem Of paved streets Is one
of the first to be solved: and after
considerable study and planning,
they have decided that the type Of
pavement in a newly developed
home area must have these fea-
lures:
I. A pavement easily and quickly
constructed.
2. Economical and low in first
cost.
3. Beautiful in appearance and
suitable for the traffic II is to un-
dergo
Aspf1hIt Mncadam Praised.
A pavement which has all these
features and has proved 1t is ideal
for the purpose Is asphalt ma
cadam. Extensive use of 1t dur
ing the last decade has resulted
in its adoption by many towns and
municipalities. as well as by real
estate concerns. to pave newl de-
veIoped residential districts. Among
the cities that have used 1t are:
Asheville and Charlotte. n. c.: Bal
timorc. Md. and Chicago, Ill.
Although the daily traffic over a
street in a suburban or residential
district includes numerous vehi-
cles yet the type of traffic Is not the
heaviest. II usually includes
pleasure automobiles or light com
mercial delivery machines. There
fore a more permanent type of
pavement, like sheet asphalt is not
required and the extra cost would
not be justified.
Consequently asphalt macadam
has been most satisfactorily used.
because 1t is durable and lasting
under the type of traffic specified.
and in addition provides a feauti-
ful, noiseless. waterproof pave
ment, perfectly adapted to the
esthetic surroundings of a residen-
tial or suburban district.
Instances OF It's Use.
This type of pavement has also
been used extensively in and sur
rounding large estates and coun-
try homes because of the facility
with which it Is laid and the man
ner in which it harmonizes with
| the usual charming surroundings
Of such places. Several of the most
popular real estate developments
near Charlotte were paved In 1916
with asphalt macadam by the PEN
etration method. and the streets
in this locality have given excel
lent, satisfaction. There are reany
blocks Of the same type OF road
way in the fashionable Grove Park
section Of Asheville and the atten-
ton of public officials and real es-
tate concerns throughout the coun-
try is being directed to these pave
ments as an example of how as
phalt macadam may be used In de-
yeloping new residential areas.
There are two main parts to an
asphalt macadam pavement: 1C The
foundation: (2) the wearing sur
face.
The foundation may be either OF
the following: Macadam or gravel.
Irrespective of type. the foundation
should be solid. compact and Of SUI
fcient depth. and the subgrade un-
der the foundation should be well
drained and solid.
Principal Materials.
Two main materials make up, the
wearing surface of an asphalt
macadam pavement: % Broken
stone: (2) asphaltic cement. .
The steps in constructing the
wearing surface are as follows:
l. Spread clean. coarse, broken
stone over the foundation. This
stone should be from 1 to "a inches
in size, and should be spread so as
to give a minimum thickness OF
IN inches when compacted.
2. Carefully roll the stone which
has been spread. so as to get an
| even contour and obtain the great
