In line with its policy of inforp-
Ing the public. especially those who
pay the taxes. as to the economies
that may be effected in the con-
struction Of highways, as well as
the propaN methods of construction,
the ! United States government.
through the Bureau of Public

has just completed for free distri-
button and use in motion-picture
houses, as well as at conventions,
ehautauduas and educational con-
ferences throughout the country.
two reels of pictures showing In de-
tail the construction the various
types of asphalt roads. The pic
lures were exhibited for the first
time at the recent American Good
Roads Congress in Chicago
The pictures were taken last
summer in New York. New Jersey.
Pennsylvania. and other States. un-
der the direction of f. ]. wulff.
senior highway engineer. United
States Bureau of Public Roads, and
E ]. Kelly. of the motion-picture
division, United States Department
Of Agriculture. The pictures were
produced particularly for the pur-
pose Of showing. how the best re-
suits may be obtained in asphalt
construction. They are loaned to
responsible parties free of charge.
except for transportation costs.
The first reel. entitled Building
Bituminous Roads" Indicates the
wide application of bituminous ma
terials in highway construction. II
shows tie character of the btu
minous. materials and demonstrates
the principal laboratory tests used
in determining their suitability for
the varinns types of roads to meet
Various climatic. and traffic condi-
tons. A portion of the reel shows
lin detail all the various steps that
cshculd be taken in surface-treating
" macadam pavement. This sccne
"Opens with a large motor truck
distributor spraying the bitumi-
nous material upon a macadam sur
face in the suburbs of Philadelphia,
Pa. The distributor is followed
closely BY ? horse-drawn wagon
spreading the stone chip covering.
The bituminous macadam pavement
is a type much superior to plain
or surface treated macadam. II:
its. construction the asphalt is
treated and applied either by me-
chanicai or by hand distributors.
The use of the small hand-pour-
ing pots in applying the asphaltic
binder Is demonstrated on a road
near Pittsburgh, Pa. This demon
stration is followed by views show
ing the mechanical distribution of
the asDhalt by motor trucks on a
nroiect in westchester County, near
New York City. The trucks are
first shown loading at a railroad
siding from huge tank cars. They
then leave for the road. where the
material is applied under pressure
at the rate OF one and one-half
gallons to the. square yard. Labor
srs are pictured covering this ma
terial with stone chips. A power
full roller then compacts the pave
ment The road ia then shown, by
the passing of traffic. to be ready
for immediate use. According TO
engineers. one Of the big advan-
tages of asphalt pavements is thai
they can be opened to trafi1c as
soon as constructed.
The second reel. entitled Build
ing Mixed Asphalt Pavements."
shows methods used in construct
ing both asphaltic concrete and the
SneeL asphalt ~ pcs "
This reel contains views of plants
at Pittsburgh, Pa. and Columbus,
n, J.. where the stone, sand, and
asphaltic binder are heated and
mixed. The mix is loaded upon
trucks and hauled to the road.
Here IL Is spread with rakes and
then compacted by a roller. This
picture shows that the mixed types
may also be opened to traffic i'm
nediately after their completion.
The pictures demonstrating the con-
struction Of asphaltic concrete roads
were taken on a new road under
construction between Mays Land
ing and Pleasantville, and leading
into Atlantic City. ". ]. The pic
lures of sheet asphalt CONSTRUCTION
were taken on a road near Column
bus. in Burlington County. N.
This county now has sixty miles u
sheet asphalt roads on a macadan,
base. The pictures show in a novel
way, by means of an animated dts-
rram, the relative proportions oS
sand, stone, and asphalt binder IN
each Of the two types of pavement.
The government pictures offer an
interesting and Instructive add
ton to any motion picture program.
Each reel is approximately 900 feet
long. and about fifteen minutes Is
.eduired for its showing.
