with road building one Of the most
Important topics OF h day in the
Rocky Mountain region and with
knowledge that tho only permanent
-oads viii be OF tho hard surface type.
tho Colorado meeting holds double
l~ignifcance.
Realizing hat the engineers OF the
district in the final analysis nre the
Judges OF the best types. the Colorado
society has invited Mr.. Reed to ad-
iress the organization extensively w
he new industry which the Midwest
and Standard companies arc build
ing in this district.
So important has the subject become
IN the Rocky Mountain region that
he entire meeting Of the Colorado on
yineers will he devoted to the consid-
ration OF this type OF pavement.
every effort will be made TO insure
OF tho largest turnouts OF engi-
aeers that has ever gathered together
n the district
Special invitations are being sont to
ngineers not only in Colorado but 10
tate highway commissioners. state en-
;lneers Inc independent engineering
organizations In all states OF the Rocky
Mounty district.
The program for tho meeting intro
luced h subject as follows:
mfr. l.. a. Reed, a director OF the
Midwest Refining company, and for
nany years in charge of tho refining
peraticns Of the company. will give n
1aper on the preparation OF road oil
nd asphalt giving especial sattention
o the experimental work which has
zen carried on in the development OF
he so-called black oil found in the
Rocky Mountain region. He will dis.
uss the very control maintained nj
| me refinery in turning out material
II uniform physical and chemical prop,
rites.
THE temperature control through.
u tho refining process is OF great.
st Importance. Frequent tests arc
made Of representative samples
throughout the refining so that the
engineer specifying a certain desired
tsphalt or o oil will have a product
which he can depend upon for def,
mite uniform behavior in the finished
highway.
Mr.. Reeds talk will be followed by
5000 feet of moving picture film show.
us Nh' aNNuai laying Ol ullltrenI pes
Of asphaltic highways. Mr.. II. II. Car
penter will direct the discussion OF
these pictures. Two thousand feet Of
these pictures were taken by the Unit.
ed States Bureau OF Public roads for
use as educational films in advancing
highway construction. One thousand
feet has been taken by the Asrhaltic
Association and shows a series of i'm,
pact tests made on different types OF
material used in highway construc,
tion."
The tests on asphaltic pavement
have progressed here until Mt the pres
ent time two stills with a daily capaci-
~ of one tank car are being operated.
Tests being mad OF oil trom black oil
fields OF this vicinity indicate that
there is ample supply of very high
| grade asphaluc base oil in the Warm
Springs and Lander fields for immedi.
ate needs. II the project here con.
tinues TO grow. black oil fields of the
entire state will find an outlet for the
otherwise unused product.
1t is Of special Significance that Mr..
Reed a refining expert, and head OF
the asphaltic manufacturing depart
ment OF the local refineries. will be
given the first opportunity to address
the engineering society on hard sur.
face types of road. in view of the fact
that every state in this district con
templates spending great sums OF mon
ey during the present and coming
years for road Improvement.
