BituminOus Gravel Road Mile
age eNar 1900

Bids on bituminous treatment OF
$50 miles of graveled trunk high
ways, will be received by the Min
nesota Highway department March
IL, Commissioner G. M. Babcock
announces. Another $50 miles
more or less, may be added to the
program later in the season, 1t is
announced, Minnesota now has
1,15O miles of bituminous travel in
the trunk highway system and the
1881 program will bring the tota
close to 1900.
Included in the stretches on
which bis for oiling or tarrine
will be taken this month are L. II
No. % from Sank Centre to five
miles east of Glenwood a distance
of 1913 miles.
The tentative schedule on which
bids will be received March II calls
for figures on 12,70O,0O0 gallons OF
material. Separate figures will be
taken on material delivered at the
nearest station to each project, and
on application of the material. In
addition to the treatments, the
schedule also includes 622 miles OF
retreatment of routes previously
treated. Refreshments, on the aver
age, are required two out of three
years.
While bituminous materials
come in three general classes, oil,
tar and asphalt, there are several
grades in each class. Before any
gravel road is treated, there is a
careful study of traffic conditions,
sub-soil, cost of materials, and
other factors, to determine the
right grade and amount to apply.
Using the wrong grade, too much
or too little, or any error in the
method of application, may result
in a road surface worse than I'M
treated road.
Bituminus treatment is used for
permanent surfacing on many
routes earring medium heavy traf-
fic, and also as temporary ex-
pedient on roads which carry very
heavy traffic but which cannot be
paved Immediately. Treated gravel
roads are dustless and in many re-
spects equal to pavement, but
when the subgrade is soft in the
spring it is often necessary to re-
strict the size of loads using these
roads.
During 1890 the Minnesota High
way department gave new oil
treatments to Isl miles at an aver
age cost of s1,357, and oil retreat
ments to 260 miles at an average
cost of $692 per mile. Seventy
miles were given new tar treat
ments, the average cost being ST.
1888, and 17S miles retreated at an
average cost of 1897. Asphalt was
used on miles of new treatment.
average cost $1,637, and 8 miles of
retreatment average cost 1926.
These costs include the new gravel
needed and work necessary to
spread and mix the gravel into bin
der.
The season for bituminous work
in Minnesota is limited to about
three months as the material can
be applied only in warm, dry
weather Is
