This thesis presents an economic comparison of three different
highway networks which serve an area of 64 miles by 83 miles in size.
Each network is designed to carry the same traffic between any two
towns but is different in total length.
Costs of right of way, excavation, pavement and...
The objectives of this investigation were to determine the effect
of pulverization on the strength, durability and swell characteristics
of a lime stabilized clay soil. Samples were prepared with three different
gradations which represented the pulverization of the soil.
Maximum clay lump sizes of 3/4", 1/2" and passing #4 sieve...
This thesis presents an economic analysis for a proposed toll
road which is to separate different types of traffic such as pedestrians,
slow speed vehicles and high speed motor vehicles, and to
divert through traffic from the local roads. The use of a toll road
usually provides significant savings in...
The purpose of this study was to investigate an application of
statistical concepts to quality control of highway construction. The
application was presented qualitatively and demonstrated quantitatively
by an investigation of asphalt content in asphalt concrete.
For the example, an Oregon State Highway Project was
sampled and tested. The average...
The central purpose of this comparison was to determine the congruence
or difference between two teaching techniques, the programmed
multimedia approach and the traditional teaching method as used in presenting
drug information to eighth grade students in the Mankato,
Minnesota school district. The population sample consisted of 391
students enrolled...

Water source heat pumps are increasingly being used for residential
and commercial space heating. Typically, these heat pumps are capable
of both heating and cooling, and historically the design emphasis
has been on improving the units' cooling performance. Recently,
there has been more interest in improving the heating performance,
however,...
This study investigated the effect of first aid instruction on
college students' attitudes toward safety. It evolved from previous
studies of the relationship between first aid and accidents in Canada
and the United Kingdom. These earlier studies were concerned with the
effect of first aid training on accident rates. The...
