Introduction - Soil Properties: Testing, Measurement, and Evaluation - page 2

soil samples obtained from exploratory borings. However, quantitative
results of both field ( in situ ) and laboratory tests on the samples are nec-
essary to analyze the soil conditions and effect an appropriate design
that is based on actual data. The importance of securing sufficient and
accurate soil property data can hardly be overemphasized.
This topic deals with soil testing procedures, as well as the collection
and evaluation of test data. However, to provide a more complete picture
concerning individual tests beyond Chapter 2, each test is introduced to-
gether with its definition, scope, and objective. A summary is given at the
end of each chapter explaining the method of presentation, typical values,
and engineering uses of test results. In addition, a complete numerical ex-
ample, including necessary graphs, is presented in each chapter so that
students can grasp not only the procedures and principles of each test, but
also the entire process of evaluating applicable laboratory data.
The field and laboratory tests in this topic include virtually all soil
tests that are required and done on a routine basis. All except a very few
procedures follow those of the American Society for Testing and Materi-
als (ASTM) and/or the American Association of State Highway and
Transportation Officials (AASHTO).

In order to standardize the presentation of each laboratory test in
the remainder of the topic, the following format is used for each chapter
beyond Chapter 2:
