摘要：Rutting is one of the major load-related distresses in
airport flexible pavements. Rutting in paving materials develop
gradually with an increasing number of load applications, usually
appearing as longitudinal depressions in the wheel paths and it may
be accompanied by small upheavals to the sides. Significant research
has been conducted to determine the factors which affect rutting and
how they can be controlled. Using the experimental design concepts,
a series of tests can be conducted while varying levels of different
parameters, which could be the cause for rutting in airport flexible
pavements. If proper experimental design is done, the results
obtained from these tests can give a better insight into the causes of
rutting and the presence of interactions and synergisms among the
system variables which have influence on rutting. Although
traditionally, laboratory experiments are conducted in a controlled
fashion to understand the statistical interaction of variables in such
situations, this study is an attempt to identify the critical system
variables influencing airport flexible pavement rut depth from a
statistical DoE perspective using real field data from a full-scale test
facility. The test results do strongly indicate that the response (rut
depth) has too much noise in it and it would not allow determination
of a good model. From a statistical DoE perspective, two major
changes proposed for this experiment are: (1) actual replication of the
tests is definitely required, (2) nuisance variables need to be
identified and blocked properly. Further investigation is necessary to
determine possible sources of noise in the experiment.
