ISSUE
ASTM C-78 has
a history of being identified as the source of error in determining
the strength of a concrete pavement. There are numerous examples
of results of testing being disputed because of technician error,
field conditions, laboratory curing, etc. The unknown factor in
the test is the impact of the errors on the magnitude of the test
results.
RESEARCH
Research will
be accomplished that will attempt to quantitify the impact of
each of the steps in the test to the magnitude of error introduced
into the test results.
BENEFITS
Engineers, Owners
and Contractors will have access to information that is now speculation.
The research will allow for the stakeholders to evaluate at which
step in the performance of C-78 are exact techniques required
and which steps can be accomplished with variation in techniques
without significant impact on the results.
