Abstract:The overall purpose of this research project as described in
the Executive Summary Report for Volume 1
(FHWA/OH-2010/04A) is to identify flexible, rigid and
composite pavements that have not received any structural
maintenance since construction and are considered to be
performing in either an excellent or an average manner,
and to determine the reasons why excellent pavements
perform better than average pavements. By identifying
these reasons and implementing them into standard
practice, the overall performance of pavements in Ohio
can be improved in the future.
The present report describes the methodology used and the
results obtained in the petrographic examination of cores
taken from twenty Portland cement concrete (PCC)
pavement projects in the ODOT system. The criteria of
selection of the twenty PCC pavements are described in
the Volume 1 Report.
