Abstract:ODOT selected a relocation of US Route 30 near Wooster
in Wayne County, the WAY-30 project, as the site for
testing long life pavements. The eastbound lanes were
constructed with a long-life Portland Cement Concrete
(PCC) pavement, and the westbound lanes had an asphalt
concrete (AC) perpetual pavement design. The purpose of
the study was to evaluate these long life pavement design
procedures as alternative pavement design methods. These
design methods have been rapidly gaining acceptance in the
United States. The perpetual asphalt pavement concept uses
mechanistic-empirical design procedure which requires
accurate mechanical properties of materials, traffic, and
environmental data as input to predict pavement responses
and distresses. Using input data and pavement response
models, the thickness of each pavement layer is determined
to keep certain pavement responses at critical locations
within limiting values for perpetual performance. Design of
long-lived concrete pavement also requires accurate
material properties.
