The correlations between traftic load distributions and tensile
strains in flexible pavements are discussed in this paper, and
these relationships are compared against theoretical strains computed
from layered elastic theory. Six flexible pavement test sections
at the Minnesota Road Research Project (Mn/ROAD) were selected
for the analysis presented in this paper. Wheel-weight data from
the weigh-in-motion station at the Mn/ROAD site were taken for
a number of time periods during 1995. Weight data distributions
were then matched to temperature-corrected transverse strains
measured at the bottom of the asphalt concrete in the test sections.
Finally, a layered elastic analysis was performed, the results
of which were compared to actual measurements under traflic. It
was found that the measured strains and the strains computed from
the analytical model matched well when the loads were modeled
as dual wheels with constant tire pressure and a varying load
magnitude.
