Abstract:Proper calibration of mechanistic-empirical
(M-E) design and rehabilitation performance
models to meet Texas conditions is essential
for cost-effective flexible pavement designs.
Such a calibration effort would require a
reliable source of pavement material
properties and performance data collected
on a sustained basis.
In this study, the researchers developed a
comprehensive data storage system (DSS)
containing material properties and
performance data for flexible pavement and
overlaid test sections in Texas. A minimum
of 100 flexible pavement and overlay
sections across Texas were monitored, and
data were collected for subsequent
population of the DSS to:
- Serve as a data source for the calibration
of the Texas M-E models and design
software, such as the Texas M-E pavement
design system (TxME).
- Serve as an ongoing reference data source
and diagnostic tool for Texas Department of
Transportation (TxDOT) engineers and other
transportation professionals.
