135 C H A P T E R 4 Conclusions and Suggested Research The research team identified and collected data on over 400 LTPP sections to form the dataset on which the analysis was based. The number and diversity of the sections was sufficient to examine the study objective and determine a general conclusion.

137 • Eliminate extreme LTPP sections, such as under designed sections to accelerate fatigue and over designed sections to isolate the influence of climate. These sections do not represent typical pavement performance and create some abnormal skew in model development.
