Development of an SPS-2 Pavement Preservation Experiment

This report outlines the current availability of the Long Term Pavement Performance (LTPP) SPS-2 experiment – strategic study for structural factors for rigid pavements – and proposes several options for potential future experiments that could be completed with the existing data for a comprehensive study of concrete pavement preservation techniques. The original core experiment sections were utilized in an experiment design comparing multiple maintenance treatments while the supplemental sections were included in a dowel bar retrofit study. Additionally, the proposed experiment could likely be expanded to include using the wealth of existing pavement performance data from the SPS-2 experiment to potentially use the predicted performance curves from AASHTOWARE PavementME as the control sections and thus eliminating the need for paired sections and allowing for doubling of the experimental sections that could be used. This report for Phase I summarizes the work completed thus far evaluating and recommending possible experiments based on existing data.
