Structural Factors of Jointed Plain Concrete Pavements: SPS-2-Initial Evaluation and Analysis
Primary Topic: Rigid Pavement
Description: This report documents the first comprehensive review and evaluation of the Specific Pavement Studies 2 (SPS-2) experiment, Strategic Study of Structural Factors of Jointed Plain Concrete Pavements (JPCP), as it exists today. The main objective of this experiment is to determine the relative influence and long-term effectiveness of JPCP design features and site conditions on performance. The evaluation concludes that many important and useful findings and results can be obtained from the SPS-2 sites despite several limitations resulting from not constructing a few of the test sites and a few construction deviations that occurred. In addition, some materials and traffic data are missing from some sites or sections. These data are important to achieving the objectives of the experiment, and are now being sought from the SPS-2 sites. This report will be of interest to highway agency engineers involved in design, construction, and management of the pavements as well as future researchers who will analyze the performance of the SPS-2 sections.
