Structural Factors for Flexible Pavements-Initial Evaluation of the SPS-1 Experiment Final Report
Primary Topic: Flexible Pavement
Description: This report documents a study undertaken to conduct a detailed review of the Long-Term Pavement Performance (LTPP) Special Pavements Study–1 (SPS-1) experiment to determine to what extent it will provide the necessary data to ensure that the objectives and expectations from this experiment are attained. The SPS-1 experiment entitled Strategic Study of Structural Factors for Flexible Pavements is one of the key experiments of the LTPP program. Its goal is to develop improved methodologies and strategies for the construction of flexible pavements. The review concentrated on the core experimental test sections with secondary emphasis on the supplemental test sections that were built by the individual agencies for each SPS-1 project.
