TYPE I UNBOUND GRANULAR BASE SYNTHETIC REFERENCE SAMPLE PROGRAM
Strategic Highway Research Program (SHRP) Protocol 46 was the specified test procedure for laboratories performing resilient modulus tests on samples of unbound granular base material obtained from Long-Term Pavement Performance (LTPP) field sites. P46 requires a test system that includes a triaxial pressure cell component, a closed loop electro-hydraulic repeated load component, and certain load and specimen response control, measurement, and recording components. Two elements of P46 testing were particularly important: verification that the system was calibrated and yielding reasonable results and a practical means of performing quality checks on a daily or more frequent basis. Worksheets, supporting data, analyses, final comments, and conclusions are presented.
