SPR-4623: Improved Light Weight Deflectometer Test (LWD) and Analysis

This project aims to establish a specialized testing program for the determination of maximum LWD deflection criteria in lieu of field test sections. The deliverables are: (1) Laboratory LWD equipment, which will be integrated into the Indiana Department of Transportation (INDOT) Division of Research & Development (R&D) specialized testing program; (2) a manual of standard procedures for operating and calibrating the laboratory LWD equipment; and (3) an addendum to the manual of laboratory LWD standard operation and calibration procedures that specifies standard procedures for the interpretation and analysis of laboratory LWD test data.
