This report describes the use of the MODULUS 6.0 FOR WINDOWS software. The MODULUS 6.0 FOR WINDOWS software is a software system used by the Texas Department of Transportation (TxDOT) to process Falling Weight Deflectometer (FWD) data. The system has been used since the early 1990s to perform structural evaluation of pavements and to provide layer moduli values for structural design. Project 0-1869 expanded the analysis and design capabilities of the system. One important aspect of this project was to move the improved system to the Windows environment, making it more user-friendly.
