The Texas Department of Transportation (TxDOT) uses the MODULUS program to process Falling Weight Deflectometer (FWD) data. This system has been used since the early 1990's to perform structural evaluation of the pavements and to provide layer moduli values for structural design. Project 0-1869 expanded the analysis and design capabilities of this system. One important aspect of this project was to move the improved system from the DOS to the Windows@ computer platform. This report provides a user's manual for the new Windows version of MODULUS 6.0. The basic features of the DOS MODULUS 5.1 system have been transferred to Windows. Substantial improvements have been made to the programs, data editing, and segmentation routines.
