The PAVECHECK data integration and analysis system was developed to merge Falling Weight Deflectometer (FWD) and Ground Penetrating Radar (GPR) data together with digital video images of surface conditions. In project 4495, the earlier system has continued to be expanded with new capabilities. This report provides an updated user's manual for the new program. It is accompanied by a CD that contains an executable program to load the software, along with two test data sets. One data set includes a folder called US77 which contains files of GPR and video images. These data is the typical raw data collected in the field. These files are used to demonstrate how data can be loaded and viewed within PAVECHECK. A second data set named ANNEX is also loaded. This complete data set includes FWD and photos of pavement cores. This data set is used to demonstrate the full capabilities of PAVECHECK. This system has tremendous potential to assist Texas Department of Transportation (TxDOT) engineers with future forensic and pavement rehabilitation studies. The PAVECHECK framework can also assist in future pavement layer data base efforts and in documenting and evaluating the performance of research test sections.
