Dept. of TransportationUnited States. Federal Highway AdministrationUS Transportation CollectionThe Total Pavement Acceptance Device (TPAD) is a continuous pavement deflection testdevice. Since the device is designed for total acceptance of pavements, the researchers havecombined the deflection testing with Ground Penetrating Radar (GPR), digital video, and GlobalPositioning System (GPS) technologies. Texas Department of Transportation (TxDOT) will usethe final system for testing both new pavements and those scheduled for rehabilitation.Since the release of the RDDana 1.0 software about three years ago, Texas A&M TransportationInstitute (TTI) made several changes to the original RDDana 1.0 software based on the users\ue2\u20ac\u2122comments. TTI added new features, fixed some small bugs, and made the current software morestable and easier to use. After all these updates, the researchers propose to rename the RDDanasoftware to TPADana, and define this new software as version 2.0. They made the followingmajor updates for TPADana 2.0:- Previously, the VC++6.0 compiler coded the old RDDana, but the new TPADana isupdated to the Microsoft DOT.NET VC2010 compiler.- The old version can analyze only one sensor but the new software automaticallyanalyzes all three sensors.- Added a new interface that will select which sensors must be shown on the chart.- Added a new interface to define a subset of the data.- On the View Type 1, user can input the detail and sub-detail chart\ue2\u20ac\u2122s range.- Added a new calculation feature of load transfer factor when sensor passing over ajoint.- Added control to show or not show the GPR data on the data view.- Added functions to show the reference mark or stationary number with DMI (DistanceMeasuring Instrument).- Always save the last project to help the user load data quickly.This user\ue2\u20ac\u2122s manual describes the data processing system, and uses the data collected in a 2012survey of US 287 in the Wichita Falls District. The executable load module for this software andthe associated data from US 287 are supplied with this manual
