• Abstract:
  During the first year of Project 0-6005, significant progress was made towards developing the Total Pavement ; Acceptance Device (TPAD). The TPAD will be a multi-function device that will be used to survey continuously ; along pavements at speeds in the range of 5 to 10 mph. The test functions will include those associated with ; Rolling Dynamics Deflectometer (RDD), ground penetrating radar (GPR), DMI and high-precision differential ; GPS, and surface temperature measurements, as well as digital video imaging of the pavement and right-of-way ; conditions. The basic moving platform for the TPAD was selected and initial prototype tests were conducted at ; the TxDOT Flight Services Facility at ABIA. Progress was made in developing: (1) improved rolling sensors and ; associated data analysis methods commensurate with the target testing speeds and (2) an integrated data
