• Abstract:
  TxDOT Project No. 5-6005-01, Statewide Implementation of Total Pavement Acceptance Device (TPAD), was completed on August 31, 2014. This deliverable discusses the improvements made to the RDD system on the TPAD. This work was performed from January 2013 to August 2014. The first improvement involved the air pressure control system on the rolling sensors. The second improvement involved modifications to the towing frame used to position and raise/lower the rolling sensors.
