• Abstract:
  The MIT-Scan-T2 device is marketed as a non-destructive way to determine pavement thickness on both ; HMA and PCC pavements. PCC pavement thickness determination is an important incentivedisincentive ; measurement for the Iowa DOT and contractors. The thickness incentive can be as much as ; 3% of the concrete contact unit price and the disincentive can be as severe as remove and replace. ; This study evaluated the potential of the MIT device for PCC pavement thickness quality assurance. ; The limited testing indicates the unit is sufficiently repeatable and accurate enough to replace core ; drilling as the thickness measurement method. Further study is needed to statistically establish the single ; user and multi-user/device precision as well as establish an appropriate sampling protocol and PWL ; specification.
