• Abstract:
  In December 2005 Mississippi Department of Transportation (MDOT) initiated State Study No. 182 on review ; and evaluation of ground penetrating radar (GPR) technology. This Phase I study has reviewed GPR equipment ; and data interpretation methodologies used for nondestructive determination of pavement layer thickness ; values. An extensive literature review was supplemented by review reports from two study consultants, and a ; comprehensive GPR technology evaluation survey of GPR manufacturer and users in the United States and ; abroad. There is adequate experience available with data interpretation methodologies and FCC certified or ; “grandfathered” GPR technologies for reliable and reasonably accurate field assessment of asphalt pavement ; layer thicknesses. The MDOT is planning to evaluate this technology together with the nondestructive falling ; weight deflectometer (FWD) tests to enhance the evaluation of asphalt highway pavements and rehabilitation ; design. A preliminary cost-effectiveness study shows a high benefit/cost ratio of 80-200 based on overlay ; thickness design of a 10-mile asphalt pavement section. Based on favorable assessment in this study, a follow ; up larger Phase II study is recommended for field evaluation of the candidate GPR technology with 1- GHz and ; 2-GHz air-launched horn antennas. A ground-coupled 400/500 MHz antenna is also recommended considering ; 30-inch or thicker pavements and the lime-treated subgrade layer. A pilot field study in Phase II should be ; conducted on a test section of a candidate asphalt highway pavement. Upon successful results and validation of ; improved pavement evaluation and resulting potential cost savings, the MDOT will consider implementing the ; GPR technology for routine use.
