Evaluating the Performance of Georgia’s CRCPs using Ground Penetrating Radar (GPR)

The research team proposes conducting a site survey of rebar height at punchout locations before patching is completed this fall and ultimately answer the following three questions: (1) Does the position of rebar (concrete cover size) influence punchouts? (2) Are there any other factors that affect the location and extent of punchouts (i.e., reinforcement ratio, slab thickness, flexural strength, thermal expansion, etc.)? (3) What is the estimated depth of the sublayer and how does the pavement profile affect the continuously reinforced concrete pavement (CRCP) performance, if any? Lastly, the research team will provide the Georgia Department of Transportation (GDOT) with a ready to implement general diffraction theory (GDT) non-destructive test method for the use of ground penetrating radar (GPR) on CRCPs.
