Abstract

"Four pavement sections were investigated using ground penetrating radar (GPR) and Ultrasonic Surface Wave (USW). The objective of this research was to compare the effectiveness of two non-destructive geophysical tools, GPR and the PSPA, in assessing the condition of the pavements, composed of different construction materials. The GPR data were acquired using a 1.5 GHz antenna along five traverses spaced at two ft. intervals approximately 1000 ft. long. On the other hand, the PSPA data were acquired at the stations spaced at 1000 ft. along the five GPR traverses. Core samples were collected at each site to constrain the interpretation of the acquired geophysical data. The sites include section US 63 about three miles north of Rolla, US 54 in Camdenton County, MO 179 in Jefferson City, and HWY U in Dent County. The types of pavement in these sites were, asphalt concrete overlaying portland cement concrete (AC/PCC), and full-depth asphalt concrete (AC) pavements or full depth bituminous mix (BM).

Based on the acquired and analyzed data of the GPR and PSPA, the data of both tools correlated reasonably well. The PSPA technique successfully measured the elastic modulus and the thickness of pavement and detected horizontal flaws (e.g. debonding and delaminations). Similarly, the GPR technique successfully measured the thickness of pavement and detected horizontal flaws (e.g. debonding and delaminations) within the pavement. The research demonstrated that both non-destructive geophysical tools (GPR and PSPA) are effective in assessing the condition of different types of pavement."--Abstract, page iii.
