"Eight electrical resistivity tomography (ERT) and multi-channel analysis of surface wave (MASW) case studies are presented. The objective is to assess the condition of pavement, base, native soil, and rock all the way down to the top of the bedrock. Each segment of road way is approximately 1000 ft. long. The cases include US 63 north of Rolla, US 54 in Camden County, Rte. 179 in Jefferson City, HWY AT in Franklin County, I-55 in Pemiscot County, I-55 in Perry County, HWY U in Dent County, I-35 in Daviess County. In addition, there are only three types of pavement in these sites portland cement concrete (PCC), asphalt concrete overlaying portland cement concrete (AC/PCC), and full-depth asphalt concrete (AC) pavements. Accordingly, the geophysical tools examined different types of pavements with different distress conditions.
Based on the analyses of the acquired ERT and MASW data, the data of both tools correlate reasonably well and generate reliable and comprehensive information about variations in soil and rock rigidity, variations in rock lithology, pattern, placement and density of solution-widened joints and offset of faults, locations of air-filled voids, distribution of dry and moist soil, distribution of clayey soil, and mapping variable depth to top of bedrock. Therefore these technologies can be routinely used by not only the Missouri Department of Transportation but also worldwide agencies in support of its pavement management process.
The research demonstrated that the ERT and MASW methods were effective tools for assessing the condition of pavement. This is the first comprehensive assessment of paved sections of roadway to the best of the author knowledge"--Abstract, page iii.
