Abstract:

This project is based on the previous research (0-1828 "Feasibility Study on Non-destructive Testing Technique to Measure PCC Pavement Thickness"), which provided information and a rudimentary radar system that may be able to be used to measure concrete pavement thickness during the curing stage. The technique utilizes a ground couple, pulse wave radar system. However, the system needs further improvement to be useful in the field. In this study, new pulse generator and new antennas are developed. The software of information extraction and thickness calculation is established. Concrete slabs of different thickness are constructed and used to testify the system. The experimental results on the slabs in the lab and on the field are presented. The tested results show that the thickness of concrete slabs can be determined non-destructively in a few milliseconds with an accuracy of 0.5 inches. The range of the thickness measurement reaches 16.5 inches without steel rebars. The developed technology can also be applied to the asphalt pavement for thickness measurement.
