NON-DESTRUCTIVE TESTING OF PAVEMENT MATERIALS. FINAL REPORT

The research presented herein ia a feasibility study that utilizes a new technique termed the Fourier Analysis, in the determination of the dynamic properties of paving materials, which includes, granular materials, cohesive materials, asphalt concrete, and cement concrete. The new technique has proven to be successful in other fields and it is studied in this research to see if it will also be successful in the testing of pavements. To assess the response of pavement systems all variables that will affect testing performance and accuracy were investigated and a testing methodology suitable for pavement material was developed. A large number of specimens from both cement and asphaltic concrete were prepared and tested for verification of the applicability of the technique. The specimens were prepared such that a wide variation in properties was presented. This was accomplished by either changing the mix design, or the environmental conditions of the concrete specimens preparation. From this study, it was found that for granular and cohesive materials at strains of above 0.0001%, the dynamic properties were influenced by the type of loading applied. However, for concrete specimens, it was found that the new testing procedure was sensitive to all the variables considered in the preparation of the specimens, except for asphaltic concrete specimens at high temperatures.
