Note : This document is digital این مدرک بصورت الکترونیکی می باشد
Abstract : The United States has the largest roadway infrastructure system in the world.However, this roadway infrastructure is deteriorating every year, causing increasinglyserious hazards. Hence, periodic condition assessment of the roadway infrastructureprovides better preventive and/or corrective planning. Also, continuous monitoring of theunderground condition is necessary for obtaining environmental factor effects ondeterioration. All these will help to preserve the roadway infrastructure integrity andreduce its life-cycle costs. In this dissertation, Electromagnetic (EM) sensors forsubsurface characterization are introduced.Ground penetrating radar (GPR) is used to measure the thickness and dielectricconstant of the highway pavement based on the time lag between the direct wave andsub-layer reflection signal. The frequency-modulated continuous wave (FMCW) GPR is,..tested for theQ1 PC1 bus cardBoth these projects mere sofixare des elopment efforts tonards contributing to dlfferentaspects of Roboucs and lZ1echatronics projects m the Controls and Roboucs Group..
