Structural evaluation of rubblized concrete pavements in Iowa
Rubblization is one of the surface preparation techniques before placing a Hot Mix Asphalt (HMA) overlay that involves breaking the Portland Cement Concrete (PCC) pavement into pieces. This paper describes the structural assessment related to the long term performance of rubblized concrete pavements in Iowa. The structural performance of seven representative in-service rubblized concrete paveme...
متن کاملUltrasonic Tomography Technique for Evaluation Concrete Pavements
Ultrasonic tomography is an emerging technology that shows promise for quality assurance/quality control (QA/QC) during construction, or for making rehabilitation decisions in concrete pavements. However, the benefits of this emerging technology have not yet been fully captured for widespread use in highway infrastructure management. Verification of a state-of-the-art ultrasonic tomography devi...
متن کاملNondestructive Evaluation of Thick Concrete Structures
Materials issues are a key concern for the existing nuclear reactor fleet in the United States as material degradation can lead to increased maintenance, increased downtime, and increased risk. Extending reactor life to 60 years and beyond will likely increase susceptibility and severity of both known and new forms of degradation. A multitude of concrete-based structures are typically part of a...
متن کاملRecent developments in concrete nondestructive evaluation
Concrete is a multi-phase composite material which is difficult to inspect using conventional ultrasonic techniques, including those that work well on relatively homogeneous materials such as metals. This paper summarizes recent research that makes use of signal processing techniques to overcome ultrasonic inspection difficulties in concrete. Basic findings from several new laboratory-based NDE...
متن کاملNondestructive Dynamic Testing of Soils and Pavements
Non destructive testing techniques based on the application of dynamic loads on the surface of a soil deposit or a pavement system, and the measurement of the resulting deflection basins or the phase difference between the motions recorded at various receivers have become powerful tools in civil engineering. In many cases, however, the interpretation of the recorded data relies on static analys...
