“…The study by Popovics et al (1998) also confirmed that the P-wave velocity is significantly affected by the moisture content of the concrete specimen. Higher moisture contents will result in increased P-wave velocity.…”

Prepared in cooperation with the Indiana Department of Transportation and Federal Highway Administration. AbstractPerformance-Related Specifications (PRS) are specifications that base pavement acceptance and pay adjustment on the projected performance and predicted life-cycle cost (LCC) for a specific pavement. PRS relate measurable quality characteristics with pavement performance through computer simulations that incorporate physical distress models. Previously, work at ERES consultants by Darter and co-workers developed prototype PRS for jointed plain portland cement concrete pavements (PCC) through Federal Highway Administration (FHWA) through a series of research projects. However, before this research program began, pavements have not been constructed using these specifications.This report describes the Indiana Department of Transportation's (INDOT) experience with developing and implementing the first and second Level 1 PRS projects during the re-construction of a portion of I-465 east of Indianapolis and I-65 north of Clarksville, respectively. This report includes an overview of the concepts behind PRS, the process of developing a Level 1 PRS, lessons learned from implementing the first PRS in the construction of the pavement outside Indianapolis during the summer of 2000, lessons learned from implementing the second PRS in the construction of the pavement outside Clarksville during the summer of 2002, the use of non-destructive testing procedures to obtain measures of pavement quality, sample specifications, and conclusions and recommendations. In general, this specification was well received by both the agency and the contractors. It is believed that lessons learned on these projects will enable future modifications to the development of performance related specifications with the hope that these specifications will enable longer lasting, more cost effective pavements to be constructed. Unfortunately, prescriptive specifications failed to address the acceptable variability that can occur in the construction of concrete pavements. According to Hughes (1996), in the 1960's virtually no materials or construction properties met the specifications 100% of the time and some met the specifications less than 50% of the time. Furthermore, prescriptive specifications did not always provide the desired end results, even when properly followed (Chamberlin 1995).To address these deficiencies, statistical quality assurance specifications were developed in the 1970s. These specifications were spurred on by two factors: the results of the American Association of State Highway Officials (AASHO) Road Test (1956Test ( -1962 and the growth of the interstate highway system (Chamberlin 1995). Quality Assurance (QA) specifications replaced some of the prescribed methods with descriptions of desirable material properties (Kopac 2002).Also, QA specifications helped to accommodate technological innovation that would have otherwise been prevented by method specifications. Contractors increased their control over the...

“…On the other hand, nevertheless of constant stress state, an usual velocity measurement error of a conventional time-of-flight (TOF) method, which is commonly used for wave velocity measurement of concrete, is often higher than 1% [6]. Obviously it is inacceptable to monitor the change of stress state in concrete using TOF based ultrasonic wave velocity measurement.…”

In this study, we examined the applicability of coda wave interferometry (CWI) technique, which was developed to characterize seismic waves, to detect and evaluate change in the velocity of ultrasonic waves in concrete due to acoustoelastic effect. Ultrasonic wave measurements and compressive loading tests were conducted on a concrete specimen. The measured wave signals were processed with CWI to detect and evaluate the relative velocity change with respect to the stress state of the specimen. A phase change due to the acoustoelastic effect of concrete was clearly detected in the late-arriving coda wave. This shows that the relative velocity change of ultrasonic waves in concrete due to the acoustoelastic effect can be evaluated successfully and precisely using CWI.

Zerstörungsfreie Prüfung von jungem Beton mittels einer Ultraschallreflexionsmethode

Die zuverlässige und zerstörungsfreie Bestimmung der Eigenschaften jungen Betons ist ein entscheidender Faktor für den Erfolg und den Fortschritt vieler Bauvorhaben. Der vorliegende Aufsatz beschreibt eine neue Methode zur Charakterisierung zementgebundener Werkstoffe in jungem Alter. Die Methode beruht auf der Messung des Reflexionskoeffizienten (bzw. des Reflexionsverlusts) hochfrequenter Scherwellen an der Grenzfläche zwischen einer Stahlplatte und z. B. Beton. Die beschriebenen Versuche haben gezeigt, daß die Reflexionsmethode in der Lage ist, den Erstarrungs‐ und Erhärtungsprozeß von Beton qualitativ und quantitativ zu beschreiben. Über einen ersten, erfolgreichen Feldversuch wird berichtet.
