Project Title: Use of Fibers in Concrete Pavement 16. Abstract Continuously reinforced concrete pavement (CRCP) is a major form of highway pavement in Texas due to its increase in ride quality, minimal maintenance, and extended service life. However, CRCP may sometimes experience pavement distress that results in early failure, either due to under-design or the use of poor construction materials. Significant effort has been made to improve the performance of some of these materials (e.g. siliceous river gravel) to achieve an acceptable level of performance but has been unable to provide a practical solution. This research study investigates whether fiber reinforcement may solve some of the problems associated with siliceous river gravel, particularly spalling.

  • Proposing a New Method Based on Image Analysis to Estimate the Segregation Index of Lightweight Aggregate Concretes
    materials Article Proposing a New Method Based on Image Analysis to Estimate the Segregation Index of Lightweight Aggregate Concretes Afonso Miguel Solak 1,2 , Antonio José Tenza-Abril 1 , Francisco Baeza-Brotons 1 and David Benavente 3,* 1 Department of Civil Engineering, University of Alicante, 03080 Alicante, Spain; [email protected] (A.M.S.); [email protected] (A.J.T.-A.); [email protected] (F.B.-B.) 2 CYPE Ingenieros S.A., 03003 Alicante, Spain 3 Department of Earth and Environmental Sciences, University of Alicante, 03080 Alicante, Spain * Correspondence: [email protected] Received: 18 October 2019; Accepted: 1 November 2019; Published: 5 November 2019 Abstract: This work presents five different methods for quantifying the segregation phenomenon in lightweight aggregate concretes (LWAC). The use of LWACs allows greater design flexibility and substantial cost savings, and has a positive impact on the energy consumption of a building. However, these materials are susceptible to aggregate segregation, which causes an irregular distribution of the lightweight aggregates in the mixture and may affect the concrete properties. To quantify this critical process, a new method based on image analysis is proposed and its results are compared to the well-established methods of density and ultrasonic pulse velocity measurement. The results show that the ultrasonic test method presents a lower accuracy than the other studied methods, although it is a nondestructive test, easy to perform, and does not need material characterization. The new methodology via image analysis has a strong correlation with the other methods, it considers information from the complete section of the samples, and it does not need the horizontal cut of the specimens or material characterization.

  • Arizona Historic Bridge Inventory | Pages 164-191
    NPS Form 10-900-a OMB Approval No. 1024-0018 (8-86) United States Department of the Interior National Park Service National Register of Historic Places Continuation Sheet section number G, H page 156 V E H I C U L A R B R I D G E S I N A R I Z O N A Geographic Data: State of Arizona Summary of Identification and Evaluation Methods The Arizona Historic Bridge Inventory, which forms the basis for this Multiple Property Documentation Form [MPDF], is a sequel to an earlier study completed in 1987. The original study employed 1945 as a cut-off date. This study inventories and evaluates all of the pre-1964 vehicular bridges and grade separations currently maintained in ADOT’s Structure Inventory and Appraisal [SI&A] listing. It includes all structures of all struc- tural types in current use on the state, county and city road systems. Additionally it includes bridges on selected federal lands (e.g., National Forests, Davis-Monthan Air Force Base) that have been included in the SI&A list. Generally not included are railroad bridges other than highway underpasses; structures maintained by federal agencies (e.g., National Park Service) other than those included in the SI&A; structures in private ownership; and structures that have been dismantled or permanently closed to vehicular traffic. There are exceptions to this, however, and several abandoned and/or privately owned structures of particular impor- tance have been included at the discretion of the consultant. The bridges included in this Inventory have not been evaluated as parts of larger road structures or historic highway districts, although they are clearly integral parts of larger highway resources.

    BRIDGE INSPECTION AND INTERFEROMETRY by JOSEPH E. KRAJEWSKI A Thesis Submitted to the Faculty of the WORCESTER POLYTECHNIC INSTITUTE in partial fulfillment of the requirements for the Degree of Master of Science in Civil Engineering May 2006 APPROVED: Professor Leonard D. Albano, Advisor ________________________________ Professor Cosme Furlong __________________________________________ Professor Malcolm Ray ____________________________________________ Professor Frederick Hart___________________________________________ ABSTRACT With the majority of bridges in the country aging, over capacity and costly to rehabilitate or replace, it is essential that engineers refine their inspection and evaluation techniques. Over the past 130 years the information gathering techniques and methods used by engineers to inspect bridges have changed little. All of the available methods rely on one technique, visual inspection. In addition, over the past 40 years individual bridge inspectors have gone from being information gathers to being solely responsible for the condition rating of bridges they inspect. The reliance on the visual abilities of a single individual to determine the health of a particular bridge has led to inconsistent and sometimes erroneous results. In an effort to provide bridge inspectors and engineers with more reliable inspection and evaluation techniques, this thesis will detail the case for development of a new inspection tool, and the assembly and use of one new tool called Fringe Interferometry. i ACKNOWLEDGMENTS I wish to sincerely thank my advisor, Professor Leonard D. Albano, for his encouragement, suggestions, patience and help in writing this thesis. His willingness to let me go beyond the realm of Civil Engineer and into the far away world of Interferometry (where few if any Civil Engineers have been) is something I will never forget.
