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.

    To the One Who loved me, died for me and has been raised. (Bible 2 Corinthians 5:14-15) Acknowledgements In this age, with the next millennium fast approaching, no one can carry out research work alone. Therefore, the author would like to show his appreciation to the many people who assisted with this study. First, I would like to give thanks to my supervisor Dr. P. L. Domone, who helped with this work, gave valuable suggestions and also corrected my written English patiently. I also appreciated Dr. Y. Xu's kind suggestions and encouragement, and both Dr. K. Ozawa and Dr. J.C. Liu supplied useful information concerning this study. I also enjoyed discussing this research work with my junior colleagues: Mr. V. Sheikh, Mr. E.M. Ahmed and Mrs. J. Jin. Furthermore, Mr A. Tucker and Miss H. Kinloch carried out several mixes concerning the early strength of SCC as their final year project under my guidance. The help I received from the technical staff of the Elvery Concrete Technology Laboratory cannot be ignored, especially from Mr. 0. Bourne and Mr. M. Saytch. Furthermore, I would like to acknowledge the scholarship from my government, without which the dream of studying in this country could not have come true, after having spent 12 years teaching. I especially want to give thanks to my family - my mother, my wife Priscilla and May and Boaz for their support. I owe them very much. I also appreciated the care from the saints in the church - it is impossible to list all of them.

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.

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.

V úvodní části je popsána definice architektonického betonu a také výhody a nevýhody jeho realizace. V dalších kapitolách jsou uvedeny charakteristiky, dávkování či chemické složení vstupních materiálů. Kromě návrhu receptury je důležitým parametrem pro vytvoření kvalitního povrchu betonu zhutňování, precizní uložení do bednění a následné ošetřování povrchu. Popsány jsou také jednotlivé druhy architektonických betonů, jejich způsob vyrábění s uvedenými příklady na konkrétních realizovaných stavbách. V praktické části byly navrženy 4 receptury, kde se měnil druh nebo dávkování vstupních surovin. Při tvorbě receptur byl důraz kladen především na minimální segregaci čerstvého betonu a omezení vzniku pórů na povrchu ztvrdlého betonu.

Abstract This diploma thesis focuses on the influence of properties of feedstocks for the production of quality surfaces of architectural concrete. The introductory part describes the definition of architectural concrete with the advantages and disadvantages of its implementation. In the following chapters, the characteristics, the dosage or the chemical composition of the input materials are given. Besides the design of the mixture, important parameters for the creation of a quality surface of concrete are compaction, precise placement in formwork and subsequent treatment of the surface.

    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.

The southern Toll Plaza was located at the Jefferson Parish terminus of the Lake Pontchartrain Causeway. The Northern Terminus of the Lake Pontchartrain Causeway is located at 30.365 and -90.094167. The Southern Terminus is located at 30.02 and - 90.153889. This information was acquired using Google Earth imagery. There are no restrictions on the release of this information to the public.

Owner: Greater New Orleans Expressway Commission Present Use: Vehicle Bridge Significance: When completed in 1956, the Lake Pontchartrain Causeway was the world’s longest bridge. This record was broken by completion of the parallel span in 1969. At 23.87 miles long, the Causeway is the world’s longest continuous span over water. The prestressed, pre-cast concrete structural system displays mid-twentieth century technology that typifies modern bridge construction techniques. In addition, the Causeway is significant in the development of the Jefferson and St.
