Available in PDF, EPUB and Kindle. Book excerpt: Perpetual pavement design philosophy provides a long-life pavement design alternative. The ability of a pavement design to perform as long-life pavement is subjected to several technical constraints. Throughout the past 10 years, perpetual asphalt pavement designs have been under investigation in several parts of the world. The Canadian climate represents an additional challenge to the success of long-life pavement performance. This project investigated the construction and performance of three pavement test sections that were constructed on Highway 401 in Southern Ontario. The construction phase of this project was completed in 2010. The test sections were equipped with various sensors to monitor the structural performance. The test section included two perpetual pavement sections and one conventional pavement section. The two perpetual pavement designs were identical with the exception of the bottom asphalt layer, which was constructed as a Rich Bottom Mix (RBM) layer in one of the perpetual sections. The three pavement sections were evaluated from a structural point of view through the analysis of the in-situ tensile strain collected from asphalt strain gauges installed at the bottom of asphalt layers under the wheel path. In addition, asphalt material laboratory characterization was undertaken by testing asphalt samples collected during construction of the three test sections. The laboratory testing was performed at the Centre for Pavement and Transportation Technology (CPATT) at the University of Waterloo. The laboratory experimental matrix in this research included dynamic modulus testing, resilient modulus testing and Thermal Stress Restrained Specimen Testing (TSRST). The correlation between various laboratory test results and the collected in-situ tensile strain was evaluated. Several linear regression models were developed to correlate the laboratory test results and the field asphalt temperature with the in-situ tensile strain. Overall, it was found that the perpetual pavement with RBM section had the lowest tensile strain at the bottom of asphalt layers. Also, various models were developed that predict tensile strain at the bottom of asphalt layers by using laboratory test data. An economic analysis was implemented to evaluate the perpetual and conventional pavement designs including a Life Cycle Cost Analysis (LCCA). Furthermore, a sustainability assessment for both design philosophies was executed to evaluate the environmental benefits of perpetual pavement designs. The perpetual pavement designs were shown to provide many benefits over the conventional asphalt pavement designs for usage on Canadian Provincial and Interstate Highways in similar climatic zones with similar traffic loading. The advantages of perpetual pavement design philosophy are not limited to structural benefits, but also extended to economic and environmental benefits in the long term.

Download or read book Urban Transport XXI written by C.A. Brebbia and published by WIT Press. This book was released on 2015-06-02 with total page 733 pages. Available in PDF, EPUB and Kindle. Book excerpt: Urban Transport XXI contains the proceedings of the 21st International Conference on Urban Transport and the Environment. The series of annual conferences organised by the Wessex Institute was first held in 1995. Transportation in urban areas, with its related environmental and social impacts, is a topic of significant concern for policymakers in both municipal and central government and for the urban citizens who need effective and efficient transport systems. Urban transport systems require considerable studies to devise and then safeguard their operational use, maintenance and safety. Transportation systems produce significant environmental impacts and can enhance or degrade the quality of life in urban centres. Clearly the challenge of providing effective and efficient transport systems in urban settings remains an acute concern, with financial, political and environmental constraints limiting the ability of transport system planners and operators to deliver the high quality outcomes expected by the public. Papers cover such topics as: Urban Transport Planning and Management; Urban Transport Strategies; Public Transport Systems; Environmental Aspects; Economic and Social Impact; Safety and Security; Travel Behaviour Studies; Customer Satisfaction; Transportation Modelling and Simulation; Infrastructure Development; Intelligent and Advanced Transport Systems; Transportation Integration; City Logistics; Resilience and Inter-modal Transport Systems; Mass Transport Strategies; Social Impacts; Freight Transport; Railway Systems; Transport Governance and Administration; Port and City; Mobility and Public Space; Life Cycle Management.
Download or read book Electrical Measuring Instruments and Measurements written by S.C. Bhargava and published by CRC Press. This book was released on 2012-12-27 with total page 572 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book, written for the benefit of engineering students and practicing engineers alike, is the culmination of the author's four decades of experience related to the subject of electrical measurements, comprising nearly 30 years of experimental research and more than 15 years of teaching at several engineering institutions. The unique feature of this book, apart from covering the syllabi of various universities, is the style of presentation of all important aspects and features of electrical measurements, with neatly and clearly drawn figures, diagrams and colour and b/w photos that illustrate details of instruments among other things, making the text easy to follow and comprehend. Enhancing the chapters are interspersed explanatory comments and, where necessary, footnotes to help better understanding of the chapter contents. Also, each chapter begins with a "recall" to link the subject matter with the related science or phenomenon and fundamental background. The first few chapters of the book comprise "Units, Dimensions and Standards"; "Electricity, Magnetism and Electromagnetism" and "Network Analysis". These topics form the basics of electrical measurements and provide a better understanding of the main topics discussed in later chapters. The last two chapters represent valuable assets of the book, and relate to (a) "Magnetic Measurements", describing many unique features not easily available elsewhere, a good study of which is essential for the design and development of most electric equipment – from motors to transformers and alternators, and (b) "Measurement of Non-electrical Quantities", dealing extensively with the measuring techniques of a number of variables that constitute an important requirement of engineering measurement practices. The book is supplemented by ten appendices covering various aspects dealing with the art and science of electrical measurement and of relevance to some of the topics in main chapters. Other useful features of the book include an elaborate chapter-by-chapter list of symbols, worked examples, exercises and quiz questions at the end of each chapter, and extensive authors' and subject index. This book will be of interest to all students taking courses in electrical measurements as a part of a B.Tech. in electrical engineering. Professionals in the field of electrical engineering will also find the book of use.
