Book Description
Case studies are used to show how theory is applied in practice. In the design and construction process, various models are used – geotechnical, laboratory, analytical, delivery, and economic models as the project is developed from planning to construction. This book explores the use and limitations of these earthwork models to be understood and appropriately applied. This book evolved from an earthworks course to practicing engineers over a 10-year period. Theory alone is not enough. Experience alone without relating back to theory can sometimes be misleading if transferred without understanding the fundamentals. The book benefited from the experiences of those many practicing engineers and the author’s experience in multi-disciplinary consulting companies as well as specialist geotechnical companies and government departments. The basics of soil, rock and compaction mechanics as applied to field conditions are covered. Material typically not covered in other textbooks, include the applications and limitations of associated "standard" laboratory and field testing. Specific chapters are dedicated to excavation, subgrade and expansive clay assessment and treatment. Useful design practices as well as the development and application of specifications is covered. A specification, test or design in one climatic condition or geology may not apply in another.

Book Description
Pavements are engineered structures essential to transportation, commerce and trade, and everyday life. In order for them to perform as expected, they must be designed, constructed, maintained, and managed properly. Providing a comprehensive overview of the subject, Pavement Engineering: Principles and Practice, Second Edition covers a wide range of topics in asphalt and concrete pavements, from soil preparation to structural design and construction. This new edition includes updates in all chapters and two new chapters on emerging topics that are becoming universally important: engineering of sustainable pavements and environmental mitigation in transportation projects. It also contains new examples and new figures with more informative schematics as well as helpful photographs. The text describes the significance of standards and examines traffic, drainage, concrete mixes, asphalt binders, distress and performance in concrete and asphalt pavements, and pavement maintenance and rehabilitation. It also contains a chapter on airport pavements and discusses nondestructive tests for pavement engineering using nuclear, deflection-based, electromagnetic, and seismic equipment. The authors explore key concepts and techniques for economic analysis and computing life-cycle cost, instrumentation for acquiring test data, and specialty applications of asphalt and concrete. The Second Edition includes more relevant issues and recently developed techniques and guidelines for practical problems, such as selection of pavement type, effect of vehicle tires, and use of smart sensors in rollers and software for drainage analysis. This book presents in-depth, state-of-the-art knowledge in a range of relevant topics in pavement engineering, with numerous examples and figures and comprehensive references to online resources for literature and software. It provides a good understanding of construction practices essential for new engineers and materials processing and construction needed for solving numerous problems.

Book Description
The objective of this research is to establish the technical engineering and cost analysis concepts that will enable WisDOT management to objectively evaluate the feasibility of switching construction specification philosophies for aggregate base. In order to accomplish this goal, field and laboratory testing programs were conducted on existing HMA pavements and on base layers under construction as well as comprehensive survey was conducted on highway agencies practices pertaining to base layer construction in the U.S. and Canada. This research proposed construction specifications for aggregate base course layers.

Book Description
The Minnesota Department of Transportation (Mn/DOT) began testing the dynamic cone penetrometer (DCP) in 1991, finding the DCP an effective tool in the assessment of subsurface pavement conditions and strength. Researchers conducted extensive DCP testing and research on both the Minnesota Road Research Project (Mn/ROAD) and several pilot project sites in an effort to understand its useful applications in Minnesota. Mn/DOT currently specifies two applications of DCP testing in its pavement assessment procedure. One application involves using the DCP as a quality control device during the backfill compaction of pavement edge drain trenches. The second application involves its use in quality control of granular base layer compaction. This report details these applications and includes a copy of both specifications in the appendices.

Book Description
The aircraft landing gear and its associated systems represent a compelling design challenge: simultaneously a system, a structure, and a machine, it supports the aircraft on the ground, absorbs landing and braking energy, permits maneuvering, and retracts to minimize aircraft drag. Yet, as it is not required during flight, it also represents dead weight and significant effort must be made to minimize its total mass. The Design of Aircraft Landing Gear, written by R. Kyle Schmidt, PE (B.A.Sc. - Mechanical Engineering, M.Sc. - Safety and Aircraft Accident Investigation, Chairman of the SAE A-5 Committee on Aircraft Landing Gear), is designed to guide the reader through the key principles of landing system design and to provide additional references when available. Many problems which must be confronted have already been addressed by others in the past, but the information is not known or shared, leading to the observation that there are few new problems, but many new people. The Design of Aircraft Landing Gear is intended to share much of the existing information and provide avenues for further exploration. The design of an aircraft and its associated systems, including the landing system, involves iterative loops as the impact of each modification to a system or component is evaluated against the whole. It is rare to find that the lightest possible landing gear represents the best solution for the aircraft: the lightest landing gear may require attachment structures which don't exist and which would require significant weight and compromise on the part of the airframe structure design. With those requirements and compromises in mind,The Design of Aircraft Landing Gear starts with the study of airfield compatibility, aircraft stability on the ground, the correct choice of tires, followed by discussion of brakes, wheels, and brake control systems. Various landing gear architectures are investigated together with the details of shock absorber designs. Retraction, kinematics, and mechanisms are studied as well as possible actuation approaches. Detailed information on the various hydraulic and electric services commonly found on aircraft, and system elements such as dressings, lighting, and steering are also reviewed. Detail design points, the process of analysis, and a review of the relevant requirements and regulations round out the book content. The Design of Aircraft Landing Gear is a landmark work in the industry, and a must-read for any engineer interested in updating specific skills and students preparing for an exciting career.
