INTRODUCTION :
The purpose of this workbook is to provide enough basic and practical knowledge about asphalt pavements to be able to make good decisions when roads are in need of rehabilitation, repair or maintenance. This workbook will briefly touch on technical topics such as pavement structures, asphalt mixtures, and drainage. It is important to know where pavements and mixes get their strength, and how water, if not properly controlled, can destroy a road.
The workbook covers the following subjects:
• Fundamentals of a good road
• Materials used in roadway construction
• Types and causes of pavement failures
• Rehabilitation treatments for pavements
• Inspection of asphalt pavement construction
Each of these topics is important enough to warrant a separate, full–day training course. Therefore, the workbook can only cover the most critical points. The main goal of this workbook and accompanying course is to train participants to:
• Recognize various types of pavement failures
• Know the probable causes of pavement failures
• Recognize options to repair failures
• Assure that the repairs are properly constructed
The emphasis will be on hot mix asphalt (HMA) because it is the most widely used product. However, cold mixes will also be discussed. Because HMA is not the correct treatment for all pavement problems, rehabilitation treatments such as cold in–place recycling and full depth reclamation with stabilizing agents (asphalt emulsion, foamed asphalt, and portland cement) will also be covered.
Due to the New York State Department of Transportation (NYSDOT) use of metric units, the primary units in this manual are metric. Where possible both metric and U.S. customary units are shown.
Detailed explanations of these topics can be found in the references listed in Appendix A. These publications are readily available from industry groups such as the Asphalt Institute, National Asphalt Pavement Association, and the Asphalt Recycling and Reclaiming Association. The Cornell Local Roads Program has copies of these references available for loan.

Connections are among the most essential parts in precast structures. Their performance
relates to the structural limit states, as well as to manufacture, erection and maintenance of the
structure itself. Proper design of connections is one major key to a successful prefabrication.
The literature on this matter mostly illustrates classical solutions, often well known, but an
explanation of a general design philosophy for the design of connections was necessary. In
fact, the engineer, confronted with particular problems in his daily practice, does not always
have the theoretical basis to find the most appropriate solutions.
fib Commission 6 “Prefabrication” therefore formed a Task Group – TG 6.2 – who drafted
this Guide to Good Practice with the goal of filling this gap. Its philosophy focuses on the
knowledge of the behaviour of a whole structure, of the mechanisms and paths of force
transfer within the connections and of their interaction with the structural members. Indeed,
such knowledge is the base for assessing the safety and reliability of usual types of
connections and to develop innovative design.
The Task Group has been working during several years, to collect and discuss information
and studies about the different aspects intervening in the design of structural connections for
precast concrete structures. The result is a voluminous document, with a comprehensive
survey of basic principles and design guidelines, illustrated by several examples of adequate
solutions.
Throughout these years, the Commission, chaired by the undersigned persons, supported the
activity of the Task Group with comments and discussion. However the merit for the
finalization of the work into this Guide must be acknowledged as mainly due to the
tenaciousness of its Convener, Prof. Björn Engström of Chalmers University, Sweden.

The object of this book is not teach novel techniques but to provide a handy reference to many popular techniques. All of the techniques included are elementary in the usual mathematical sense; because this is designed to be functional it does not include many abstract methods of limited applicability. This handbook has been designed to serve as both a reference book and as a complement to a text on differential equations. Each technique described is accompanied by several references; these allow each topic to be studied in more detail.
This book should act as a concise reference for the techniques that a student has learned. It is useful for the practicing engineers or scientists who solves differential equations on an occasional basis.

THE BEHAVIOR OF INVERTED PENDULUM STRUCTURES DURING EARTHQUAKES
Author: George Housner | Size: 635.35 KB | Format:PDF | Quality:Scanner | Publisher: Bulletin of the Seismological Society of America | Year: 1963 | pages: 15
During the Chilean earthquakes of May, 1960, a number of tall, slender structures survived the ground shaking whereas more stable appearing structures were severely damaged. An analysis is made of the rocking motion of structures of inverted pendulum type. It is shown that there is a scale effect which makes tall slender structures more stable against overturning than might have been expected, and, therefore, the survival of such structures during earthquakes is not surprising.

The book is an useful resource for educators and self-learners alike. It is well organized, covers single variable and multivariable calculus in depth, and is rich with applications.
The book is accompanied by other educational resources like: An online Instructor's Manual and a Student Guide.
The author has also created a series of videos to show ways in which calculus is important in our lives. The videos, which include real-life examples to illustrate the concepts, are ideal for high school students, college students, and anyone interested in learning the basics of calculus.
See the links listed below to find the aforementioned "others educational resources", videos as well as the direct link to book.
