The purpose of the Railroad-Highway Grade Crossing Handbook – Revised Second Edition is to provide a single reference document on prevalent and best practices as well as adopted standards relative to highway-rail grade crossings. The handbook provides general information on highway-rail crossings; characteristics of the crossing environment and users; and the physical and operational improvements that can be made at highway-rail grade crossings to enhance the safety and operation of both highway and rail traffic over crossing intersections. The guidelines and alternative improvements presented in this handbook are primarily those that have proved effective and are accepted nationwide. This handbook supersedes the Railroad-Highway Grade Crossing Handbook, published in September 1986. This update includes a compendium of materials that were included in the previous version of the handbook, supplemented with new information and regulations that were available at the time of the update. Updates were drawn from the current versions of relevant legislation, policy memoranda, Federal Register notices, and regulatory actions.

The purpose of this Maintenance Manual is to provide Maintenance personnel with guidance on how to conduct a wide variety of activities performed within the Maintenance Programs. The focus is on types of equipment, materials, techniques, and other information needed to properly carry out basic maintenance activities such as patching a pothole or removing snow from a roadway. Al though this guidance does not establish absolute standards, it helps to promote uniform operating procedures and per for mance guidelines. Highway mainte nance is carried out in a dynamic environment where varying factors can lead to different solutions to maintenance problems. Maintenance and Operations personnel need flexibility to match the appropriate solutions to different conditions. The Maintenance Manual is one of many resources that are available for trained maintenance personnel to utilize in applying their profession al judgment to their daily work.

This Manual was commissioned and published by Interpave. The aim of the port pavement design process is to safeguard the pavement from failure over a predetermined period of time or number of cargo movements. There are four categories of failure associated with port pavements, viz:
Each of these categories may influence failure in one of the other three, so a complete port pavement design must address all of the issues which might lead on a particular project to one or more of these categories of failure. For example, a full port pavement design might comprise the following elements:
- Sustainable Drainage System (SUDS) design
- structural design
- surface drainage design
- surface operational characteristics
- provision of underground services
- traffic and storage management markings, signs and
structures
- interface with other facilities and structures
- selection of appropriate construction techniques
- working environmental issues
- aesthetics.
This Manual is concerned specifically with the structural design of pavements serving ports and other industries. It includes guidance on pavements designed to accord with SUDS requirements. Designers are advised to take into account all of the above issues plus others which are not listed but which might be of relevance to a specific project. Ignoring one or more component of the whole design process can lead to progressive reduction in pavement serviceability and performance so that ultimately one or more of the four categories of failure will occur.
Three sets of design calculations are included in this Manual.
Design Example 1: Reach Stacker Handling Containers
Design Example 2: Eight Wheel Straddle Carrier Handling Containers
Design Example 3: Distribution Warehouse with Dock Levellers
Also, five Overlay Design examples are included within the Overlay Design section of this Manual.

In the first, 1986, edition of this book, inverse problems in vibration were interpreted strictly: problems concerning the reconstruction of a unique, undamped vibrating system, of a specified type, from specified vibratory behaviour, particularly specified natural frequencies and/or natural mode shapes.
In this new edition the scope of the book has been widened to include topics such as isospectral systems- families of systems which all exhibit some specified behaviour; applications of the concept of Toda flow; new, non-classical approaches to inverse Sturm-Liouville problems; qualitative properties of the modes of some finite element models; damage identification.
With its emphasis on analysis, on qualitative results, rather than on computation, the book will appeal to researchers in vibration theory, matrix analysis, differential and integral equations, matrix analysis, non-destructive testing, modal analysis, vibration isolation, etc.

P185 Guidance Notes on Best Practise on Steel Bridge Construction
This publication presents a collection of separate Guidance Notes on a range of topics concerning the design and construction of structural steelwork for bridges. The fifth issue is the result of a thorough review of all the previous notes and takes account of the change to use of the Structural Eurocodes for design and the revision of many product and executions standards associated with that change. It complements the publication Steel Bridge Group: Model Project Specification

P382 Steel Bridge Group - Model Project Specification
This publication provides a set of clauses, to be used in bridge project specifications, that responds to the options and alternatives allowed in BS EN 1090-2, the execution standard for steelwork designed to Eurocode 3. The clauses are arranged under the headings in BS EN 1090-2 and for each clause a commentary is given, explaining the context of or background to the clause. The document has been prepared by the Steel Bridge Group and is intended to achieve the same quality and reliability as has been achieved with BS 5400-6. (A separate document is available, in Word format, of the clauses alone, without commentary, to facilitate use in project documents.)

Manual for the Design of Steelwork Building Structures to Eurocode 3 October 2010
Published by: The Institution of Structural Engineers
First published: 2010
ISBN: 9781906335168
"This Manual is intended to provide guidance on the design of many common steel building frames and to show how the provisions of BS EN 1993-1-1: 2005, BS EN 1993-1-8: 2005 and BS EN 1993-1-10: 2005 can be selected for that purpose. Steel buildings frequently include composite floors and the Manual also covers some aspects of BS EN 1994-1-1: 2004. Certain limitations have been introduced to simplify the design process and to select from the comprehensive provisions of EC3 in order to aid the process of familiarisation. Much useful advice contained within the 2008 ‘grey’ book Manual for the design of steelwork building structures has been retained and will therefore be familiar to many users of this new Manual. Chapter headings appear similar to the old ‘grey’ book but opportunity has been taken to rationalise and reorder various sections"

EMERGING APPLICATIONS OF HIGH PERFORMANCE STEEL AND ULTRASOUND IMPACT TREATMENT FOR IMPROVED FATIGUE LIFE OF STEEL BRIDGES
Abstract ; Statnikov E. S.2; and Tehini L.3
With the advent of high performance materials, emerging advanced technologies and emphasis on the Federal Highway Administration’s (FHWA) Strategic Goals to mitigate congestion during construction as well as during the service life of a structure, the national perspective in the highway industry is changing towards rapid construction of highways and bridges; as well as to the deployment of maintenance techniques that can be performed quickly, economically, and effectively to achieve long lasting structures to safely transport people and goods.
This paper highlights recent advances in High Performance Steels (HPS) and maintenance technique employing Ultrasonic Impact Treatment (UIT) for steel bridges. These bridges will last longer, resist corrosion and fatigue cracking, and can be maintained efficiently and economically compared to those built and maintained in a traditional manner using conventional bridge steels. This material (steel) development effort has led to high strength 50-100 ksi (345 to 690 MPa yield strength), improved weldability, high toughness, and improved weathering (atmospheric corrosion resistant). Currently, high performance steel grades: HPS 50W, HPS 70W and HPS 100W are available. For the reasons explained above, this paper will address (a) Construction of New Structures Using High Performance Steels (HPS) and, (b) Maintenance of Structures Using Ultrasonic Impact Treatment (UIT).
