The purpose of this manual is to provide clear and helpful information for maintaining gravel roads. Very little technical help is available to small agencies that are responsible for managing these roads. Gravel road maintenance has traditionally been "more of an art than a science" and very few formal standards exist. This manual contains guidelines to help answer the questions that arise concerning gravel road maintenance such as: What is enough surface crown? What is too much? What causes corrugation? The information is as nontechnical as possible without sacrificing clear guidelines and instructions on how to do the job right.
Shell has been at the forefront of bitumen technology for over 90 years, and continues to play a leading role in global bitumen research and development. The Shell Bitumen Handbook is an authoritative source of information on bitumen use in road pavements around the world.
For more than 70 years, "MS-4" has served the asphalt industry as its primary reference manual. This new, expanded edition showcases the advances in asphalt technology, covering such topics as superpave courses, asphalt binder, quality control, and rehabilitation of concrete pavements with HMA.
This fully revised fourth edition of Max Lay's well-established reference work covers all aspects of the technology of roads and road transport, and urban and rural road technology. It forms a comprehensive but accessible reference for all professionals and students interested in roads, road transport and the wide range of disciplines involved with roads. International in scope, it begins with the preliminary construction procedures; from road planning policies and design considerations to the selection of materials and the building of roads and bridges. It then explores road operating environments that include driver behaviour, traffic flow, lighting and maintenance, and assesses the cost, economics, transport implications and environmental impact of road use. It draws on Max Lay's unparalleled consulting and operational experience in the financing, planning, design, construction, operation and management of roads in various countries. It forms an indispensable resource for transport planning, engineering, operations and economics.

The comprehensive guide to construction tolerances, newly revised and updated How much may a steel frame be out of plumb? What are the expected variations of a precast concrete panel? What is required to successfully detail finish materials on masonry? Updating and expanding on its popular first edition, the Handbook of Construction Tolerances, Second Edition remains the only comprehensive reference to the thousands of industry standard tolerances for the manufacture, fabrication, and installation of construction materials and components-- including all-important accumulated dimensional variations. Covering new materials and techniques developed since the book was first published, the Second Edition of this easy-to-use reference features: * More than 100 drawings illustrating the tolerance concepts * New sections on measuring compliance with tolerance standards; right-of-way construction; autoclaved aerated concrete; tilt-up concrete panels; interior stone wall cladding; structural insulated panels; decorative architectural glass; laminated architectural flat glass and bent glass * New guidelines on how to incorporate tolerance requirements in drawings and specifications * New information on how to apply tolerance information during contract administration With the Handbook, architects, engineers, contractors, interior designers, lawyers, and others involved in the construction industry will be armed with the information they need to design and detail more accurately, write better specifications, establish normal practice and standards of care, supervise construction, settle worksite disputes, and save time and money at every stage of building.
"This new edition reflects many of the very significant advances which have taken place in the period since the last edition was published. I am confident that you will feel that this is a worthy addition to your asphalt book shelf." Robert Hunter This respected Handbook has earned its reputation as the authoritative source of information on bitumens used in road pavements and other surfacing applications. This new edition has been up-dated to ensure The Shell Bitumen Handbook retains its excellent reputation. This comprehensive Handbook covers every aspect of bitumen, from its manufacture, storage and handling to specifications and quality along with a whole chapter on bitumen emulsions. The mechanical testing and physical properties of bitumen, its structure and rheology, properties such as durability and adhesion, and the influence of these properties on performance in practice are all set out in individual chapters. A further chapter is devoted to the practice of enhancing the performance of bitumen's by the addition of modifiers. Considerable attention is given to the different aspects of asphalts, detailing types of mixture, their manufacture and testing, mechanical properties, transport, laying and compaction and mixture design. This excellent reference also devotes chapters to the important topics of analytical design of flexible pavements and the technology of surface dressing. Since the last edition, there have been significant strides in a number of key areas of asphalt technology. These include the development of new mixtures, an improved understanding of the mechanisms by which pavements fail and the availability of high-performance bitumens. The Handbook has been fully revised to reflect these advances, as well as updating the standard procedures and methods which are necessary nowadays for those involved in using asphalts in an environment of ever-more demanding specifications. Compiled by the Shell Bitumen European Technical Team The Shell Bitumen Handbook is intended to be of daily use to civil engineers in pavement construction and maintenance, and also to students and researchers.
