AASHTO Guide Specifications for Highway Construction

AASHTO Guide Specifications for Highway Construction

AASHTO Guide Specifications for Highway Construction 9th Edition The  Guide Specifications for Highway Construction provide guidance for the development of highway contract specifications and are intended to complement the LRFD specifications for major structures and bridges.

This ninth edition AASHTO Guide Specifications for Highway Construction includes several new sections—Sections 312 through 315 address additional base course options; Sections 716 through 718 address materials requirements for aluminum, timber, and ground anchors; and Appendixes A and B provide sample technical provisions and considerations for use with innovative contracting methods and pavement ride quality measurement.

This AASHTO Guide Specifications for Highway Construction update of the 1998 edition expands the number of cross-references and provides uniformity of nomenclature, materials, construction requirements, and methods of measurement and payment.

This is the ninth edition of the AASHTO Guide Specifications for Highway Construction. These specifications have been developed by the AASHTO Subcommittee on Construction and are intended to complement the specifications for major structures and bridges, which are covered by the AASHTO LRFD Bridge Construction Specifications.

This edition includes four significant changes to these guide specifications. First, in order to reinforce and clarify the meanings of terms for readers, uniform terminology is used consistently throughout the specifications. Secondly, elimination of redundant language results in the deletion of some sections and an increased number of cross-references among the remaining sections. Also, the AASHTO and ASTM references within the guide specifications have been updated.

Finally, this AASHTO Guide Specifications for Highway Construction includes several new sections—Sections 312 through 315 address additional base course options; Sections 716 through 718 address materials requirements for aluminum, timber, and ground anchors; and Appendixes A and B provide sample technical provisions and considerations for use with innovative contracting methods and pavement ride quality measurement.

The many differences in climate, geology, geography, customs, statutes, and regulations make a national construction specification practically impossible. However, to provide for easier cross referencing from state to state or with other agencies, this guide provides uniformity of nomenclature, format, methods of measurement, basis of payment, and method of tests. The guide specifications provide the specification writer with information and topics to be covered and expounded on in a detailed project construction specification.

The guide specifications divisions are subdivided into Description, Materials, Construction Requirements, Method of Measurement, and Basis of Payment. Items shown in brackets, such as [50], throughout the guide specifications are suggested values and should be changed, when necessary, to meet the requirements of the various agencies or project conditions.

AASHTO Highway Drainage Guidelines, Foreword

The Highway Subcommittee on Design, as part of its charge, prepares and keeps current publications pertaining to principles, methods, and procedures of roadway design, including practices to protect and to enhance the quality of the environment. As the subject of highway drainage is important to many disciplines and many phases of highway engineering, the Subcommittee requested and received approval from the Standing Committee on Highways to establish a task force to prepare needed publications on the subject of highway drainage.

Consequently, the Task Force on Hydrology and Hydraulics was established and first met in February 1970, developed a statement of purpose, and outlined a program of activity. The purpose of the Task Force is to assist the Subcommittee in developing guidelines and in formulating policy for highway disciplines, giving due consideration to safety and the environment.

AASHTO Highway Drainage Guidelines Pursuant to this purpose, the Task Force on Hydrology and Hydraulics began the preparation of guidelines covering topics on major areas of highway hydraulic design. To the extent practicable, each Guideline is a stand-alone volume, but reference to other guidelines in the series is utilized to avoid unnecessary repetition. Since these Guidelines are intended to provide an overview, discussion, and design philosophy for each of the covered topics, technical information is kept to a minimum by making reference to appropriate publications and to the AASHTO Model Drainage Manual which contains recommended design policy, criteria, procedures, aids and example problems.

AASHTO Guide for Vehicle Weights and Dimensions

AASHTO Guide for Vehicle Weights and Dimensions

AASHTO Guide for Vehicle Weights and Dimensions 4th edition Provides information for states and for commercial carriers that can be used in connection with vehicle size and weight issues and permit practices directed towards improving safety, managing highway and bridge infrastructure, and streamlining regulatory processes.

AASHTO Guide for Vehicle Weights and Dimensions Contains definitions of commonly-used terms, descriptions of vehicles in regular operation, dimension and weight limits, and an overview of the permitting process for overweight, oversize vehicles. The Guide also provides an explanation of the rules and processes related to the movement of military vehicles.

Foreword AASHTO Guide for Vehicle Weights and Dimensions
The American Association of State Highway and Transportation Officials (AASHTO) has a unique leadership role in developing transportation policy, direction, and information for member states and the nation. In the area of vehicle weights and dimensions, AASHTO has articulated policy and recommendations since 1932.

This AASHTO Guide for Vehicle Weights and Dimensions represents part of AASHTO’s continuing efforts to provide leadership and guidance in the vital areas of vehicle weights and dimensions. In developing this updated Guide, the Subcommittee on Highway Transport considered advice, information, and input from all States, other AASHTO committees and members, FHWA, commercial carriers, and their representative groups, the Department of Defense, and other interested parties. It replaces the previous Guide published in 1991.

The primary purposes of this AASHTO Guide for Vehicle Weights and Dimensions are to:

• Provide a baseline of common terminology.
• Promote common permitting practices for overdimension/overweight operations.
• Promote improved transportation safety.
• Promote efficiency and productivity for government and industry.
• Provide necessary protection of the public infrastructure investment.
• Promote uniformity in regulation and process wherever possible while providing information and guidance to States, the military, and the private sector.
• Formalize operational procedures with the Department of Defense.

This AASHTO Guide for Vehicle Weights and Dimensions is focused on providing information and guidance for States as they manage their transportation systems and for commercial carriers and others as they utilize highway transport to meet the needs of shippers and the economy. It is recognized that a continued Federal role is necessary to provide a national view, facilitate interstate commerce, and work with States and interested parties to balance the often competing needs of shippers and carriers and other highway users, while protecting the vast public infrastructure investment and promoting improved safety.
