  NCHRP R697 - Design Guidelines for Increasing the Lateral Resistance of Highway-Bridg
Posted by: mahyarov - 10-23-2012, 09:18 AM - Forum: Soil Investigation and Mechanics - Replies (2)

Design Guidelines for Increasing the Lateral Resistance of Highway-Bridge Pile Foundations by Improving Weak Soils

Author: Rollins, Kyle Brown, Dan | Size: 6.70 MB | Format: PDF | Quality: Original preprint | Publisher: Transportation Research Board | Year: 2011 | pages: 115 | ISBN: 9780309213417

[Image: 35012629603854390334.png]

This report presents design guidance for strengthening of soils to resist lateral forces on bridge pile foundations. Lateral loads may be produced by wave action, wind, seismic events, ship impact, or traffic. Strengthening of soil surrounding the upper portions of piles and pile groups—for example by compaction, replacement of native soil with granular material, or mixing of cement with soil—may be more cost-effective than driving additional piles and extending pile caps as ways to increase the bridge foundation's capacity to resist lateral forces associated with these loads. This report presents computational methods for assessing soil-strengthening options using finite-element analysis of single piles and pile groups and a simplified approach employing commercially available software. The analysis methodology and design guidelines will be helpful to designers responsible for bridge foundations likely to be exposed to significant lateral loads.

  NCHRP - R703 Guide for Pavement-Type Selection
Posted by: mahyarov - 10-23-2012, 09:15 AM - Forum: Traffic Engineering - No Replies

Guide for Pavement-Type Selection

Author: Hallin, J P Sadasivam, S Mallela, J Hein, D K Darter, M I Von Quintus, H L | Size: 2.97 MB | Format: PDF | Quality: Original preprint | Publisher: Transportation Research Board | Year: 2011 | pages: 78 | ISBN: 9780309213486

[Image: 60518064050401984024.png]


[Image: info.png]

This report presents a recommended "Guide for Pavement-Type Selection." The guide includes practical, logical, and transparent processes for conducting systematic evaluations of pavement alternatives and for making decisions on pavement-type selection. These processes can be used for both agency-based and contractor-based type selections and may be applied to different pavement types and structures. These processes are supplemented by examples to illustrate the application of the recommended guide for the commonly encountered scenarios of alternative bidding and design-build of operations and maintenance projects. The material contained in the report will be of immediate interest to state pavement engineers, design consultants, paving contractors, and others involved in project design and pavement-type selection.

  Proposed Specifications for LRFD Soil-Nailing Design and Construction
Posted by: mahyarov - 10-23-2012, 09:12 AM - Forum: Soil Investigation and Mechanics - No Replies

Proposed Specifications for LRFD Soil-Nailing Design and Construction

Author: Lazarte, Carlos A | Size: 6.47 MB | Format: PDF | Quality: Original preprint | Publisher: Transportation Research Board | Year: 2011 | pages: 145 | ISBN: 9780309213516

[Image: 15126204911640287025.png]


[Image: info.png]

This report contains proposed specifications for the design and construction of soil-nailed retaining structures. Despite their advantages in cut applications, these structures are not available to some state departments of transportation, due to the lack of guidance for their use in AASHTO's standard specifications based on load and resistance factor design (LRFD). This report will be of interest to geotechnical engineers and construction managers, who would like to promote a more common utilization of soil nailing.

  A Performance-Related Specification for Hot-Mixed Asphalt
Posted by: mahyarov - 10-23-2012, 07:45 AM - Forum: Traffic Engineering - No Replies

A Performance-Related Specification for Hot-Mixed Asphalt

Author: Fugro Consultants, Incorporated | Size: 11.76 MB | Format: PDF | Quality: Original preprint | Publisher: Transportation Research Board | Year: 2011 | pages: 198 | ISBN: 9780309213646

[Image: 14409563868936547367.png]


[Image: info.png]

This report provides a proposed performance-related specification (PRS) for hot-mix asphalt (HMA) in the form of the Microsoft Windows®-based Quality-Related Specification Software (QRSS). The report details the research performed and illustrates the development of the QRSS and its ability to carry out pay adjustment factor and payment computations by comparing the as-built pavement performance with that of the as-designed pavement. Thus, the report will be of immediate interest to staff of state highway agencies, materials suppliers, and paving contractors with responsibility for specification and construction of HMA pavements.

  Investigation of Short-Term Laboratory Aging of Neat and Modified Asphalt Binders
Posted by: mahyarov - 10-23-2012, 07:42 AM - Forum: Traffic Engineering - No Replies

Investigation of Short-Term Laboratory Aging of Neat and Modified Asphalt Binders

Author: Anderson, David A Bonaquist, Ramon | Size: 3.56 MB | Format: PDF | Quality: Original preprint | Publisher: Transportation Research Board | Year: 2012 | pages: 76 | ISBN: 9780309213639

[Image: info.png]

This report provides a proposed method of test for short-term laboratory aging of neat and modified asphalt binders using the Modified German Rotating Flask (MGRF) as an alternative to the Rolling Thin Film Oven Test (RTFOT, AASHTO T 240). Thus, the report will be of immediate interest to staff of state highway agencies, materials suppliers, and paving contractors with responsibility for specification and testing of asphalt binders.

  NCHRP - R711 Guidance for the Selection, Use, and Maintenance of Cable Barrier System
Posted by: mahyarov - 10-23-2012, 07:04 AM - Forum: Traffic Engineering - No Replies

Guidance for the Selection, Use, and Maintenance of Cable Barrier Systems

Author: Marzougui, Dhafer Mahadevaiah, Umashankar Tahan, Fadi Kan, Cing Dao (Steve) McGinnis, Richard Powers, Richard | Size: 35.38 MB | Format: PDF | Quality: Original preprint | Publisher: Transportation Research Board | Year: 2012 | pages: 142 | ISBN: 9780309258425

[Image: 39832426871624691291.jpg]


[Image: info.png]

This report provides guidance for the selection, use, and maintenance of cable barrier systems. While cable barrier systems have been in use for more than 70 years, their use has been on the rise and is expected to continue in the future. The increase in use of cable barrier systems has been attributed to the success rate in keeping vehicles from crossing the median, reducing roadway departures, and decreasing impact severity. Due to advancements in cable barrier system technology, installation and repair costs are lower and cable barrier use has increased in varying roadway environments. Safety studies, although limited, have shown that cable barriers help reduce those median cross-over collisions that lead to some of the most severe head-on type crashes. This document will be of particular interest to design, maintenance, traffic, and safety engineering professionals.

[Image: info.png]

This two-volume report provides a methodology for estimating the life expectancies of major types of highway system assets, in a form useful to state departments of transportation (DOTs) and others, for use in lifecycle cost analyses that support management decision making. Volume 1 is a guidebook for applying the methodology in DOT asset management policies and programs. Volume 2 describes the technical issues and data needs associated with estimating asset life expectancies and the practices used in a number of fields—such as the energy and financial industries—to make such estimates.
