This circular explores the state of the practice and representative applications on the use of inclinometer systems for measuring ground deformation and performance of geotechnical design elements on transportation projects. The report examines inclinometer components and installation details, and includes information on planning inclinometer installation, acquiring and displaying data, and interpreting test results.

Geophysical Methods Commonly Employed for Geotechnical Site Characterization
Author: Anderson, Neil L | Size: 1.35 MB | Format:PDF | Quality:Original preprint | Publisher: Transportation Research Board | Year: 2008 | pages: 44
This circular offers an overview of 12 geotechnical geophysical methods that are commonly applied to transportation projects. Geotechnical geophysics is the application of geophysics to geotechnical engineering problems; such investigations normally extend to total depths of less than 300 ft. Geotechnical geophysical surveys are performed on the ground surface, within boreholes and water, and from the air. Using illustrations and brief examples, commonly employed geotechnical geophysical methods are described. Through summary tables and brief discussions, common applications of engineering geophysics are presented. Chapters are devoted to the selection of appropriate geophysical methods and geophysical contractors, respectively. Use of geophysics by transportation agencies is reviewed through a summary of NCHRP Synthesis 357: "Use of Geophysics for Transportation Projects" (Sirles, 2006). A detailed description of applications of geophysical methods to highway-related problems may be found at www.cflhd.gov/agm/index.htm.

This circular is designed to help explain the basic concepts and definitions of dynamic traffic assignment (DTA) models and addresses the application, selection, planning, and execution of a DTA model. The report also describes the general DTA modeling procedure and modeling issues that may concern a model user.

This workshop’s mission was to inform the pavement engineering community on the completed and on-going efforts related to assessing the sensitivity of the Mechanistic– Empirical Pavement Design Guide (MEPDG). Specifically, the workshop was concerned with those parameters that had an impact on flexible pavement analysis and design. Many transportation agencies have been involved in various studies to look at particular parts of the MEPDG, but much of this work had not been compiled into a single document. As such, a workshop was proposed by the Transportation Research Board (TRB) Flexible Pavement Design Committee (AFD60) and approved by TRB to look at the flexible pavement sensitivity analysis in the MEPDG. Once accepted, a planning team was established to develop the workshop by collecting and disseminating the work done by transportation agencies. The workshop planning team had two primary goals: (1) Take a snapshot of the current implementation status of transportation agencies through a questionnaire and reporting on workshops hosted by the Federal Highway Administration and (2) Invite transportation agencies based on their responses to the questionnaire to present on a specific subject or overall research implementation effort. Additionally, the planning team wanted to capture and present current National Cooperative Highway Research Program research related to flexible pavement analysis and performance. Workshop Session 143, held in January 2010, met these goals by providing presentations on various efforts related to understanding the sensitivity of flexible pavement performance using the MEPDG inputs.

The Superpave Mix Design System: Anatomy of a Research Program
Author: McDaniel, Rebecca S Leahy, Rita B Huber, Gerald A Moulthrop, James S Ferragut, Ted | Size: 2.62 MB | Format:PDF | Quality:Original preprint | Publisher: Transportation Research Board | Year: 2011 | pages: 185 | ISBN: -
The asphalt research program conducted as part of the Strategic Highway Research Program was the most focused asphalt research program ever. Intense research activity over a nominal five-year period at a cost of $50 million dollars led to sweeping changes in how asphalt materials are specified, tested and designed. The products of this research, known collectively as the Superpave mix design system or simply Superpave, are used across the U.S. and internationally. This report describes how such a large-scale research effort was conceived, funded, and managed. It outlines the research and implementation efforts that brought the products into routine use. Lastly, it summarizes some of the key lessons learned in the process of conducting such a large-scale program. The findings outlined in this report were garnered through interviews with over 70 people who were involved in the research and implementation efforts as well as reviewing reports, letters, diaries, meeting minutes and other documents.

Seismic Design of Geosynthetic-Reinforced Soil Bridge Abutments with Modular Block Facing
Author: Helwany, Sam Wu, Jonathan Meinholz, Philip | Size: 28.47 MB | Format:PDF | Quality:Original preprint | Publisher: Transportation Research Board | Year: 2012 | pages: 260 | ISBN: -
A geosynthetic-reinforced soil (GRS) mass is formed by placing closely-spaced layers of polymeric geosynthetic reinforcement in a soil mass during soil placement. The reinforcement in a GRS mass serves primarily to improve engineering properties of soil. The concept of GRS has been used successfully over the past few decades in many transportation facilities, including retaining walls, embankments, roadways, and steepened slopes. Tests and in-service installations have shown that GRS systems, particularly GRS walls with modular-block facing, are structurally sound, easy and fast to construct, and low cost compared to other designs. Interest in using GRS design for bridge abutments and approaches, in particular, has grown but a lack of rational and reliable design and construction guidelines for such structures has impeded more widespread adoption. NCHRP Report 556, "Design and Construction Guidelines for Geosynthetic-Reinforced Soil Bridge Abutments with a Flexible Facing," was produced as a first step effort toward developing such guidelines. The research described in that report addressed static loading conditions only. NCHRP Project 12-59(01), the subject of this report, was undertaken to develop design and construction guidelines for applications in seismically active regions. The research described here focused on single-span, simply-supported bridges subjected to seismic forces. Current seismic design methods for reinforced soil retaining walls – both pseudo-static methods and displacement methods – have been developed for situations where the self-weight of the soil is the predominant load. For a GRS bridge abutment, however, the abutment’s top surface is intended to provide a foundation of the bridge superstructure. The GRS abutment will be expected not only to maintain its stability as a soil mass but also to bear the additional large sustained and seismic loads associated with the bridge superstructure. The objective of this research was to extend the earlier research reported in NCHRP Report 556 to consider seismic loading conditions and thereby provide a more comprehensive basis for developing rational guidelines for design and construction of GRS abutments and approaches with modular-block facing.
