TRB's National Cooperative Highway Research Program (NCHRP) Synthesis 519: The Renewal of Stormwater Systems Using Trenchless Technologies summarizes technologies used for the renewal of stormwater systems, including new, emerging, and underutilized trenchless methods, and identifies future research needs. Both trenchless replacement and trenchless renewal methods can reduce negative impacts as...

TRB's Transportation Research Record: Journal of the Transportation Research Board has released more than 200 papers from the 2018 TRB Annual Meeting. Enhancements to the journal include:  Articles published much closer to final acceptance A new user interface for the journal Article-level metrics  Full-text HTML to enhance discovery of the research Interactive proof markup for author...

The Center for Transportation Research at the University of Texas at Austin has released a report that evaluates soil-geosynthetic interaction under small displacements. The goal of this research is to implement an analytical model and testing procedure for selection of geosynthetic materials for base-stabilization of roadways subjected to environmental loads.

The U.S. Federal Highway Administration has released a report that evaluates the Geosynthetic Reinforced Soil-Integrated Bridge System program (GRS-IBS). This evaluation focuses on research topic selection, early research development, and deployers’ decisions to adopt GRS-IBS.

To keep pace with accelerating rate of research distribution, the Transportation Research Record: Journal of the Transportation Research Board is now publishing articles as soon as they are finalized. The latest papers to be published are as follows: Use of a Laser Diffractometer to Obtain the Particle Size Distribution of Fine-Grained Soils Interstate Speed Profiles Conditioning and Testing Pr...

TR Circular E-C230: Culverts and Soil–Structure Interaction: Fifty Years of Change and a Twenty-Year Projection summarizes the presentations from the TRB 93rd Annual Meeting on January 14, 2014 in Washington, D.C. In the past 40 to 50 years have seen significant changes in the pipe industry in terms of materials used, structure sizes, shapes, and joint capabilities. Design methodologies ha...

The Minnesota Department of Transportation has released a report that analyzes the areas in Minnesota susceptible to slope failure using state-wide available data. The objective of this research was to determine whether it would be possible to provide slope-failure susceptibility mapping that could be used by local road and highway officials to understand where slope failure may occur.

The Louisiana Department of Transportation and Development has released a report that identifies how to apply available soil data, such as spatial distribution of soil types and soil characteristics, toward creating a GIS-based map to identify corrosion zones in coastal Louisiana. Many transportation agencies allow metal culverts as options for cross drains under and along roads and highways, w...

The Illinois Center for Transportation at the University of Illinois at Urbana-Champaign has released a report that develops Illinois-specific design procedures for drilled shafts found in weak shale or rock. This research explores ways to develop safer deep-foundation design at a reduced cost.

The full edition of the July–August 2017  TR News  magazine is now available.  Moving research into practice is the theme of feature articles in this edition. Authors describe today’s successes, present a systematic approach that has proved effective at a state department of transportation, describe federal programs encouraging innovations at the state level, discuss initiatives ...
