Slope vulnerability is assessed in M nDOT Slope Vulnerability Assessments Phase 2 , a report from the Minnesota Department of Transportation. This report outlines the methods and results of this project including the new landforms, geomorphic processes, and causative factors influencing slope failures in this part of the state. It is a continuation of the first phase of the project.

The risk of slope failure along state highways around Minnesota is analyzed in MnDOT Slope Vulnerability Assessments Phase 2 , a report from the Minnesota Department of Transportation. Minnesota’s climate, geomorphology, and steep terrain along rivers has the potential to increase the incidence of slope failures such as rockfalls and landslides. This report is a continuation of the Phase 1 report.

TRB’s Technical Activities Division has released Transportation Research Circular E-C248: 12th International Conference on Low-Volume Roads, highlighting topics including road surfaces, geotechnology, cold regions and climate change, pavement management, planning and economics, unpaved roads management, geosynthetics in low-volume roads, drainage and stream crossings, climate change resiliency...

Installation and removal of sheet pile walls are investigated in Effect of Proximity of Sheet Pile Walls on the Apparent Capacity of Driven Displacement Piles, Phase 2 , a report from the Florida Department of Transportation. Phase 1 of this project developed a methodology for assessing the proximity of sheet pile walls on the load capacity of piles driven into granular materials. This phase ex...

The World Road Association (PIARC) has released a report that outlines current rules and practices for earthworks management. This manual includes information about design of materials and structures, executions and controls, and environmental aspects, including those related to climate change. The report is available for no fee after logging onto the site.

The Florida Department of Transportation has released a report that investigates Florida rock index properties by establishing correlations from rock index properties to conventional strength results. The goals of this report are to develop strength envelopes for both compression and extension loading and to develop stress-strain and volumetric strain models for Florida carbonate rock.

TRB’s National Cooperative Highway Research Program (NCHRP) Synthesis 532: Seismic Design of Non-Conventional Bridges documents seismic design approaches and criteria used for “non-conventional” bridges, such as long-span cable-supported bridges, bridges with truss tower substructures, and arch bridges. Design of conventional bridges for seismic demands in the United States is based on one of t...

The Minnesota Department of Transportation has released a report that validates the Trimble MX7 system for use with intelligent compaction and paver mounted thermal profiling technologies. The Trimble MX7 is a mobile imaging system with geospatial capabilities. This report also identifies the Trimble MX7’s capability to collect other asset information along the roadway.

TRL Limited has released a report that describes a method to identify and forecast periods of time when the debris flow hazard is greater and landslide risk increases. Rainfall-induced debris flows, a form of landslide, are common in Scotland. The goal of this report is to rank the hazards posed by debris flows.

TRL Limited has released a report that describes a project to capture panoramic imagery over a two-year period at a site that is highly susceptible to rainfall-induced debris flow. The goal of this report is to determine the hazard from boulders at the site.
