Designed for Durability
The Marc Basnight Bridge, completed in February, carries North Carolina Highway 12 over the Oregon Inlet, an area that is one of the most dynamic and dangerous inlets on the Atlantic Coast. At 2.8 mi long,...

Advances In Geosynthetic Solutions For Sustainable Landfill Design: Geosynthetics Really Do Last!
Even though geosynthetics are now a well-established discipline within geotechnical engineering, ingenuity continues to play a significant role in projects involving their use. This is because it’s possible...

State of the Practice for Laboratory Testing of Soft Soils: It's All in the Details
As with all material testing, soils testing has undergone dramatic advances in technology because of computer automation. In the 1970s, laboratories were filled with dial gages, proving rings, mercury...

Design of the Future Mexico City Airport: Attaining Resilience in Soft Ground
The Lake Texcoco region to the east of Mexico City is famed for its deep lacustrine deposits of compressible clay, which amplify ground shaking during seismic events. The area is also gradually subsiding...

Lightweight Alternatives for Embankments on Soft Ground: A Focus on Railway Systems
Lightweight material for civil engineering application is primarily used for accelerated roadway and bridge approach construction, settlement mitigation, utility and tunnel abandonment, reduction of static...

Properties of Biochar-Amended Highway Soils: Biochar – An Eco-friendly Geomaterial
Historically, geotechnical engineers have designed or modified soils and sediments to achieve particular strength, volume change, or flow characteristics. For example, lime and fly ash have been used to...

ASCE-ASME Journal of Risk and Uncertainty in Engineering Systems, Part A: Civil Engineering
The journal will meet the needs of the researchers and engineers to address risk, disaster and failure-related challenges due to many sources and types of uncertainty in planning, design, analysis, construction,...

Rock Glue Gets the Job Done: Reducing Rockfall Hazards along the G.W. Parkway
After a large rockfall damaged the road and disrupted traffic along the George Washington Memorial Parkway in 2002, the National Park Service was looking for solutions to stabilize the slope against additional...

Borehole Geophysics: Tools to Characterize Rock Properties
Effective design and construction in rock requires characterization of the engineering properties of the rock mass, as well as any associated geological features such as joints, faults, and bedding planes....

Low-Gravity Experiments: Shear Testing Takes a Nose Dive
A major challenge to making celestial soil mechanics viable is to re-engineer the profession's toolkit to provide geotechnical solutions without the luxury of ex-situ and in-situ testing as we know them...

Appraisal of Lightweight Moorings for Deep Water
This paper outlines the potential advantages of using lightweight fiber ropes for mooring floating production platforms. The influence of tether properties on mooring system response is discussed. It is...

Journal of Transportation Engineering, Part B: Pavements

The Uselessness of Elephants in Compacting Fill
This article is based on an article that was originally published in the August 1967 Canadian Geotechnical Journal (Vol. IV, Number 3)....

Cracking the Nuclear Code: Finding an Alternative to the Nuclear Density Gauge
Two of the most basic quality control tests made in the field during soil construction are the soil’s moisture content and density. The establishment of a uniform procedure to compare the performance of...

Translating the Language of Soils: Developing a Soil Classification System for International Engineering Projects
Soil classification systems are used to help predict soil behavior and provide information to farmers, engineers, builders, agricultural extension agents, homeowners, community planners, and government...
