Practical Aspects Of Routine Geotechnical Site Investigations — They Should Be Anything But Boring!
It’s likely that on any given day there are hundreds of geotechnical site investigations in progress in North America alone. While many of these investigations are carried out in support of large projects,...

Moving Down the Road of Progress: Geosynthetics Subdue Failures on Expansive Clays and Frost-susceptible Soils
Using geosynthetics in roadway projects has provided sustainable alternatives for reconstruction and maintenance and now represents a significant portion of the total geosynthetics market. Geosynthetics...

A Foundation Engineering Trip Down the Mississippi: Foundations for Mississippi River Bridges from Minnesota to Louisiana
Huckleberry Finn had his adventure, but for those interested in foundation engineering, this article will float you down the Mississippi River on your own encounter with the many bridges...

Evaluating Bridges With Unknown Foundations for Susceptibility to Scour: North Carolina Applies Risk-Based Guidelines to Over 3,750 Bridges
Scour occurs when flowing water removes erodible material such as sand and rock. For bridges over water, scour affects the stability of pier and abutment foundations and contributes to...

National Usage of Geosynthetic-Reinforced Soil to Support Bridges
The Geosynthetic-Reinforced Soil Integrated Bridge System (GRS IBS) was developed by the Federal Highway Administration (FHWA) almost 20 years ago to help meet the demand for the next...

Achieving Success and Avoiding Failures with Permeable Pavements
This chapter provides experienced-based recommendations on how to achieve success with permeable pavements. This information is based on an informational survey completed by designers,...

Loading, Geometry, and Analysis
This Standard applies to latticed steel transmission structures. These structures shall be either self-supporting or guyed. They consist of hot-rolled or cold-formed prismatic members...

Spread Footings Revisited: Geotechnical Advances Lead to Expanded Use for Bridge Abutments
The Minnesota Department of Transportation (MnDOT) has historically used steel shell piles to support highway bridge structures, probably due to a blend of familiarity and efficiency among...

Dynamic Shearing Properties Of Compacted Clay
A series of 116 Q-type triaxial compression tests was performed using specimens of Goose Lake clay compacted at water contents ranging from 9 percent dry of optimum to 3 percent on the...

Failure of a Large Circular Excavation
A circular excavation, 117 feet (36 m) in diameter by 90 feet (27 m) deep, was designed by an experienced engineering firm and construction was performed by an experienced contractor....

Failure of a Twenty-Foot High Retaining Wall
A cantilever retaining wall, designed in apparent accord with provisions in a civil engineering handbook, failed soon after construction. Analyses of the causes of the failure are presented....

Condition Indices, Performance Measures, and Managing Performance Data for Geotechnical Asset Management – Don't Get Buried!
Why don't transportation agency assets like pavements, bridges, and earthwork have a Check Engine light? Why can't you simply pull up the complete history and life cycle plan for them?...

Risk-based Methods for Geotechnical Features in Transportation Asset Management
The purpose of asset management is to meet life cycle performance goals through the management of assets in the most cost-effective manner. In developing risk-based, asset management plans...
