As I See It: Why Not Use Geosynthetics?
Lessons Learned from Geo-Legends: Kenneth H. Stokoe, PhD, PE, D.GE, NAE, M.ASCE
Geotextile Tube Dewatering
Geotextile tubes are made of high-strength, permeable geotextile that, when filled with a slurry, allow water to drain from the tubes while retaining the solids. They can be prefabricated...
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...
Very Long-Term Care of Mechanically Stabilized Earth Berms: Limiting the Liability of Future Stakeholders
Since their development over 50 years ago, civil engineering applications of mechanically stabilized earth (MSE) berms have significantly increased. When used as a component of an asset...
Geosynthetic Materials Help Build Optimized Infrastructure
In recent years, the world has begun to realize the negative impacts that limited infrastructure can have on economic growth and the well-being of humankind. Our infrastructure challenges...
Long-Term Performance Monitoring of a Hillside Retaining Wall
To accommodate expansion of the West Point Treatment Plant in Seattle, WA, a 3,000-ft-long soldier pile, tieback-anchored retaining wall was constructed from May 1991 to May 1992. An oblique...
The Truth about PLI
Look Who's a D.GE: Dan A. Brown, PhD, PE, D.GE, M.ASCE
January-February Article Right on the Mark
Introduction
Many institutions and private industry organizations have prepared guidance documents with the latest scientific and engineering information on proper design, installation, maintenance,...
Design Considerations Common To All Permeable Pavements
Impervious cover in watersheds without controls result in increased stormwater runoff and decreased groundwater recharge in response to rainfall events. This increased runoff can be the...
Porous Asphalt and Permeable Friction Course Overlays
Porous asphalt typically consists of conventional warm mix asphalt (WMA) or hot mix asphalt (HMA) with significantly reduced fines resulting in an open-graded mixture that allows water...
Pervious Concrete
Pervious concrete consists of a hydraulic cementitious binding system combined with an open-graded aggregate to produce a rigid pavement with typically 15% to 25% interconnected void space....
Permeable Interlocking Concrete Pavement (PICP)
Permeable interlocking concrete pavement (PICP) consists of (impervious) manufactured concrete units that form permeable voids and joints, when assembled into a laying pattern. The openings...
Grid Pavement
Open grid pavements consist of concrete or plastic units with large surface openings filled with a permeable joint material, typically small aggregate (ASTM No. 8 or No. 89), sand, or...
Alternative Technologies
In recent years, new permeable pavement product variations have entered the market. This chapter describes general characteristics for several emerging products. The following types of...
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,...
