Innovations in Geosynthetic Rolled Erosion Control Products: From Forests to Fibers
Over the last 50 years, many different types of geosynthetic rolled erosion control products (RECPs) have emerged, ranging from different structure types to different fiber types. Natural-fiber...
Becoming Greener with Green Sand: An Iron Castings Company Devises an Environmentally Friendly Liner System Reusing Foundry Byproduct
Metalcasting is one of the oldest methods of recycling�humans have a few millennia worth of experience with the technique�but today's industry still battles public preconceptions...
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...
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...
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...
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...
