Salvaged Sand
Waste foundry sand has been rediscovered as a road construction material now that environmental concerns about its use have been laid to rest. Certain types of waste foundry sand, a by-product...
Wonderwall
A Superfund site near Seattle was surrounded by a 2,200-ft-long soil-bentonite wall to keep contaminants from entering nearby water sources. An earlier remediation effort had failed to...
Rerouting Boston's Utilities
During construction of the Central Artery/Tunnel project in downtown Boston, engineers had to move utility lines over and under both new and existing infrastructure and maintain utility...
Chemical Grouting
Technical Engineering and Design Guide, as adapted from U.S. Army Corps of Engineers, No. 24. This manual provides information and guidance for the...
Evaluation of the Tensar ARESTM Retaining Wall System
Prepared by the Highway Innovative Technology Evaluation Center (HITEC), a CERF Service Center. This report evaluates the ARES Retaining Wall System,...
Journal of Composites for Construction
The Journal of Composites for Construction publishes original research papers, review papers, and case studies dealing with the use of fiber-reinforced composite materials in construction. Of special interest...
Catching Up on Composites
Until recently, Japan and Germany were way ahead of the U.S. in composite material technology for construction. Lighter, stronger and possibly more durable than conventional materials...
Lining the Line
Having succeeded in achieving dry stations and tunnels in mined construction, flexible waterproofing membranes are now being used to waterproof cut-and-cover subway stations and old, leaking...
Fracturing for In-situ Bioremediation (Available only in
A pilot-scale evaluation of an integrated pneumatic fracturing and bioremediation system demonstrated the enhanced removal of BTX from a gasoline-contaminated, low-permeability soil formation....
Asphalt Update
Of the $150 million spent in the five-year Strategic Highway Research Program (SHRP), $50 million went to research to improve the durability and cost-effectiveness of asphalt pavements--on...
Cable Corrosion in Bridges and Other Structures:
Causes and Solutions
This book provides the reader with basic facts concerning cable corrosion and means to avoid or rehabilitate corrosion damage. Corrosion problems associated with cable-supported structures...
Dynamic Optimal Groundwater Remediation by Granular Activated Carbon
Objective functions to describe the operating and capital costs of GAC treatment are incorporated into a control theory model for optimal pump-and-treat groundwater remediation design....
An Update on Surface Renewal Estimation of Evapotranspiration
The surface renewal (SR) method for estimating sensible heat flux density (H) has been shown to give good estimates of evapotranspiratiou (ET) when used in an energy balance equation with...
Permeability of Clay Liners with Contaminants
Clays are increasingly used as liners for waste disposal facilities. Chemical compatibility studies with hydraulic conductivity tests must be performed to determine the effect of the waste...
Rational Design and Operation of Packed Bed Adsorption Reactors
Design of packed bed adsorption reactors is based presently upon the parameter empty bed contact time (EBCT), a fallacious concept. The column wave front behavior, instead, should be the...
Comparative Simulation of Oil Weathering
Oil spills in the aquatic environment, an unfortunately more and more common occurrence, cause contamination effects which negatively impact water quality, health of ecosystems and water...
Comparison of Methods for Sizing Secondary Treatment Filters for Wastewater
The trickling filter process in which a bacterial biomass is allowed to grow attached to a filter medium of rock or plastic is effectively used for removal of organic materials in domestic...
Rehabilitating Arctic Tundra in Alaska
During the past 25 years, there has been significant progress in tundra rehabilitation. Initially, agronomic practices requiring large quantities of grass seed and fertilizer were believed...
