Electrochemical Chloride Extraction: Influence of Concrete Surface on Treatment
FHWA-RD-02-107
This report reveals that electrochemical chloride extraction
is capable of removing, in a single application, a significant portion of the chloride ions from a reinforced concrete
structure. Prior research has shown that the quantity of chloride ions removed
depends on numerous factors, including quantity and spacing of reinforcing
steel, applied voltage, and initial chloride concentration. In addition, investigations into
chloride binding and competition between other ions as current carriers have helped clarify the probable mechanisms
responsible for decreases in current efficiency over time during chloride removal.

Extrapolation of Pile Capacity From Non-Failed Load Tests
FHWA-RD-99-170
This report analyzes load testing. Load testing a static
pile to failure is the ultimate way to examine the capacity and integrity of
deep foundations. Since the procedure is expensive and time-consuming, it is
often substituted by the application of a load to a certain factor (most often
two) times the contemplated design load. This method is not preferred because
only a proof test is carried out, while the ultimate capacity and actual factor
of safety remains unknown. Therefore, researchers need to find an easier,
accurate way to reliably estimate the ultimate bearing pile capacity for
non-failed load tests.

supplemented by tests conducted during this study, led to improved concepts and
quantification of airflow dynamics for depressed sites.

Modification of Highway Air Pollution Models for Complex Site Geometries, Volume II: Wind Tunnel Test Program
FHWA-RD-02-037
This report is Volume II of a two-volume study to increase
the scope and clarity of air pollution models for depressed highway and street
canyon sites. The report presents the atmospheric wind tunnel program conducted
to increase the database and improve physical concepts of pertinent movement
and mixing of air and its contaminants. Wind tunnel measurements are less
costly than field measurements and are sensitive to controlled input variables.

Performance Test for Geosynthetic-Reinforced Soil Including Effects of Preloading
FHWA-RD-01-018
This report presents a study undertaken to investigate the
behavior of geosynthetic-reinforced soil (GRS) masses under various loading conditions and to develop a simplified
analytical model to predict deformation characteristics of a generic GRS mass.
Significant emphasis was placed on the effects of preloading. To conduct this
study, a revised laboratory test, known as the soil-geosynthetic performance
test, was developed.

Portable Instrumentation for Real-Time Measurement of Scour at Bridges
FHWA-RD-99-085
This report analyzes a portable scour-measuring system
developed to meet the requirements of three different applications: bridge
inspections, limited-detail data collection, and detailed data collection.
Commercially available instruments were evaluated for use in measuring scour at
bridges during floods. The systems developed consist primarily of commercially
available instruments, which were modified and interfaced to achieve the
required functionality.

Safety and Health on Bridge Repair, Renovation, and Demolition Projects
FHWA-RD-98-180
This report is a reference guide for bridge contractors to
use in designing and implementing a safety and health program. It is not a
"fill-in-the-blanks" document for contractors to use as a means to
claim that a safety and health program is in effect. Instead, it guides
contractors through the elements and issues that must be considered in
establishing a safety and health program.

Seismic Vulnerability of New Highway Construction, Executive Summary
FHWA-RD-99-098
This executive summary provides an overview of the results
from a Federal Highway Administration seismic research program that performed a series of special studies
addressing the seismic vulnerability of new highway structures. The studies
developed technical information that could form the basis of future
specifications for the seismic design of bridges.

South Dakota Culvert Inlet Design Coefficients
FHWA-RD-01-076
This report summarizes model testing performed on culvert
shapes to develop design coefficients for both inlet and outlet control. The
cast-in-place culverts feature 30-degree flared wingwalls and a beveled top
edge. The precast culverts have a 0-degree flare and a constant
101.6-millimeter (4-inch) bevel (regardless of barrel size) along the top of
the wingwalls and the top edge of the culvert entrance. The most efficient
configuration tested was the model of the cast-in-place box culvert.

Stress Cracking Potential for HDPE Geogrids
FHWA-RD-97-142
This report describes the development of a testing protocol
designed to measure the potential for stress cracking of high-density polyethylene (HDPE) geogrids used for soil
reinforcement. The collected data demonstrate that local stress cracking in the
unoriented transverse node of HDPE geogrids can occur as a result of
construction-induced damage. Undamaged geogrids are not prone to stress
cracking at load levels below their 100-year limiting creep load.
