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.

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.

Supplemental Reference Appendices for An Introduction to the Deep Mixing Methods as Used in Geotechnical Applications, Volume II: Appendices

FHWA-RD-99-144

This report traces the historical development of the various proprietary deep soil mixing methods and provides a structural summary of applications. It also compares the applicability of the deep mixing method with other competitive forms of ground treatment and improvement. The deep mixing method is an in situ soil treatment technology in which the soil is blended with cementitious and/or other materials.

Techniques for Measuring Existing Long-Term Stresses in Prestressed Concrete Bridges, Volume 1: Analytical, Laboratory, and Field Studies

FHWA-RD-99-178

This report summarizes the analytical, laboratory, and field studies performed to evaluate the feasibility of the flat-jack direct stress measurement technique to be used on prestressed concrete bridges. Several strain relief methods, including boring and slitting techniques, were evaluated by performing analytical studies. The flat-jack slitting technique was determined to be the most promising.
