Use of Geogrids on Soft Deposits
The construction of highway embankments over soft and waste deposits required the use of geogrids as an economical alternate to conventional methods of 'remove and replace'....
Sawn Lumber in Bridge Construction
This paper covers many aspects of design and construction that affect the specifications of the sawn wood components of a highway bridge. The relationships between the grading rules for...
Glued Laminated Timber for Bridge Construction
Structural glued laminated timber (glulam) was first introduced into the U.S. as a construction material in 1934. With the development of fully waterproof adhesives in the 1940's,...
Structural Wood Composites in Bridge Construction
Wood composites, known collectively as Structural Composite Lumber (SCL), are a family of wood-based products that better utilize the available wood fiber of a tree. This paper describes...
Applications of Wood Materials for Innovative Bridge Systems
This paper describes completed research and the status of research underway on timber bridges that are part of the USDA Forest Service timber bridge initiative. The initiative includes...
Improved Prediction of Masonry Durability Through Advanced Materials Science Methods
Several trends in the use of materials in civil engineering have made it imperative to improve the ability to predict the durability of masonry. This will require more emphasis on materials...
Premature Failures of Outdoor Masonry Pavements
The authors have investigated and repaired a number of premature inservice failures of masonry paving systems in recent years. These systems have become common, built over underground...
Performance of Latex-Modified Thin-Set Mortars in Applications of Thin-Brick Veneer
The use of field-applied polymer-modified mortars for adhering thin brick or tile to building exteriors has become increasingly common in the last decade. The latex-modified mortars can...
Use of Voluntary Consensus Standards by the Bureau of Reclamation
This paper outlines how the Bureau of Reclamation has historically participated in standards development for emerging technologies, and how present standards are applied or adapted for...
Are ASTM Standards Enough?
ASTM (American Society for Testing and Materials) is most likely the World's most renown developer of voluntary consensus standards. Its standards development process utilizes...
Construction Quality Assurance for Geomembranes
The results of and lessons learned from construction quality assurance (CQA) programs on 19 geomembrane liners are presented. The specifications are generally exceeded by comfortable margins...
Spectral Techniques for Serviceability and Durability Assessment of High-Performance Construction Materials
Using spectral techniques, one can obtain the frequency content of a material specimen. Spectral measurements were made on specimens of Portland cement and a polymer based materials. In...
Design of Fiberglass Reinforced Plastic Underground Storage Tanks
The purpose of this paper is to discuss the design and construction techniques of fiberglass composite underground storage tanks. The scope of this paper is limited to the straight shell...
Three Tools for Design Test Bed Analysis
Three analytical tools are outlined for use in design test bed work focusing on the design/production interface. The tools are substitution analysis, coupling analysis, and value chain...
Material Properties Related to Pavement Performance
As part of the Strategic Highway Research Program, an effort has been made to review research literature which can be used to relate asphalt properties to pavement performance. This report...
Relationship Between Laboratory Aging Tests and Field Performance of Asphalt-Concrete Mixtures
Aging of asphalt mixtures is primarily associated with loss of volatile components and oxidation in asphalt during the construction phase (short-term aging), and progressive oxidation...
70 Year Performance Record for High Strength Structural Lightweight Concrete
The paper briefly discusses the first ship built using expanded aggregates manufactured in a rotary kiln the USS Selma. It then goes on to discuss achieving high strength concrete with...
Montana's Approach to Reduce Asphalt Pavement Rutting
The Montana Department of Highways experienced premature rutting in some asphalt concrete pavements primarily on the east-west interstate in Eastern Montana. Montana participated with...
Experimental Mixes to Minimize Rutting
This report describes the materials and construction details involved in the design and placement of four experimental mixes on I-95 (Richmond-Petersburg Turnpike) in 1985 and follows...
Concrete Pavement?Specification by Modeling
Concrete pavement specifications have traditionally been prescriptive with construction in-put defined. This practice does not include a definition of the product intended, restricts innovation,...
