Asphalt Age Hardening?Trends and Predictions
Pavement cracking is substantially related to the consistency of asphalt cement binders. The variation in hardness of binders is related primarily to asphalt characteristics, environment...

Recognition and Avoidance of Details That Adversely Affect the Performance of Exposed Wood Members
Factors that affect the deterioration of wood in structures are reviewed. Important points regarding wood-moisture relationships are noted. The requirements for decay of wood by fungi...

Protection of Wood Designs in Adverse Environments
Engineers and architects are becoming increasingly aware of the risks of poor wood design practices and the benefits of using wood properly. This paper addresses biological factors that...

Long-Term Performance Reliability of Wood Materials
The United States faces a major task in maintaining and rebuilding the nation's infrastructure in the 1990's and beyond. Economic constraints have limited funds...

Methods for Assessing Wood Structures in Place
The Forest Products Laboratory is developing a comprehensive guideline for assessing the condition of existing wood structures. This paper provides an overview of the current literature...

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...

Building Joint Movement
Moisture leakage in masonry claddings occurs not only through copings and facial separation cracks, but also through failed sealant joints in the veneer. The factors affecting joint movement...

Asphalt Cement Specifications and HMA Performance
The standard specifications generally used for hot mix asphalt (HMA) are those published by the American Society for Testing and Materials (ASTM) or the American Association of State Highway...

Fiber Reinforced Plastic Grids for the Structural Reinforcement of Concrete
The use of fibre resin plastic grid is investigated as a primary bending reinforcement in concrete members. Laboratory bending data is compared with theoretical results using ACI 318-83...

Practical Prediction of Concrete Shrinkage and its Uncertainty
An improved prediction model for shrinkage is proposed. The main features are (1) diffusion-type size dependence for humidity effects, (2) initial and final asymptotic forms of the shrinkage...

A Test Method to Evaluate Shrinkage Cracking of Concrete
The possibility of shrinkage for a given drying environment depends on the following factors: free shrinkage, creep, and age-dependent properties of concrete. A common way to account for...

A Prestressed Kevlar/FRP Structural System
The strength/stiffness characteristics of a new lightweight composite structural system have been investigated in this study. The proposed system is constructed of FRP(E-glass/isophthalic...

U.S. Coast Guard Experience with Commercial FRP Vessels with Respect to Structural Reliability
The U.S. Coast Guard currently inspects over 1000 fiber reinforced plastic (FRP) vessels used in commercial passenger service. The designs include monohulls, catamarans, hydrofoils and...

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...

Effect of Fly Ash on the Microstructure and Durability of Concrete
The influence of fly ash on the microstructure and durability of concrete was investigated. It was found that the use of 50% fly ash in concrete reduced greatly its resistance to freezing-and-thawing...

Permeability Effects on the Sulfate Resistance of Concrete
A laboratory study was conducted to determine the effect of permeability on the sulfate resistance of concrete containing fly ash. Concrete specimens were moist cured for 7 and 100 days...

A Comparison of Straight and Circular Fibers for Concrete
Two previous studies of concrete reinforced with closed loop fibers are reviewed. Statistical moments of fiber systems are derived, including the expected values of the fiber embedment...

An Extended Mixture Approach for Modeling of Fiber Reinforced Cementitious Materials
A rate-independent, anisotropic model for Fiber Reinforced Cementitious Materials (FRCMs) is presented. A continuum damage/plasticity model for the concrete and an effective fiber model...

Innovative Uses of Polymer Concrete
Polymer concrete (PC) was developed in the 1950s. The material became more widely known in the 1970s when it was used for the repair of portland cement concrete. Polymer concrete is significantly...
