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...
High Strength, High Denier Discrete Polymer Fiber in Cementitious Composites
A series of 3-point beam tests were performed on the cementitious composites specimens reinforced with high strength, high denier discrete polyester fibers. The fiber length, fiber volume...
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...
Brittleness Index of Cementitious Composites
Series of direct tension tests were conducted to observe the softening response of different types of cementitious composites, namely, mortar, plain concrete, high strength concrete, normal...
Composite Applications in Highway Bridges
This report presents a summary of a four year research effort titled, 'Transfer of Composite Technology to Design and Construction of Bridges'. Extensive analytical...
Laboratory Fatigue Investigation of a GRP Bridge
A fatigue study of a 4.9 m glass-reinforced plastic bridge indicated a resistance to 1.6 million cycles of load without extensive damage to joints or elements. Viscoelastic creep occurred...
Development of High Strength Composite Cables
Fiber reinforced composite materials offer significant advantages over conventional materials for such factors as corrosion resistance, lighter weight, and higher strengths. These advantages...
Drying and Shrinkage of Concrete: The Case of Massive Parts
The natural drying of concrete induces a number of intense mechanical effects on the structures. These various effects are of importance to engineers: in the design stage (estimate of...
Effect of Environment on Durability of Pavement Materials: An Overview
The best known causes of material degradation in pavements include environment, traffic loads, and the use of substandard materials. Presented in the paper is a critical review of the...
Fatigue Behavior of Bond-Anchored Unidirectional Glass-FRP's
The contribution reports on the fatigue behavior of fiberglass reinforced plastic (FRP) bars, consisting of endless E-glass fibers embedded in a polyester (PE) matrix and anchored in a...
Uni- and Bi-Axial Compressive Fatigue of Fiber Concrete
Fatigue behavior of fiber reinforced concrete is studied under uniaxial and biaxial loadings. The S-N curves and the cyclic deformations of fiber concrete are compared to those of plain...
Flexural Behavior of Synthetic Fiber Reinforced Rapid Set Materials
This paper presents the results of a laboratory investigation on the contribution of synthetic fibers to the flexural behavior for three typical rapid set materials. Three types of synthetic...
Application of Waterjet Cutting for Pothole Repair
A study was conducted to determine the feasibility of utilizing high pressure waterjet cutting technology as an infrastructure maintenance tool. The influence of waterjet cutting parameters,...
Behavior and Strength of Telescopic Steel Shores
To study the load distribution between concrete floors and shores during construction, the non-linear axial load-shortening behavior of a single post shore must be modeled properly. In...
Compressive Strengths of Lean Concretes Containing Fly Ash
The compressive strength development of lean concretes containing fly ash was evaluated. Concretes were prepared at total cementitious materials contents of 423, 517, and 564 lb/yd3...
Anomalous Structural Size Effect in Cohesive Materials Like Concrete
This contribution analyses on theoretical grounds the size effect trends in special cases where - unlike most experimental situations in fracture research - the specimen is not precracked...
Design and Performance of Earth Retaining Structures
The proceedings of the 1990 Specialty Conference on Design and Performance of Earth Retaining Structures was held in Ithaca, New York from June 18-21, 1990. It presents a total of 50 papers...
