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...
Field Performance of Fiber Reinforced Concrete Highway Pavements
This paper reports the evaluation of field performance of fiber reinforced concrete pavements. The concrete was designed for a compressive strength of about 40 MPa. Steel fibers with hooked...
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...
Curing Time for CRCP Mixtures Based on Flexural Strength
In this paper, the effect of different curing conditions on the flexural strength is investigated, and also the minimum required period for moist curing is found. The combined effect of...
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...
Brittleness of High Strength Concrete
Fracture mechanics approaches are needed to determine material parameters which are related to the brittleness of concrete and its structural response. The size effect method is used to...
Concepts for Hybrid FRP Bridge Deck Systems
This paper presents selected structural concepts for modular bridge deck systems taking into account the limitations imposed by fabrication processes for polymer matrix composites. An...
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...
Durability of High-Strength Concrete Containing Fly-Ash and Silica Fume
The durability of high-strength concrete made with local materials were tested with regard to the freezing and thawing resistance of concrete in accordance with ASTM C666 procedure A....
High Early Strength Concrete Containing Large Quantities of Fly Ash
This paper presents results of research performed at a precast/prestressed concrete plant to identify optimum mix proportions for production of high early strength concrete with high fly...
Properties of Flyash Cellular Concrete
A research program was conducted with the aim of studying the physical and flexural properties of cellular concrete containing flyash. Two different types of fibers were also added to...
Thermomechanical Damage Due to Hydration in Large Concrete Dams
This paper presents the bases of a thermomechanical model able to describe the main evolution of concrete properties with aging. The model is based on the 'maturity'...
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...
Environmental Considerations in the Design of Asphalt Concrete Paving Mixtures
The design of asphalt concrete mixtures is largely based on two empirical mixture design methods. These are 'Marshall' and 'Hveem',...
