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...

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...

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....

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'...

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',...

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,...

Localization Instabilities Due to Damage and Fracture Propagation: Application to Tensile Specimens
In recent research it has become clear that localization of damage due to strain softening as well as propagation of interactive cracks can result in bifurcations of the loading path characterized...

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...

Site Assessments
The 1986 Superfund Amendment and Reauthorization Act (SARA) established an innocent purchaser defense applicable if a new owner conducts appropriate inspection and appropriate inquiry...
