Evaluation of Fine Aggregate Particle Shape and Texture
In an effort to minimize or eliminate permanent deformation (rutting) of heavy duty asphalt pavements most governing agencies now limit the amount of natural sand which generally (not...

Realistic Specifications for Manufactured Sand
Data which demonstrate the beneficial effect of using fine aggregate having high fines contents on concrete properties are presented. All data indicate that the use of a high fines content...

High Strength, Low Permeability Garage Rehab Concrete
Physical and engineering properties of high strength structural lightweight concrete used to replace deteriorated concrete in garage structure rehabilitation programs are reported. Structurally...

Forensic Analysis Techniques for Joint Sealants
Growing concerns involving the field performance of pavement joint sealant materials has illustrated the need for forensic capabilities in determining the cause of sealant failures. Methods...

Performance of Free Draining Base Course at Fort Campbell, Kentucky
In 1990 a free draining base course layer was constructed in the structural section of a pavement to be used as a military vehicle maintenance yard at Port Campbell, Kentucky. The Corps...

A Theoretical Approach to Characterize Reinforced Concrete Using Stress Waves
Although advances in nondestructive evaluation of structural concrete have been made, the ultrasonic determination of the placement of steel reinforcement in concrete remains difficult....

Investigation of Concrete at a Middle East Plant
In recent years, reinforced concrete construction in the Middle East has been beset by durability problems. The causes include availability of a limited number of skilled workers, marginal...

Innovations for NDT of Concrete Structures
The proposed paper presents three recent innovations for sonic and ultrasonic Non-Destructive Testing (NDT) of concrete structures which greatly increase the utility and speed of many...

Unidirected Twined-Strand Composites and Their Uses
Twined strand composites are a new class of unidirected continuous-fiber-reinforced composite materials where the orientation of the continuous fibers is a twine of unidirected helically...

Adhesives and Structural Plastics
An overview of some primary considerations for the use of adhesives and their advantages in connection of structural plastics is presented. Effective joint geometries, surface preparations,...

Full Scale Tests on Concentrically Loaded Fiber-Reinforced Pultruded Columns
This paper briefly reports on the experimental investigation in connection with the short term behavior of pultruded structural members under concentric loading. In particular, results...

Glass-Fiber Reinforcing Rod: Characterization and Application to Concrete Structures and Grouted Anchors
This paper presents the physical and mechanical characteristics of a new glass-fiber reinforcing rod which was developed to be used as a rebar for concrete structures or a tendon for grouted...

Splice/Development Length Requirements for FRP Grids Used in the Structural Reinforcement of Concrete
The research presented in this paper program was directed towards determining development length and splice requirements for FRP grids used in the reinforcement of concrete structures....

Hybrid (FRP+Steel) Reinforcement for Concrete Structures
The most popular method to prevent corrosion of steel rebars and prestressing tendons is epoxy coating. This paper presents an alternative approach consisting in the combination of a fiber-reinforced-plastic...

Investigation of the Behavior of Reinforced Plastic Columns with Concrete Core
This paper describes an experimental investigation into the behavior of reinforced plastic columns with tubular (hollow) sections. The columns were pultruded and had a cross-section which...

Behavior of Concrete-Graphite/Epoxy Sections in Composite Bridge Girders
The focus of this work is on the behavior of composite bridge girders constructed from carbon-fiber-reinforced-plastic sections and concrete slabs. The study examines four-point bending...

Structural Performance of Hardwood-Metal Composite Beams
This research examines the deflection characteristics of layered timber/steel composite beams with hopes of applying such principles to large timber structures such as highway bridges....

Sprayed-Zinc Galvanic Anodes for the Cathodic Protection of Reinforcing Steel in Concrete
Corrosion of reinforcing steel bars (rebars), due to penetration of chloride ions from seawater affects the substructure of many bridges in marine service. In a new, low cost control method,...

Probabilistic Mechanics and Structural and Geotechnical Reliability
This proceedings consists of summary papers for the thirty-six technical sessions of the 6th ASCE Specialty Conference on Probabilistic Mechanics, and Structural and Geotechnical Reliability....
