A Laboratory Investigation on Long-Term Performance of Asphalt Concrete Treated with Antistripping Additives
Asphalt concrete pavement is susceptible to moisture damage and the damage caused by repeated freeze-thaw cycles is a major problem. This paper summarizes a laboratory investigation for...
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...
Concreting at Subfreezing Temperatures
Temperature affects the rate at which portland cement concrete develops strength. Below about 20?C, strength gain is retarded, whereas at higher temperatures it is accelerated. Strength...
Implementation of Material Requirements in Specifications
This paper focuses on where to find information on materials, their compatibility, minimum standards and specifying of materials and their use. The paper also presents case histories on...
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...
Bond Strength of Straight GFRP Rebars
An overview of a study on bond of straight Glass-fiber-reinforced-plastic (GFRP) rebars to concrete is presented. The 54 specimens to be tested include several variables, such as the mode...
Feasibility of FRP Molded Grating-Concrete Composites for One-Way Slab Systems
This paper describes the behavior of one-way concrete slabs reinforced with Fiberglass Reinforced Plastic (FRP) molded grating. FRP molded grating is commercially available and is mainly...
Behavior of Externally Confined Concrete Columns
This paper investigates the feasibility of strengthening of seismically deficient concrete columns with high-strength fiber composite straps. The concrete columns will be externally confined...
Fiber/Epoxy Composites Strengthen Bridge Columns
The California Department of Transportation is using high strength fiber/epoxy composites to strengthen existing reinforced concrete bridge columns. These advanced composite materials...

Dynamic Parameters Analysis of Piles
This paper presents an analysis for the dynamic parameters of a single pile. The analysis allows consideration of pile-soil interaction, soil natural layered behavior and floating pile...
Cyclic Behavior of a Deepwater Normally Consolidated Clay
A comprehensive advanced laboratory testing program was undertaken to study the cyclic behavior of clays under various combinations of one-way and two-way cyclic loading. This work was...
A New Concrete Armor Unit for Breakwaters: The Beta Block
The aim of this paper, is to present a new artificial block for the protection of breakwaters. This armor unit, named BETA, has been designed and tested in the Coasts and Harbors Studies...
Dynamic Response Characteristics of Jack-Up Drilling Units
The effects of five parameters on the dynamic amplification of the global base shear on a deep water jack-up drilling unit were analyzed using a time domain nonlinear model. The five parameters...
Response Statistics of Tension Leg Platforms Under Wind Loads
This paper presents the direct integration method and Kac-Siegert technique to solve the first four cumulants in the general quadratic systems, and proposes the splitting technique to...
Fiber Ropes for Ocean Engineering in the 21st Century
Recent advances in synthetic fiber ropes will greatly influence the practice of civil engineering in the oceans during the 21st Century. New fibers have moduli almost as high as steel...
Laboratory Methods for Preparing Low-Density Frozen Saline Soil Samples
Laboratory methods were developed for preparing low-density frozen saline soil samples with density values ranging from 85-110 lb/ft3. This range...
A Laboratory Study of Shock Waves in Frozen Soil
This work has focused on two aspects of dynamic behavior of frozen soil: first, on the shock pressure attenuation, and second, on the shock Hugoniot. The use of long bars of frozen soil...
The Effect of Loading Rate on the Bending Strength of Alluvium Reinforced Ice
Traditional building materials are often less than ideal for construction in remote Arctic locations. Their mechanical properties may be degraded in extreme cold, and costs associated...
