History of Hot Mix Asphalt Mixture Design in the United States
Asphalt has been used as a construction material from the earliest days of civilization, but though it has long been used as a waterproofing material in shipbuilding and hydraulics, its...
For the Duration
The U.S. Army Corps of Engineers developed a new grouting method called duration grouting when constructing the foundations for the Portugues Dam in Ponce, Puerto Rico. The site is marked...
Utilization of Lagoon-Stored Lime in Embankment Construction
The maximum percentage of lime that can be mixed with a predetermined borrow material to build the proposed road embankment without adversely affecting the physical and mechanical properties...
Great Grouts (Available only in Geoenvironmental Special Issue)
Particulate grouting has long posed challenges to those in the geotechnical field. But significant developments in the understanding of hydration and rheology control look promising. Modern...
Adhesion Kinetics of Fuel Oil #6 and Oil-in-Water Emulsions on Marine Sediments under Turbulent Mixing Conditions
Oil spilled in the marine environment is subject to a great variety of physical, chemical and biological processes, which determine its ultimate fate in the aquatic environment. Many of...
Treatment of Oil in Water Emulsions by Ceramic-Supported Polymeric Membranes
A novel membrane was developed by growing polymer chains from the surface of a porous ceramic support, resulting in a composite membrane which combines the mechanical properties of the...
Thermally Enhanced Bioremediation of a Gasoline-Contaminated Aquifer Using Toluene Oxidizing Bacteria
The combined application of steam injection and vacuum extraction has proved to be very effective for the in situ remediation of a gasoline contaminated aquifer. It is expected that the...
Vertical Sorting Within Dune Structure
Sediment transport occurs in natural stream beds at least in part as bed load. These bed forms are typically classified as ripples or dunes depending on the bed morphology and flow conditions....
Measuring Air Concentration in Flowing Air-Water Mixtures
This paper describes the use of an electrical conductivity probe to determine aeration of a plunge pool by an overfall nappe. The probe was calibrated using an apparatus designed to provide...
Application of a Needle Probe in Measuring Local Parameters in Air-Water Flow
In this paper, development of a double needle probe for measuring local parameters in air-water mixtures is explained. This probe is designed to measure flow velocities up to 10 m/s and...

Advances in Dry Shotcrete Technology by Means of Microsilica
During the last decade microsilica has been increasingly used to improve both wet and dry mix shotcrete. In the traditional dry process microsilica is blended in the dry mixture. Since...
Experimental Synthesis of Crystalline Matrices Based on Ce, Ba, Sr Zirconates for Immobilization of High-Level Radioactive Actinides
Experimental investigations are carried out at the Radium Institute to create different by their properties crystalline matrices, alternative to SYNROC, for incorporation of partitioned...
Modeling Adsorption of Mixtures of Radionuclides by Zeolitized Tuff
Multi-solute sorption isotherms were measured using 'nonscents', a zeolitized volcanic tuff material from Southeast Arizona. Isotherms for the three constituent binaries, Sr-Co, Cs-Sr...
Steps to a Mix Design Solution for Better Asphalt
Three primary products will be delivered at completion of the Asphalt Research Program of the Strategic Highway Research Program, a performance based asphalt binder specification, a performance...
Gyratory Testing Machine Usage in Monitoring HMA Quality
This paper describes research conducted by the Mississippi Department of Transportation to investigate the potential of the U.S. Army Corps of Engineers' Gyratory Testing Machine (GTM)...
How SHRP Reliably Predicts Pavement Performance
One of the important results of the SHRP Asphalt Research Program was to develop a comprehensive pavement performance model that reliably predicts rutting, fatigue cracking and thermal...
Using SHRP Tests to Evaluate CRM Asphalt Pavements
During the recently completed Strategic Highway Research Program (SHRP), there was insufficient time or funds to evaluate the inclusion of waste materials in asphalt paving mixtures. However,...
An Evaluation of the Strategic Highway Research Project Packing Handbook
The objective of this paper is to present the use of the November 8, 1991 SHRP C-206 report entitled `Packing Handbook - A Guide to the Optimal Gradation of Concrete Aggregates'. The purpose...
Application Cases of Slurry Seal in Japan
In Japan, slurry seal began to be used for repairing asphalt pavements at around 1963, mostly for repairs of prefectural and municipal roads. In recent years, however, it has rarely been...
