Fixing
bridges and roadways: While not suited
for use as a large-scale substitute for cement because of higher initial cost,
Argonne's phosphate-bonded ceramic material Ceramicrete is ideal for
applications like bridge and road repair. The material mixes at room temperature,
does not require firing to set, is harder and denser than Portland cement,
and binds to nearly any solid object, including cement and itself. Ceramicrete's
curing process is exothermic, which means it generates heat. Argonne has tested
uncured Ceramicrete in ice water and found that it cured in less than two hours.
It is lighter than cement and more impervious to water. Samples of the material
are available for testing. Contact Terry Maynard (630-252-9771,

Making travel safer and more efficient: Working with government agencies, universities, and private industry, Argonne researchers bring skills in transportation research, electronics, telecommunications, and high-performance computing to Intelligent Transportation Systems (ITS) programs. By linking drivers, global positioning system satellites, traffic control centers, traffic signals, and"smart vehicles", ITS delivers up-to-the-minute traffic and routing information. ITS could have an impact comparable to the development of the national highway system, making travel safer and more efficient. Less traffic congestion also will mean less fuel burned, lower emissions, and fewer accidents. Argonne's work on this innovative use of technology includes (1) the ADVANCE Project, which tested a dynamic guidance system of"mobile navigators" in Chicago, (2) the GCM (Gary, Chicago, Milwaukee) Corridor program to test ITS, (3) the ITS Simulator Project, which models ITS under real-world conditions, and (4) working with NASA's Jet Propulsion Laboratory and the Chicago Fire Department, a study of ways to track cross-country hazardous materials shipments and respond more quickly when accidents occur.
Laser glazing reduces friction, preserves rails:
Research at Argonne shows that treating steel rails with a process called laser
glazing reduces friction between the rails and train wheels by 40 percent.
Railroad companies estimate that reducing rail-wheel friction can save $40
million per year in fuel costs; save another $16 million per year in the cost
of rail replacement; and reduce the likelihood of derailments, thereby saving
lives. Friction is necessary on the rail tops for traction, but rubbing between
the wheels and the sides of the rail causes many problems. The drag forces
produced by rubbing increase fuel consumption, wear away the rail, initiate
cracking (which can lead to rail fracture and derailment), and can even force
the wheel to climb over the rail (another cause of derailments). Such liquid
lubricants as oil and grease, currently used to reduce friction, wash away
in the rain, introduce environmental problems, and may cause a train to lose
traction if they migrate to the top of the rail. The solid-state lubricant
that results from laser glazing is durable and environmentally benign, stays
where it is applied, and can be applied to rails both during fabrication and
in service. For more information, contact Cindy Wesolowski (800-627-2596, partners@anl.gov).
Addressing"what if"concerns--hazmat transportation
risk assessment/analysis, modeling, and planning: Argonne has developed
a comprehensive assessment approach to estimate the risks associated with
transporting hazardous chemicals and radioactive materials. The approach
addresses risks unique to radioactive and hazardous waste shipments and those
that result from the transportation operations themselves. The U.S. Department
of Energy (DOE) developed a comprehensive approach for estimating the risks
from waste shipments of all types within the DOE complex. The approach relies
upon the application of a set of risk assessment models, including two developed
by Argonne specifically to make the set comprehensive and responsive to public
concerns and DOE commitments, as illustrated in many major DOE environmental
impact studies. Argonne's RISKIND computer code analyzes radiological consequences
and health risks to individuals and collective populations from exposures
associated with transporting spent nuclear fuel and other radioactive materials.
The code was designed to address areas of specific concern to individuals
or population subgroups and includes numerous user-friendly features to facilitate
its use by decision makers and others. A similar code, RISKCHEM, is being
developed to estimate accident consequences and health effects from transportation
accidents involving hazardous chemicals. Argonne is also a lead laboratory
in a recent DOE Transportation Risk Assessment Working Group whose mission
is to harmonize DOE complex-wide transportation risk assessment. Contact S.Y. Chen (630-252-7695).
