Concrete Bridge Protection Repair & Rehabilitation
A methodology for the selection of cost effective solution(s) to the protection, repair, and rehabilitation of concrete bridges in chloride-laden environments is presented. The methodology...
Snow and Ice Control in Japan and United States
Both Japan and the United States experience severe winter conditions that require major resources and large expenditures for maintaining highways. The maritime climate that prevails in...
Bonded Concrete Overlays for Rehabilitation of Continuously Reinforced Concrete Pavement
As a result of the 1991 Intermodal Surface Transportation Efficiency Act (ISTEA), significant funding is now available for the rehabilitation of the nation's Interstate highway system....
A Revised Methodology to Minimize Bias in Determining the Porosity and Void Tensor of Particulate Media
Increased recognition of the importance of fabric in the observed response of particulate media under monotonic and cyclic loading has led to the development of new procedures to quantify...
Densification of Asphalt Pavements by Traffic
Since asphalt pavements rut when the voids are filled with asphalt (and voids can become filled by traffic densification) the voids that develop under traffic are vital to any mix design...
Rehabilitation of Runway 4R-22L at Chicago's O'Hare International Airport
This paper describes the systematic process that was used to develop a rehabilitation strategy for the busiest runway at O'Hare International Airport. Any rehabilitation alternative that...
A Marketing Analysis of an Old Concept: the Horizontal Elevator-Monorail
The objective of this research is to define an efficient and cost effective concept for an Automated People Mover (APM) System. Current solutions are relatively expensive to install, have...
Technological Innovations: Opportunities to Reduce Costs
This paper presents a comparative study of an automatic dedicated single track people mover and an automatic dedicated double track people mover. The study examined both `system' and infrastructure...
Cable-Drawn Systems in Shuttle Applications
Cable-drawn Automated People Mover systems have long been regarded as having technology restrictions which often preclude them from being considered for many applications. However, for...
The MK II Art System?A New Generation of Automated Guideway Transit
Bombardier is well advanced in a program to produce a larger version of its successful Advanced Light Rapid Transit (ALRT) vehicle which is in service in Detroit, Scarborough (Toronto)...
The Optimum Gravity Dam
A method is presented for optimizing the cost of a dam by varying the properties of the material and the shape of the dam to produce the lowest cost water barrier to perform the required...
Chesapeake Bay Field Modeling and Monitoring Projects
'Traditional' erosion control measures often do not meet the corps of Engineers' requirement for economic justification. The costs of these measures are much greater than the benefits...
Evaluation of Concrete Bridges by Impact-Echo
Strength of post-tensioned bridge structural members primarily depends on the tensile capacity of their post-tensioning steel reinforcement. To prevent corrosion, the post-tensioning steel...
Frequency Spectrum Analysis of Ultrasonic Testing Signal in Concrete
Description is given on high-speed sample apparatus connected with the CTS-25 low frequency ultrasonoscope and computer, the time domain of ultrasonic testing signal is transformed to...
Reassessing the Risk Assessment
Risk assessments should help an engineer determine cost-effective remedies to environmental pollution. Unfortunately, most don't. Most assessments drastically overestimate...
Landfills: Anatomy of Automated Design
California's 360 acre Bee Canyon landfill (completed last year) sits amid a complicated network of narrow canyons with side slopes 300 ft high. As with most landfill projects,...
Value Engineering at a Superfund Site
The Helen Kramer Landfill ranked fourth on the EPA's National Priorities List and the estimated cost of clean up was about $39 million. By value engineering selected parts...
Design Cable-stayed Bridge for Cost Effectiveness and Safety
Innovative design approach is needed to enhance the prestigious status enjoyed by cable-stayed bridges. The present paper aims at such a goal of cost effectiveness and safety by providing...
Mechanical Characterization of the Soft Tissue in Horse Hooves
The laminar corium tissue of the equine distal digit (or horse hoof) has been tested uniaxial tension. The laminar corium tissue lies between the hoof wall and the underlying bone of the...
Mathematical Characterization of Fabric and Its Use in Mechanics of Geomaterials
Increased evidence of the influence of their discrete nature on the observed behavior of geomaterials has prompted a number of investigators to look at these materials at the microstructural...
