Concrete Construction on the Moon
Building bases on the Moon, according to Space Exploration Initiative, may start in the early 21st century. Concrete, as versatile as it has been, might become the prime material for construction....
Fine Tuning the Airfield: The New Denver International Airport
This paper discusses airfield layout considerations that have been incorporated into the design of the new Denver International Airport (DIA). These concepts include some unique provisions...
Characteristics of High-Speed Runway Exits for Airport Design
This paper addresses some of the geometric design and operational characteristics of high-speed runway exists. Lateral and longitudinal runway constraints limiting the use of high-speed...
Design Considerations for Multi-Wheel Aircraft
The available test data for performance of flexible pavements were analyzed using the Boussinesq and elastic layered theories. It was shown that strain criteria could be developed for...
Studies Related to Aircraft/Runway Friction Performance
Gaining a better understanding of the many factors influencing the tire/runway friction interface is the aim of several ongoing NASA Langley research programs. Results from studies conducted...
The Army Aviation Team from a Military Civil Engineer's Perspective
The Technical Session for which this paper is written is 'Airfield Pavements - A Team Effort.' As such, the emphasis on this paper is the United States Army Aviation Team, and not the...
The New Munich Airport?Planning, Construction and Opening of a New International Turnstile Airport in Europe
The new Munich airport that began operations just recently dates back to the mid-1950. The paper discusses the general expansion plan which includes site selection; runway system planning;...
New Seoul Metropolitan Airport
The New Seoul Metropolitan Airport (NSMA), to be built on a man-made island near Seoul, Korea, will have access to the city by bridge, rail, and dedicated freeway. When completed, NSMA...
Management of Design
Denver's new airport uses the services of over 80 separate design firms. The existing airport, Stapleton, could not be expanded to meet the forecasted demand of 1,200,000 operations with...
Nondestructive Testing of Concrete Elements and Structures
Quality of a concrete structure depends on good construction practice. On the other hand, continuous repair and maintenance preserve the quality of construction. Nondestructive evaluation...
Fiber: Good For the Concrete Diet?
Fiber reinforcement of concrete has many advantages, but after thirty years of research those benefits have most often been seen in a laboratory. Some materials, such as synthetic fibers,...
Adding Up Admixtures
The importance of preventive maintenance and lifecycle costs has put added emphasis on concrete performance. For many specifiers, chemical admixtures, added to concrete at the batch plant,...
A European Road Comes to the U.S.
From Sept. 7 to Sept. 22, a group of 21 federal and state transportation officials and industry representatives participated in the European Asphalt Study Tour, traveling the roads of...
Sydney Airport International Terminal Development
The existing International Terminal at Sydney (Kingsford Smith) Airport-KSA-is overcrowded and providing a low level of service. Planning for an expanded facility catering for KSA needs...
A Current Review of Experience with Asphaltic Concrete Impervious Membranes on the Upstream Slope of Earth and Rockfill Dams
At some sites where an earth or earth-rock dam is being considered, studies may indicate that the most economical and satisfactory dam would be obtained with a pervious embankment of soil...
Controlled Braking on Uneven Roads
The braking process of a passenger car may be influenced by a large number of variables relating to driver, vehicle, brake system, tire-road interaction and ambient conditions. Because...
Experimental Study of the Transient Temperature Distributions in Concrete
A small scale, preliminary experimental effort to quantify the randomness of the thermal diffusivity of concrete has been undertaken. Two sets of cylinders have been instrumented with...
A New Probabilistic Model for the Fracture Toughness of Concrete
Scatter of strength and toughness parameters as well as scale effect are often observed in brittle materials such as concrete. The recently developed Crack Diffusion Model is utilized....
Stochastic Modeling of Short Fiber Reinforced Composites?A Review
Since the early 1960's, an extensive research and development has been carried out with fiber reinforced cements and concretes. Modeling of such heterogeneous material is still in the...
