Concrete Production Method for Construction of Lunar Bases
If a permanent lunar base is to be built on the Moon, most of the materials for the construction would be made from in situ resources. From economic viewpoints, concrete would be the most...
Concrete Habitable Structure on the Moon
This paper presents construction methods for a concrete habitable structure on the Moon. The study was conducted on the assumption that a concrete manufacturing plant has already been...
Planetary Base Inflatable Form Construction
The use of the inflatable form (IF) structure has been practiced in the concrete industry for more than a decade. This article proposes the use of a double-walled IF for the Phase I construction...
Structural Art in the Lunar Environment
Building structures will be a necessary part of extending our presence on the moon. In designing and building these structures, aesthetic value will play a prominent role. History shows...
The Eccentric Entrance
Architects design irregularly shaped buildings to give their clients something different, and this creates problems for structural engineers, especially in earthquake zones. The Brinderson...
Driving in the Fast Track
Fast track concrete allows traffic back on pavement within 24 hours. Fast track concrete has been developing in Iowa for the last three years. Traffic rerouting, an inconvenience that...
Leakproofing an RCC dam
A roller compacted concrete dam, Stacy Dam in Texas, is described and several methods of preventing leakage are mentioned. Reinforced concrete facings, placed after RCC completion, was...
Stopping the Cracks
It is generally agreed that reinforced concrete in parking garages especially in the deicing salt environment is exposed to unusually hostile service conditions. Deterioration of reinforced...
Structure as Architecture
The newest structure at Tampa International Airport in Florida is Airside F, part of an expansion of the first airport designed so that passengers are shuttled via monorail between a main...
The Precast Pier
For the U.S. Navy's Strategic program, a 1,410 ft long pier was constructed on New York City's Staten Island. The combined efforts of three engineering firms,...
Making Use of Contaminated Soils
Using hot-mix asphalt (HMA) is one answer to contaminated soil. HMA plants can be modified to accept some contaminated soil�a boon not only to the generator of the soil but the asphalt...
Pipe Jacking Advances
Pipe jacking is the remote placement of pipes underground by means of a tunneling machine that carries a train of pipe behind it. This is a relatively new technology in the United States,...
New Horizons in Construction Materials
While civil engineers have, for centuries, built structures and other physical facilities using whatever materials are available to them, there is always the need for stronger, more durable,...
AASHTO Design Concepts
The AASHO Road Test of 1958-60 grew out of a need to quantify the effects of increasingly heavier axle and gross loads and varying wheel load configurations on the performance of this...
Concrete Pavement Rehabilitation Research Findings
A study to improve the procedures for evaluating and rehabilitating concrete pavements was undertaken in 1985. Field and analytical studies have facilitated a new knowledge and understanding...
Innovative New Developments in Concrete Slipform Paving Equipment for the 21st Century
The Surface Transportation Assistance Act of 1982 gave new life back to the concrete paving industry by bringing a welcomed and necessary increase in the volume of concrete paving work....
Portland Cement Concrete Pavement in the 21st Century
The future of Portland Cement Concrete Paving in the 21st Century holds vast challenges that we as industry must be ready to tackle head on. Looking ahead, we see an even more vital role...
Asphalt Pavements of the Future
There will be major changes in the Hot Mix Asphalt Industry throughout the next decade and into the 21st century. Acquisitions, diversification, SHRP, the emergence of new technologies...
New Concrete and Asphalt Mixes on the Horizon
Significant research is currently 'in progress' which is intended to develop modified or new design methodologies that will result in improved pavement performance....
Building Bridges the Old Way
Cast-in-place concrete bridges built on falsework, particularly post-tensioned box girders, are California's dominant structure type. Factors which have led to the popularity...
