Not Your Father's Concrete
A simple mixture of water, aggregate and cement, conventional concrete is environmentally-friendly by nature. But with landfills bloating and hazardous wastes becoming increasingly difficult...
San Francisco CSO
Today, even a light rain can overload San Francisco's combined sewer overflow (CSO) system, sending untreated sewage and stormwater into the bay and ocean. This is especially...
Guidelines for Field Evaluations of Pothole Repairs
Prepared by the Highway Innovative Technology Evaluation Center, a CERF Service Center. This report describes the HITEC evaluation plan for Bondade,...
Impact-Echo Strikes Home
Diagnosing flaws without destroying the structure is the first step to cost-effective repairs. Impact-echo is one of the more successful nondestructive evaluation (NDE) methods that have...
Triumphant Arches
This year's Outstanding Civil Engineering Achievement Award of Merit goes to the Natchez Trace Parkway Bridge in Tennessee, the first precast concrete segmental arch bridge...
Advances in Underground Pipeline Engineering II
The first international conference on Advances in Underground Pipeline Engineering was held in 1985. Some 50 authors and over 300 delegates from 20 countries took part in the presentations...
New Construction Materials Proliferate in Japan
Research and development of new construction materials is extensive in Japan, and many new materials are being used in Japan now. The author analyzes the research environment in Japan,...
More Parking Above
Vertical expansion of six (6) new floors of parking garage on top of four (4) floors of existing structure that was built over three decades ago, adding 155,000 square foot of new structure....
Specifying End Results
Quality of materials and workmanship directly influences the life of pavement, maintenance costs, levels of service and user costs. End result specifications (ERS) make a step towards...
Wider Ride to the Rainbow
Engineers on the project to widen the entrance to the Rainbow Bridge between New York and Ontario let the aesthetics of the Niagara Falls setting dictate their design decisions. The challenge...

Reliability and Response Control of R/C Buildings
A damage model is summarized for the assessment of seismic damage of reinforced concrete structures. The model is to evaluate specific buildings that were damaged in Mexico City during...
Checking Concrete Growth
When the Tennessee Valley Authority built its dams in the 1930s, instrumentation installed in the massive concrete detected a defect that would later cause major problems: concrete growth...
Advancement of Material Handling Technologies for In-Place Asphalt Pavement Recycling
New technologies for asphalt pavement resurfacing are improving dramatically with the advancements being made to related equipment technologies. This paper focuses on the recent developments...
For the Realization of Lunar Concrete
Since most of the raw materials required to make concrete exist in lunar rocks and soils, concrete is considered as one of the most suitable materials for lunar structures. Author's research...
Production of Lunar Concrete Using Molten Sulfur
A study has been undertaken by the authors and supported by NASA to study the feasibility of using lunar regolith with different binders such as molten sulfur, epoxy or hydraulic cement...
Concrete Buildings in Regions of High Seismicity
Structural systems for multistory concrete buildings in regions of high seismicity are reviewed. The suitability and certain practical aspects of the systems are discussed. A Uniform Building...
High-Strength Concrete Columns in High-Rise Buildings
Strength and ductility of high-strength concrete columns were investigated by examining available test data. The results are summarized in terms of load and ductility capacities of columns....
Coupling Translation and Rocking Motions
In the design of concrete block foundations for rotating and reciprocating machines, it is important to avoid resonant conditions. Therefore, accurate determination of the frequencies...
Physical Model Tests of Dolos Impact Stresses
An on-going experimental study to determine impact stresses and static nesting stresses in instrumented large scale model dolosse is described in this paper. Seven dolosse were instrumented...
