Georgia's Low-Cost Approach to Rehabilitating Concrete Pavements
A six step approach to rehabilitating concrete pavements is described. The six steps are: (1) Slab stabilization; (2) slab replacement, where necessary; (3) repair of spalls; (4) resawing...
Pavement Management Systems: Selecting Maintenance Priorities
Realization of the need to maintain a safe, serviceable network of highways in the US has led to the development of a systematic, consistent procedure for managing resources necessary...
Nondestructive Testing Cuts Runway Rehab Costs
Nondestructive testing of an asphalt overlay of a crosswind runway at Kansas City International Airport not only reduced construction costs and runway downtime, but proved that only the...
Fiber-Reinforced Concrete Proves Worth for Airport Pavements
Laboratory and field tests indicate that fiber-reinforced concrete has higher flexural and tensile strength, higher impact resistance, and improved resistance to spalling and joint deterioration...
Orlando International: Airport of the 21st Century
The latest technology in airport design from the apron overlays to the terminal itself was incorporated at Orlando International, the nation's fastest growing airport. Now...
Fiber Reinforced Concrete
In the past 10 years or so, concrete reinforced with fibers one or two inches long has begun to be used, first on a demonstration and experimental basis, then in major everyday applications....
Sulfer Extended Asphalt
Since the 1973 oil embargo, the Federal Highway Administration has researched and promoted the experimental use of a new pavement binder, sulfur-extended asphalt (SEA). In SEA paving mixes,...
Value Engineering Cuts Highway Costs
The Oregon State Highway Department's experimental Value Engineering team examined over 40 highway projects in a search cost savings without sacrificing quality. While the...
Concrete-pavement Recycling could Slash Rehab Costs 30%
During the past few years, the recycling of highway pavements, especially asphalt pavements, has been in the news. Yet one promising development has drawn little attention: the recycling...
Mix Design Formulas for Recycled Hot-Asphalt Plant Mixtures
The design of recycled asphalt paving mixtures is compounded by the amount of asphalt and its properties in the reclaimed asphalt pavement. Formulas are presented for proportioning the...
Bicycle Transportation
A Civil Engineer's Notebook for Bicycle Facilities
The planning and design of bicycle facilities are examined, with the facilities divided into these topics: pavements, drainage, traffic controls, amenities, lighting, parking, landscaping,...
Pavement Recycling Catching On
Sparked by rising prices of asphalt, aggregates, energy, and construction labor, and plagued by a decline in the real dollars available for highway and road maintenance, many highway departments...
1979 International Air Transportation Conference
The current state-of-the-art and future trends in air transportation are discussed. The current state of knowledge in practice and research, and communication between designers and users...
Top Highway Problems: Finance and Maintenance
The nation's highway departments say their number one problem is inadequate funds. Congress and the Federal Highway Administration are worried that, due to inadequate highway...
A Cheap Solution to Pollution from Combined-Sewer Overflows
Every time it rains, the surface waters of many of the older communities around the U.S. are polluted by a mixture of sanitary waste and stormwater. The problem: when the community sewers...
Transportation Engineering Research Needs
In June 1979 a workshop on Civil Engineering Research Needs was convened by the National Science Foundation and ASCE. Of 10 subfields into which civil engineering was split, one was transportation...
The Place of Land Treatment of Wastewater in Today's Society
Land treatment of sewage can be a viable alternative to secondary and/or tertiary in-plant treatment. Depending on local conditions, overland-flow, low-rate, or high-rate systems, or a...
Full-Depth, Full-Width Design, and Prestressed Concrete Pave the Way for Arizona's Highways
In an attempt to resolve design problems of Arizona's non-reinforced portland cement concrete pavements, a series of test installations are being made involving a comparison...
Newark Airport Pilots Cost-Saving Runway Paving Concept
The NYC Met Section nominee for the 1978 Outstanding Civil Engineering Achievement Award was the expansion of Newark International Airport. The $200 million redevelopment included a new...
Reef Runway is First in Airport Design
The Reef Runway Project of Honolulu International Airport constructed on a coral reef, provides approximately 765 acres of new land for the 12,000-ft-long runway with its associated taxiways...
