Recent Developments, Future Needs and Opportunities in Pavement Technology and Management
The Strategic Highway Research Program (SHRP) represents a massive research effort aimed at developing implementable solutions to five well-defined pavement problem areas. Pavement management...
Developments in New and Existing Materials
Materials engineering has emerged as an identifiable professional practice within civil engineering in the past few years. Although materials engineering is not new, the concept that this...
Rating Pavements by Computer
Pavement rating is a necessary and labor-intensive job and one with a high turnover rate of personnel. Also, rating scores are often inconsistent from day to day, or between different...
What Do Pavements Cost?
Life-cycle costing is a rational tool used to forestall problems with highway infrastructure. Currently this tool is still an imprecise one. The Federal Highway Administration has a system...
Vehicle Design Exchange With Other Disciplines
Vehicle Design as one of the eight designated areas of interest or 'disciplines' includes a wide range of interests within itself. It can range from overall vehicle...
Roller Compacted Concrete Pavements in British Columbia, Canada
Roller Compacted Concrete (RCC) pavement is an outgrowth of the traditional cement-treated aggregate base (soil-cement) method of street and highway construction. The major use in British...
Can Management Techniques Solve Pavement Woes?
Cities are increasingly turning to systematic procedures for allocating scare manpower and funds and measuring pavement repair and rehabilitation needs. Many cities have adopted pavement...
Pavement Recycling: Stopgap or Remedy?
Recycled pavements cost less than new asphalt concrete overlays, but no long term data has ratified how recycled pavements' strength and durability compare to virgin material....
Effects of Fines in Gravel Bed Streams Behavior
A model-gravel bed stream is studied in the laboratory. Flow visualization of bedload motion correlates with bursting phenomena near the bed. The bedload variation as a result of the addition...
Prestressed Concrete Pavements: Status Report
Prestressed concrete is cost-competitive with and requires less maintenance than conventional concrete, but acceptance of prestressed pavements in this country has been slow. While Europe...
Asphalt: Great Expectations
A $50 million, five year research program has been proposed for research into asphalt as part of the larger ($150 million) Strategic Transportation Research Study (STRS). The research...
Recent Developments in Pavement Skid Resistance
As pavements wear, they lose some of their skid resistance. This article discusses some of the leading options for restoring a pavement's skid resistance. The possibilities...
Arizona's Statewide Pavement Management System
A pavement management system developed for Arizon's 7400-mile network of highways has resulted in a savings of $14 million in its first year and a forecast savings of $101...
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...
Union Construction is Fighting Back
To meet the threat of open-shop construction, union labor and contractors in several cities around the nation are working together in joint labor-management committees to improve the productivity...
Design of Offshore Pipelines for Ice Environments
Design and installation of offshore pipelines in cold regions requires special care. Low ambient temperatures may cause increased friction losses in oil and gas lines due to wax crystallization...
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...
