Highway Capacity Manual Revisited
The forthcoming third edition of this manual of highway and traffic engineering, due in 1985, will significantly change how highway capacity is analyzed. Of the edition's...
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...
Transportation Brokerage in a Bi-State Area
Transportation brokerage is a coordinated management approach to meeting transportation consumer needs with existing transportation providers. In doing so, brokerage fosters increased...
Policy Analysis Implications of Four Cogent Transportation Topics
Using a goal-group policy-analysis scheme and from his experience on Capitol Hill, the author documents his observations on the cogent transportation topics facing the United States in...
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...
Preparation of Equipment for Cold Regions
An overview of equipment required to support arctic construction is presented. Special features which have been incorporated into standard equipment designs are explained. Also presented...
Australian Coal Terminal Operates Happily Beside Residential Area
A coal terminal was built in Port Kembla, Australia at a $7.56 cost per metric ton. The port was built for $121 million, $18 million below estimate. It included such innovations as the...
Pipelines in Adverse Environments II
State of the art and future trends in pipeline design, construction and maintenance are reviewed. Specific areas addressed include adverse terrain conditions, river crossings-particularly...
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...
Computer-Aided Drafting in Civil Engineering
Computer aided drafting (CAD) is defined as an interactive computer graphics system suitable for the generation of engineering documentation. The development of CAD is reviewed. The computer...
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,...
Construction Productivity Improvement: How to Get Started
The greatest cost reductions and improvements in speed and efficiency on construction sites have come when management analyzes work methods, administrative and environmental constraints,...
Value Engineering Cuts Highway Costs
