Microcomputer Applications for Pavements
The Federal Highway Administration (FHWA) has been active in exploring expanded microcomputer applications with the goal of improving efficiency and benefits to the public through reducing...

The Use of Microcomputers to Perform Airport Emission Inventories
The authors found the use of LOTUS 1-2-3, a microcomputer spreadsheet package that permitted easy calculation of emissions and easy revision of data for studying options in aircraft types,...

A Pavement Management System for Cities & Counties
A regional agency, a pavement management consultant and six cities and counties in the San Francisco Bay Area have jointly developed a Pavement Management System (PMS) which runs on a...

Costs of Truck Related Highway Damage to Alaska
The cost of pavement damage to the State of Alaska for truck traffic continues to be a very controversial topic. There is no simple answer since this cost is dependent upon pavement strength,...

Survey of Airport Pavement Distress in Cold Regions
The most common pavement problems were associated with non-traffic related phenomena and included pre-existing cracks reflecting through asphalt concrete overlay (in two years or less),...

Stabilization of a Permafrost Subsidence in the Airport Runway at Bethel Alaska
During the construction of the extension to the Bethel Airport runway in 1969, it was necessary to construct a fill across a small gully. The subbase material in the gully contained some...

Reinforced Roads Bridging Voids
A mathematical model was developed to design a pavement section reinforced with a geotextile or related product to span a void. A full scale field test was conducted to verify the model....

A Thermal Analysis of Pavement Thawing
This research focuses on identifying the spring thawing period for the purpose of timing load restrictions on low to medium volume roads in frost-susceptible areas. Cases evaluated include...

Insulation Performance Beneath Roads and Airfields in Alaska
Evaluations of the long-term thermal performance of installations in Alaska for frost heave control have included sampling and testing of the insulations to determine the retained thickness,...

Effects of Lane Width Reduction on Safety and Flow
This research dealt with the issue of lane narrowing as an alternative to pavement widening in providing safety improvements on urban freeways. This study dealt with I-95 in Miami Florida...

Problems of Spectral Analysis in Dispersion Tests
The use of dispersive surface waves and spectral analysis methods is new to the nondestructive testing of airfield pavements. Such tests are to determine whether mechanical properties...

Development of Second Generation Plasticized Sulfur Binders as a Paving Material
Plasticized sulphur is produced when melted sulphur is reacted with selected hydrocarbons to produce polysulfides. These polysulfides help retain a 'polymeric'...

Pavement—An Integral Part of the Terminal as a Container Handling System
A modern container terminal requires extensive areas of paving for stacking and moving containers, the provision of which often proves to be one of the most expensive single items, in...

Pavement Design for a Break Bulk Terminal Yard
This paper discusses the practical application of mechanistic pavement design principles for a proposed 8. 1 ha break bulk cargo storage yard that is part of the Port of Portland's...

Concrete Block Paving for Marine Terminals
This paper describes the application of concrete block pavements to marine terminals. The Corps of Engineers flexible pavement design approach can be modified to provide a conservative...

Roller Compacted Concrete Pavement for Marine Terminals
This paper describes recent intermodal yard paving projects at the Port of Tacoma, Washington which have utilized a relatively new paving process known as Roller Compacted Concrete (RCC)....

Asphalt Pavement Modifiers
Modifiers or additives to asphalt concrete pavements are being researched or marketed by many major chemical firms. Modifiers or additives are used to stiffen the asphalt in hot weather...

Ports '86
Ports '86 had the theme of Innovations in Port Engineering and Development with keynote speakers looking ahead to Port Development in the 1990's. The program...

Construction of Roller-Compacted Concrete Pavement
Roller-compacted concrete pavement (RCCP) is the product of a relatively new concrete paving technology in which a zero-slump portland cement concrete mixture is spread with modified asphalt...

Computer Assisted Pavement
In Rancho Palos Verdes, Calif. a 4,300 ft. long test installation of the Contained Rock Asphalt Mat (CRAM) Pavement System is expected to have a 50 year life. It cost a third less than...
