Selection of Performance Levels for Longitudinal Barriers
There is a demand within the highway community for multi-service level safety features, including traffic barriers. The need has become more acute in recent years as revenues decline and...
Performance of Highway Traffic Barriers
This paper describes an investigation of traffic barrier performance in New York State. A one-year sample of all traffic-barrier accidents in the state was obtained from Department of...
Hazardous Events After Redirectional Collisions
The potential for hazardous events occurring to vehicle occupants after a redirection from a longitudinal barrier has not been adequately addressed. Very few studies are available which...
Assessment of Safety Impacts of Highway Projects
In this paper the safety impact of highway improvement and maintenance activities is examined in terms of accident reduction potentials of these activities. There are three causes of accident:...
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'...
Innovations in the Design of Electrical Transmission Structures
New concepts are being advanced for the design of electrical transmission structures. The papers in this book cover the following: weather-element loading conditions, structural options,...
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...
Berth 5-6 Pavement Performance: Port of Oaklan
In 1978 the Port of Oakland commenced a project to demolish the old Berth 5, 6 & 7 break bulk sheds, portions of the wharves, and the warehouses behind, and to construct container...
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)....
Construction Materials for Civil Engineering Projects
The materials of construction in use today have grown in number, increased in complexity, expanded in application and multiplied in utilization over those in use just a short time ago....
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...
Parking Lot Gets White Top
The many-acre parking lot at the Valley Fair Mall shopping center in Salt Lake City, Utah is described. In 1985 the asphalt pavement was overlaid with concrete, making it one of the relatively...
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...
Winter Highway Construction
The purpose of this paper is to describe a study of the feasibility of constructing highways in the wintertime in cold regions. The study, sponsored by the Alaska Department of Transportation...
Truck Weight Enforcement on a WIM
Pavements on interstate highways and other major truck routes are deteriorating faster than predicted. The cause is largely the larger-than-predicted number of the heaviest, 5-axle trucks....
