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),...
Hot Sand for Improved Traction on Icy Roads
Experiments were performed to determine if heating sand prior to spreading it on icy roads would improve the skid resistance of the road more than cold sanding. Tests were made on a full-scale...
A Laboratory Study of Factors Affecting Wetted Snow Roads
A brief review of the the literature concerning the application of water to the surface of snow roads is presented. It is demonstrated that there is no general agreement on the proper...
The CBR Test Applied to Processed and Compacted Snow
The processes used during the past two decades to improve the snow bear a modest resemblance to conventional flexible pavement construction, thus the field CBR (California Bearing Ratio)...
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....
Characterization of the Dalton Highway Foundation Soils
A case study is presented of the landform-based probabilistic-statistical route geotechnical characterization of natural foundation soils along the Dalton Highway. Landforms were mapped...
Cold Regions Features of the Whittier Access Tunnel
A feasibility study and cost estimate has been prepared for a vehicular tunnel which would form a portion of a highway between the town of Whittier, Alaska and the east side of the Kenai...
Alyeska Reroutes Trans-Alaska Pipeline at MP 200
This paper discusses the 1985 wintertime repair/reroute to the Trans Alaska Pipeline System (TAPS). The rerouted pipe was approximately 4000 feet long and cost approximately 27 million....
Wastewater Plant Cold Weather Operational Problems
A questionnaire survey was conducted at biological wastewater treatment facilities in northern New England. Problems associated with various unit processes, due to cold weather operations,...
Legal Concerns in Cold Regions Engineering and Construction
For a variety of reasons the potential for the imposition of liability and the potential for comparatively large damage claims is greater in cold regions. It is the purpose of this paper...
A Microcomputer CAD System for Seismic Design of Regular Highway Bridges
A microcomputer program to implement the recent seismic design guidelines for highway bridges is described. The methodology was developed by the Applied Technology Council (ATC) and is...
Integrated Design of Concrete Flat Plate Structures
An integrated structural design and drafting system for concrete flat plate floor systems is described. This system provides at a single computer workstation the tools necessary to layout...
Seismic Structural Optimization and Computer Programs
A generic system has been developed for the geometric design of highway retaining walls. Merging the three-dimensional coordinate geometry capabilities of the roadway design system (RDS)...
Tiedback Walls Untie Intersection
The intersection of Gallows Rd. and Arlington Blvd. in Virginia's Fairfax County required separation. Tiedback retaining walls, which required only 18 in. instead of the 18-22...
Spanning Urban Obstacles
Extension of Pittsburgh's Crosstown Expressway is a � mile portion of a massive $500 million urban highway now under construction. The extension is a complex of five roadways...
Scenic Squeeze
Constructing a four-lane dual highway through the 12 miles of Colorado's Glenwood Canyon involves several engineering innovations: cantilevered roadways, unusual retaining...
Transportation Liability and Risk Management
Risk management programs provide an excellent response to the increased exposure of all transportation agencies to tort liability claims. While some actions and responses require resources...
Tort Liability in the Pennsylvania Department of Transportation
During the past decade many have questioned the propriety of the doctrine of sovereign immunity; numerous legal challenges and legislative changes have eroded the doctrine in most states....
Risk Management to Reduce Highway Tort Liability
This paper identifies common risk management techniques and processes. A brief review of tort law is presented along with the specific characteristics of a highway related negligence suit....
