On the Fatigue Loading for Local Components
Fatigue provisions in the North American Codes for design of highway bridges may not be applicable to the design of local components which are subjected to high axle overloads and dynamic...

Live Load Models Based on WIM Data
The objective of the paper is to present the results of weigh-in-motion (WIM) measurements carried out in Michigan. Selected bridges were instrumented and truck weights and axle configurations...

Pile Installation and Testing at Ningbo Port, China

Design of Marina Replacement Facilities
A majority of the waterfront design projects within the State of California are for the replacement of existing facilities since the densely populated shoreline areas are already heavily...

Pre-Compression of Concrete Breasting Dolphins Solves Construction Problem
A roll-on/roll-off ferry terminal was built in Quincy, Massachusetts in 1989 as part of a marine transportation system to support construction of the sewage treatment facilities proposed...

West Point Temporary Construction Dock
The West Point temporary construction dock is designed to provide construction access for the West Point treatment plant project located in Seattle, Washington. The dock plays a major...

Historic Seawalls of the Boston Harbor, Massachusetts Region: Evolution, Construction and Repair
The earliest seawalls in the Boston region were of crib construction. Cobb cribs had an open framework and could readily be floated into position and sunk with rock from local sources....

Two-Dimensional Hydraulic Analysis of the Owensboro Bridge and Approaches
The Kentucky Transportation Cabinet, Department of Highways, is working with the Indiana Department of Transportation and the Federal Highway Administration to plan, design, and construct...

Probability of Bridge Failure Due to Pier Scour
Methods have been presented for computing the probability of bridge failure due to pier scour either using a maximum scour depth model or a time-dependent model. The probability of failure...

Seattle Swings Again
The 1992 Outstanding Civil Engineering Achievement Award went to a bridge that the experts said couldn't be built�a concrete segmental box girder swing bridge with twin leaves...

OCEA, American-Style
A truly All-American contingent, the nominees for this year's Outstanding Civil Engineering Achievement award span the continental U.S., Alaska and Hawaii. The scope of the...

Building Better Bridges: Concrete Vs. Steel
The authors debate the merits of concrete segmental and steel bridge design and construction based on five criteria: initial and life-cycle costs; structural advantages; durability; construction...

Durability Failure of a Concrete Block Port Pavement
A concrete block port pavement began showing distress after 7.5 years of use. Initial repair attempts found extensive areas of deterioration. The concrete blocks were cracking, spalling,...

Investigation of a Concrete Blistering Failure
During construction of a concrete pavement at a military airfield, numerous small blisters formed on the concrete surface behind the slipform paver and were filled by the contractor using...

Standard Methodologies for the Forensic Investigation of Pavements
The high costs of new construction have made the preservation and restoration of existing pavements an attractive alternative to replacement structures. Existing pavements that are to...

An Airfield Pavement Forensic Analysis: Cairo East Air Base
The US Army Engineer Waterways Experiment Station (WES) was requested by the Middle East/Africa Projects Office in April 1989 to provide technical assistance in analyzing an unstable asphalt...

The Role of Nondestructive Testing in Assessing the Infrastructure Crisis
At present the role of nondestructive testing in the evaluation of infrastructure deterioration is an extremely limited one. In the Author's experience this is, in part, due to a reluctance...

Use of the Break-Off Method for the Evaluation of High Performance Concrete
The Break-Off test is one of the recent developments for testing in-place concrete strength. This research was undertaken to investigate the reliability of the Break-Off test as a measure...

Principles of Infrared Thermography and Application for Assessment of the Deterioration of the Bridge Deck at the Zoo Interchange
This paper details the principles of infrared thermography from the underlying theoretical considerations to the physical constraints involved with performing the test. Infrared (IR) thermography...

The SHRP-LTPP Asphalt Resilient Modulus Pilot Study
A SHRP asphalt concrete resilient modulus pilot study was initiated to provide important supplemental information related to the AC Mr program. Initially,...
