Fiber Composite Warp for Rehabilitation of Concrete Structures

Serviceability of Earth Retaining Structures
Civil Engineers increasingly face decisions concerning the serviceability of existing earth retaining structures. Serviceability limit states describe the functional disruption which occurs...

Durability of Concrete Bridges in Virginia
This paper discusses four major types of deterioration found in concrete bridges: corrosion of the reinforcement, alkali-aggregate reactivity, freeze-thaw deterioration, and attack by...

Construction and Maintenance Decisions for Multi-Unit Deteriorating Facilities
Facilities that deteriorate over time and use can require maintenance or replacement. Selecting among replacement and maintenance alternatives for large systems of deteriorating facilities...

Highway Speed Radar for Pavement and Bridge Deck Evaluation
Radar has been developed as an economical alternative evaluating pavement layer properties and estimating quantities of deterioration in bridge decks. These highway applications are based...

The TM– Railroad Track Management System
The TM$ Railroad Track Management System is designed to increase effective access to track performance data, to forecast the effects of deterioration and maintenance activity, and to formulate...

Infrastructure Condition Forecasting Using Neural Networks
Condition forecasting models are critical components of any infrastructure management system. infrastructure condition assessed through periodic inspections which assign ratings to various...

Transient Performance Model of Asphalt Pavement Deterioration and its Application to Repair Management
The Japanese Ministry of construction has conducted surveys of the pavement surface condition of national highways. This paper describes the evaluation of the performance of asphalt pavement...

Deterioration Models for Highway Bridges
Infrastructure management, especially in case of highway bridges, need a realistic and effective deterioration model in order to provide information on the present and future condition...

The Finnish Bridge Management System
A computer-based Bridge Management system, BMS, was designed in Finland by the Finish National Road Administration (FinnRA) to assist in high level bridge policy, long-term planning and...

Strength Deterioration Behavior of Concrete-Filled Steel Tubular Beam-Columns
Cantilever beam-columns of steel square hollow section with or without filled-concrete were tested under constant axial load and alternately repeated horizontal load to investigate the...

Condition Data Reduction for Pavement Management
A methodology is proposed for the identification of uniformly behaving deterioration regions of infrastructure facilities. Such `homogeneous' regions constitute the basic units that should...

Modification at Hiwassee Dam due to Concrete Growth Problems

Concrete Penstock Leakage, Investigation of Causes and Rehabilitation Options

The Demolition of Mussers Dam

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...

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...

Concrete Surface Treatments—A Selection Guide
Concrete deterioration can take many forms. The most common forms of concrete surface deterioration includes delaminations, spalling and scaling. This deterioration is usually caused by...

Investigation of Concrete at a Middle East Plant
In recent years, reinforced concrete construction in the Middle East has been beset by durability problems. The causes include availability of a limited number of skilled workers, marginal...

Problems With Armor-Stone Quality on Lakes Michigan, Huron, and Erie
The instances of deterioration of armor stone at coastal structures on the Great Lakes result from numerous distinct causes, both intrinsic and extrinsic. However, the proof of specific...
