Perception and Control for Automated Pavement Crack Sealing
Pavement maintenance is a major transportation engineering activity that has seen only partial mechanization and virtually no automation. Crack sealing is a typical maintenance task in...
Magnetically levitated vehicle technology, maglev, serves as a potential solution to ever increasing transportation demands. Though interest in maglev appears to be increasing, an appropriate...
Rail Replacement Planning: A Knowledge System Approach
Replacer is a knowledge system that provides a consistent means for developing plans for rail replacement. It was developed, tested, and evaluated in cooperation with Burlington Northern...
Operation and Maintenance Plan for Marinas
A operation and maintenance (O&M) plan for marinas is presented to describe the process and establish basic parameters that can be used as guidelines to more comprehensive site-specific...
Organisation Structure and Control
With today's rapidly changing world economies and a variety of other pertinent factors, the euphoria of the past few years is fast dwindling and a professional approach in...
Prediction of Airfield Pavement Responses Using Transfer Functions
A methodology is presented which will aid in the evaluation and maintenance of airfield pavements. Predictions of an airfield pavement's behavior to multiple types and magnitudes...
Results of the 1989 ASCE Airfield Pavement Survey
In November of 1989, the American Society of Civil Engineers Airfield Pavement Committee sent out questionnaires to airfield pavement engineers across the country to assess the most recent...
DFW Pavement Management System Implementation
Dallas/Fort Worth International Airport is implementing a comprehensive pavement management program to assist them in identifying and prioritizing maintenance, rehabilitation and reconstruction...
Manhole Rehabilitation
Manholes are frequently the forgotten element in infrastructure renewal. When they aren't properly maintained they allow excess water into the sewer system, and structural...

Durability and Damage Tolerance Evaluations of Jet Transport Structures
Many design considerations are involved in ensuring structural integrity of Boeing jet transports, which have common design features validated by extensive analyses, tests, and service...
Strategies for Bridge Inspection Using Probabilistic Models
This paper describes the application of probability analyses in planning an inspection program for highway bridges. When damage in the form of fracture and cracking is the major concern,...
Analysis of Bridge Maintenance and Rating Procedures
In the United States, bridges are routinely rated to evaluate their existing conditions. The formula used to evaluate bridges is called the Sufficiency Rating Formula. The formula uses...
Bridge Live Load Models
This paper describes the analysis of weigh-in-motion data and the conclusions drawn. Statistical distributions of the effects induced in typical bridges due to single vehicle events are...
Reliability-Based Bridge Life Assessment
Fatigue considerations have usually entered design codes as a secondary consideration and often under the guise of serviceability limits. Most engineers felt if the maximum stress ranges...
Reliability Assessment and Reliability-Based Rating of Existing Road Bridges
A practical reliability model for the safety assessment and rating of existing R.C. bridges are developed by explicitly incorporating the degree of deterioration and damages based on available...
The NOVA SPAN Bridge System
The NOVA SPAN Bridge concept provides the basis for the design and construction of a new variant in the field of bridges and culverts which, in its performance and operation, incorporates...
Advances in Trenchless Sewer System Reconstruction
The new developments and refinements in trenchless reconstruction technologies now permit total sewer system rebuilding of collectors, interceptors, manholes, service laterals, and force...
Case System and Ancillary Equipment Maintenance
Per-shipment activities, incidental maintenance, repair, and routine maintenance for Federal Waste Management System (FWMS) casks and ancillary equipment and responsibility for those activities...
An Astronaut Positioning System for Space Station Assembly and Maintenance Support
Large space structures require special systems to support assembly, operations, and maintenance. These systems must be designed to support many tasks throughout the life of the space facility....
