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...
Benefits From Improved Management of Pavement Facilities
Effective management of pavement facilities can provide several benefits both the agency and the travelling public over the long term. The benefits achieved from improved rehabilitation...
Algorithm for Crack Detection in Automated Pavement Analysis
This paper summarizes recent research in various algorithms for detection of pavement cracks. The most successful algorithms use a digital filter to obtain an approximation of the principal...
A Graphics-Based System for Urban Roadway Management
This paper describes a graphics-based system for urban roadway management. The main objective of the system is to select the cost effective maintenance and rehabilitation (M&R)...
Exploration of Ground Penetrating Radar for Railroad Tie Maintenance Scheduling
Assessment of railroad ties for replacement is currently performed by visual inspection. This paper describes a method of automated tie assessment using ground penetrating radar (GPR)...
Highway Maintenance and Integrated Management Systems
Maintenance management systems were among the first applications of rational management principles and the (then) the new technology of computers to highway operations. Recent changes...
TRACK(1.0): A Railroad Track Design and Evaluation Computer Program for Work Planning and Budgeting
This paper describes TRACK, a track structural analysis method and computer program developed by the U.S. Army Construction Engineering Research Laboratories. TRACK is a program for evaluating...
TRACS: A Tool for Track Infrastructure Management
TRACS (Total Right-of-way Analysis and Costing system) combines engineering models with life-cycle costing techniques to estimate track maintenance and renewal costs as a function of track...
An Integrated Design/Construction Research Program for Infrastructure Rehabilitation
The quality of America's infrastructure today is barely adequate to fulfill current requirements, and sufficient to meet the demands of future economic growth and development. This serious...
An Integrated System for Pavement Management
This paper describes the process of developing an integrated computerized pavement management system (PMS) for the New York State Thruway Authority. The process evolves around the integration...
Evaluation of Two Automated Thresholding Techniques for Pavement Images
Thresholding of pavement images is an important step towards the design of an automated pavement crack detection system. However, traditional automated thresholding techniques generally...
Maintenance Management of Power Transmission Lines
An adb-based maintenance management system, KUHA, was developed in Finland to enable more efficient maintenance of power transmission lines. The system is used for strategic planning in...
Planning Maintenance and Rehabilitation Activities for Local Railroads
This paper presents a structured approach for planning annual and long range (multi-layer) maintenance and rehabilitation (M&R) activities for local railroads. A method is presented...
Reliability Assessment of Concrete Pavement Sawing
Traditional concrete pavement design sometimes realize on qualitative decision based on experience, with concrete pavement sawing operations representing a specific case in point. presently,...
Pavement Network Level Management Using Micro PAVER
This paper presents pavement network level management using Micro PAVER with emphasis on pavement condition prediction modeling and annual and long range work planning....
Mitigation of Excessive Wastewater Infiltration/Inflow Effects for US Army Installations
Wastewater collection system on military installations require periodic maintenance and repair, and occasionally upgrading. Deterioration of wastewater systems enables the entry of extraneous...
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...
Digital Imaging as a Design Tool
On most engineering projects, schematic drawings offer a technical representation of a structure to clients. For staff or the public who are not technically knowledgeable, though, schematics...
Treating Uncertainty in the Design of Horizontal Curves
A model based on expected total cost minimization approach is developed for determining optimal horizontal curvature for highway sections. Expected total cost is defined as the sum of...
Aesthetics in High Speed Rail Projects
Aesthetics is critical to the public acceptance and quality of the experience of a high-speed rail system. Social, functional, visual, kinetic, and symbolic aesthetics have specific design...
