Heuristic Algorithms for Aggregating Rail‐Surface‐Defect Data
(American Society of Civil Engineers, 1994)An optical inspection system has been developed to detect the presence of defects on the surface of rails. The system classifies each 6 in. (15 cm) length of railhead as defective or nondefective and generates large ... -
Level‐of‐Service Analysis of Toll Plazas on Freeway Main Lines
(American Society of Civil Engineers, 1994)Toll collection on freeway main lines can have serious repercussions on freeway operation and management. There are currently no suitable methodologies for level‐of‐service analysis of main‐line toll plazas. To bridge this ... -
Effect of Temperature Changes on Water‐Main Breaks
(American Society of Civil Engineers, 1994)The principles of temperature‐related stresses are discussed. Statistical evidence of temperature effects on water‐main breaks are also presented from the Washington (D.C.) Suburban Sanitary Commission's experience. A ... -
Compacted High‐Gravel‐Content Subgrade Materials
(American Society of Civil Engineers, 1994)Gravelly subgrade materials are frequently evaluated on the basis of laboratory testing on material passing the number 4 sieve size due to difficulties in obtaining representative samples and because laboratory testing of ... -
Human Factors Design Considerations for Variable Message Freeway Signs
(American Society of Civil Engineers, 1994)Variable message signs are used as part of freeway management systems to provide drivers with real‐time information on roadway and traffic conditions. Fiber‐optics and light emitting diodes are two emerging technologies ... -
Characteristics of Trips by Foot and Bicycle Modes in Indian City
(American Society of Civil Engineers, 1994)Walking and bicycling are the two modes predominantly used for travel in urban areas of developing countries, and the location of transport‐related facilities in urban areas thus is influenced by the characteristics of ... -
Reliability Assessment of Continuously Reinforced Concrete Pavements
(American Society of Civil Engineers, 1994)This paper describes a reliability model developed for continuously reinforced concrete pavements (CRCPs) for the Texas Department of Transportation. The model predicts the probability that a CRCP section with a certain ... -

Dynamic Linear Back Calculation of Pavement Material Parameters
(American Society of Civil Engineers, 1994)The dynamic linear back calculation procedure for estimating pavement material properties is presented. Two approaches based on the fitting of the data in the time and frequency domain are described in detail. The time‐domain ... -
Markovian Models for Bridge Maintenance Management
(American Society of Civil Engineers, 1994)The typical infrastructure maintenance decision‐making environment involves multiple objectives and uncertainty, and is dynamic. One of the most commonly used infrastructure models is a Markov decision process (MDP). MDP ... -
Image‐Based Expert‐System Approach to Distress Detection on CRC Pavement
(American Society of Civil Engineers, 1994)The first step in the successful management of pavements is to locate and identify the distress on all pavements that are candidates for maintenance and rehabilitation. This requires the collection of a large volume of ... -
Integrated System to Develop Highway Rehabilitation Projects
(American Society of Civil Engineers, 1994)Highway resurfacing, restoration, rehabilitation, and reconstruction can extend the life of an existing facility. At the same time, enhanced safety can be engineered into a project by making improvements to other features ... -
Effects of Routine Maintenance on Flexible Pavement Condition
(American Society of Civil Engineers, 1994)In recent years, the major efforts of highway agencies have shifted from constructing new facilities to preserving and maintaining existing systems. Maintenance responsibility lies with state and local agencies, and there ... -
Unwanted Legacy of Asphalt Pavement Compaction
(American Society of Civil Engineers, 1993)Compaction of the asphalt mix is that part of the construction process largely responsible for the structural properties and performance of the pavement. By increasing density and reducing air voids, compaction adds strength ... -
Mechanistic Model for Transition Probabilities
(American Society of Civil Engineers, 1994)One important input in a pavement‐management system is the matrix of transition probabilities. A methodology is proposed that employs mechanistic distress submodels for evaluating pavement distresses in terms of fundamental ... -
Temperature Effects on Rigid Pavements
(American Society of Civil Engineers, 1994)An analysis technique, to be used in conjunction with packaged finite‐element programs, is developed for the study of rigid pavements subjected to temperature loading. For illustrative purpose, the pavement is idealized ... -
Probabilistic Delay Model at Stop‐Controlled Intersection
(American Society of Civil Engineers, 1994)Operating conditions at stop‐controlled approaches to highway intersections depend, to a large extent, on the gap‐acceptance behavior of motorists. Several researchers have previously proposed and demonstrated the application ... -
