Comprehensive Monitoring Systems for Measuring Subgrade Moisture Conditions
(American Society of Civil Engineers, 1999)Subgrade resilient modulus is highly dependent on water content, which can vary significantly with a number of environmental factors. Four sites across the state of Tennessee were instrumented with comprehensive monitoring ... -
Posted and Free-Flow Speeds for Rural Multilane Highways in Georgia
(American Society of Civil Engineers, 1999)The National Highway System Designation Act of 1995 repealed the national maximum speed limit. As a result, approximately 70% of the United States has increased posted speed limits to 104.7 km/h (65 mi/h) for select multilane ... -
Side Friction and Speed as Controls for Horizontal Curve Design
(American Society of Civil Engineers, 1999)This paper describes an examination of the relationship between vehicular speed and side friction demand on horizontal curves. Models of speed and friction demand are described. The curve speed model explains the effect ... -
Indiana Lane Merge System for Work Zones on Rural Freeways
(American Society of Civil Engineers, 1999)The Indiana Department of Transportation and Purdue University have been investigating and implementing a novel traffic control system at two-lane freeway work zone entries to reduce the number of aggressive lane changes ... -
Genetic Algorithm Approach to Aircraft Gate Reassignment Problem
(American Society of Civil Engineers, 1999)The aircraft gate reassignment problem occurs when the departure of an incoming aircraft is delayed or a delay occurs in flight. If the delay is significant enough to delay the arrival of subsequent incoming aircraft at ... -

Precision Offset Spray System for Roadway Shoulder Weed Control
(American Society of Civil Engineers, 1999)A precision offset spray system was developed for use by highway maintenance departments for the control of unwanted vegetation in the graded shoulder area adjacent to roadways. The offset sprayer consisted of two fundamental ... -
Effect of Hot-Air Lance on Crack Sealant Adhesion
(American Society of Civil Engineers, 1999)The hot-air lance (HAL) is widely used in crack-sealing work based on the premise that it improves sealant adhesion. The effectiveness of the HAL in promoting adhesion is uncertain, however. Our goal was to measure the ... -
TKUPAV: Stress Analysis and Thickness Design Program for Rigid Pavements
(American Society of Civil Engineers, 1999)An alternative procedure for the determination of critical stresses and the thickness design of rigid pavements is presented. The effects of a finite slab size, different gear configurations, widened outer lane, tied ... -
Measurement of Complex Permittivity of Asphalt Pavement Materials
(American Society of Civil Engineers, 1999)To facilitate applications of road penetration radar and other nondestructive testing technologies on roads, an apparatus was developed for the measurement of complex permittivity of construction materials. The system ... -
Analyzing Freeway Traffic under Congestion: Traffic Dynamics Approach
(American Society of Civil Engineers, 1999) -
Multivariate Analysis of Truck Drivers' Assessment of Work Zone Safety
(American Society of Civil Engineers, 1999)This paper presents multivariate correlation analyses of truck drivers' opinions on speed, hazards, roadway features, and traffic control devices in work zones (WZ). About 90% of truck drivers considered the WZ to be more ... -
Use of Multicriteria Methods for Assessment of Transport Projects
(American Society of Civil Engineers, 1999)This paper attempts to consider some key elements of the transport assessment process in order to present and compare the most commonly applied multicriteria methods to be used in the assessment of transport projects. This ... -
Sensitivity Analysis of Computer Models: World Bank HDM-III Model
(American Society of Civil Engineers, 1999)A problem often arising in engineering applications of computer models is to determine the importance of each data item in the large pool of required input factors. This paper explores a statistical approach for investigating ... -
Simulating Performance Impacts of Bus Lanes and Supporting Measures
(American Society of Civil Engineers, 1999)This study used the TRANSYT-7F simulator to examine changes in performance measures of through buses and adjacent traffic following the introduction of reserved lanes in an urban arterial. In addition, the TRANSYT-7F ... -
Analysis of Engineering Characteristics of Pavement Deflection Trends
(American Society of Civil Engineers, 1999)This paper describes analysis of pavement deflection data collected by the Transport Research Laboratory at two experimental road sites in England during 1960–1985. Measurements of Benkelman beam deflections together with ... -

State of the Art of Highway Geometric Design Consistency
(American Society of Civil Engineers, 1999)Achieving highway geometric design consistency is an important issue in the design and evaluation of rural highways to attain smooth and safe traffic operation. This paper presents a comprehensive literature review of ... -
Alternative Aircraft Loading Index for Pavement Structural Analysis
(American Society of Civil Engineers, 1999)The most common practical way to simplify the structural analysis of airfield pavements is the use of equivalent single wheel load models instead of the actual gear of the aircrafts. As the accuracy and reliability of these ... -
Measurement of Water Content in Portland Cement Concrete
(American Society of Civil Engineers, 1999)Warping of portland cement concrete (PCC) pavements is the result of temperature and/or moisture gradients in the pavement structure. So far, the focus has been on studying and modeling temperature gradients caused by the ...
