Evaluation of Runway Roughness for Fighter Jets
A new roughness evaluation procedure is needed, especially, when dealing with modern fighter jets. To this end, a comprehensive pilot attitude survey was conducted in Israel in order to...
Heavy Aircraft Damage to Rigid Airport Pavements
A theoretical solution is presented for the damage caused by heavy aircraft at the transverse joints in a rigid airport pavement. Large stresses in the subgrade generate significant permanent...
Evaluation of Elastic Layered Theory for Airfield Pavements, Using Nondestructive Testing and In-Place Response Measurements
Airfield pavement deflections measured under actual aircraft loads were compared to predictions based upon elastic layer theory and moduli backcalculated from failing weight deflectometer...
Measurement and Analysis of Airside Pavement Roughness at the Dallas/Fort Worth International Airport
In May 1990, Dallas/Fort Worth International Airport management contracted with Harding Lawson Associates to implement a pavement management system for that airport. In this implementation,...
Use of Porous Friction Course to Retard Reflection Cracks in Bituminous Overlays
Porous Friction Courses (PFC) are open-graded, high air void, bituminous mixtures that are applied to pavement surfaces to improve skid resistance. In 1989, PFC was used as an interlayer...
Evaluation and Overlay Design of Airport Pavements
Heavy weight deflectometer (HWD), a heavier version of the falling weight deflectometer, enables detailed evaluation of airport pavements to be performed using a rapid a non-destructive...
Rehabilitation of Runway 4R-22L at Chicago's O'Hare International Airport
This paper describes the systematic process that was used to develop a rehabilitation strategy for the busiest runway at O'Hare International Airport. Any rehabilitation alternative that...
Use of Surface Treatments on Airport Pavements
Asphalt is generally used as the surfacing for flexible airport pavements with airline passenger jet aircraft. In Australia and its neighbouring territories, surface treatments (seals)...

Vietnam: Worth Looking Into
If it is to enter the world economy, let alone play catch-up with the booming economies of some of its neighbors, Vietnam requires massive numbers of infrastructure projects: roads, bridges,...
So Much Pavement, So Little Time
At its most basic, pavement management requires taking inventory of a pavement network, doing a condition assessment, setting up a database, then synthesizing the data collected for an...
Design of the Boney Falls RCC Emergency Spillway
The Boney Falls Emergency Spillway was designed as a mass roller compacted concrete structure. Alternative designs considered include a fuse plug, lowering the embankment and paving with...
The Roads Ahead
In 1990, 37 states spent almost $50 million on highway pavement crack sealing, according to researchers at the Strategic Highway Research Program (SHRP). In the near future, a robotic...
Variational Solutions of the Von Karman Plate Theory Based on a Mixed Formulation
A mixed formulation, involving the transverse deflection w(x,y) and the in-plane stress function F(x,y) as the unknown variables, will be used to obtain improved variational solutions...
A New NDT Device for Comprehensive Pavement Maintenance (Theoretical Aspects)
A new nondestructive testing (NDT) device is being developed to detect some precursors to pavement distress. The principle of operation of the device is based upon the generation and detection...
Fine Tuning the Airfield: The New Denver International Airport
This paper discusses airfield layout considerations that have been incorporated into the design of the new Denver International Airport (DIA). These concepts include some unique provisions...
Characteristics of High-Speed Runway Exits for Airport Design
This paper addresses some of the geometric design and operational characteristics of high-speed runway exists. Lateral and longitudinal runway constraints limiting the use of high-speed...
Design Considerations for Multi-Wheel Aircraft
The available test data for performance of flexible pavements were analyzed using the Boussinesq and elastic layered theories. It was shown that strain criteria could be developed for...
Studies Related to Aircraft/Runway Friction Performance
Gaining a better understanding of the many factors influencing the tire/runway friction interface is the aim of several ongoing NASA Langley research programs. Results from studies conducted...
