Mechanistic Design Models of Loading and Curling in Concrete Pavements
Determination of the critical bending stress at the edge of a concrete pavement due to individual and combination effects of wheel loading and thermal curling is very crucial to any mechanistic...
Mathematical Modeling of Airport Pavements
Theories for analyzing rigid pavements are presented. The emphasis is on the choice of the proper models for the pavement and for the subgrade, and on the correct mathematical formulation...
Unified Constitutive Model for Airport Pavements
A unified constitutive model that allows for significant behavioral characteristics of materials and interfaces in airport pavement is implemented in a nonlinear finite element procedure....
ICAO's ACN-PCN Method and Aircraft-Pavement Interaction
Multi-wheel gear assemblies of future aircraft are not compatible with pavements rated in the ACN-PCN system given by the International Civil Aviation Organization (ICAO). The Aircraft...
Reliability-Based Analysis and Design of Flexible Airfield Pavements
This paper illustrates, a new reliability-based procedure to analyze existing pavements and design new pavements that is being developed by the U.S. Air Force. The procedure uses a rigorous...
Pavement Design Considerations for Heavy Aircraft Loading at BAA Airports
BAA operates seven airports in the United Kingdom. Two of them, Heathrow and Gatwick, handled 61 million passengers in 1991 with 543,000 air transport movements, 25% by wide-bodied aircraft....
Airfield Pavement Structural Evaluations, Current Practice and Future Needs
The United States Air Force's pavement evaluation teams have to be able to go quickly anywhere in the world to evaluate an airfield pavement's structural capability. A combination of non-destructive...
A Novel Approach to Develop a Performance Based Test for Rutting of Asphalt Concrete
Asphalt concrete consists of compacted granular aggregates mixed with viscoelastic asphalt cement. The predictive phenomenological models had limited success in explaining the origin and...
Durability of Asphalt Mixture
Five asphalts were used in a laboratory testing program to establish a relationship between mixture properties and the binder properties. These five asphalts were used to make Florida...
Lime Treatment of Asphalt Mixtures in Improving Resistance to Moisture
Airport flexible pavement is susceptible to moisture damage. Lime treatment of asphalt pavement is considered to be an effective method in improving resistance to moisture. It has been...
Densification of Asphalt Pavements by Traffic
Since asphalt pavements rut when the voids are filled with asphalt (and voids can become filled by traffic densification) the voids that develop under traffic are vital to any mix design...
Resin Modified Pavement in Airfield Applications
The resin modified pavement (RMP) is a composite paving material that combines the flexible characteristics of an asphalt concrete (AC) material with the durability of a portland cement...
Ft. Campbell Airfield Emergency Reconstruction
The air deployment from Fort Campbell, Kentucky to Saudi Arabia in support of Operation Desert Storm in the summer and fall of 1990 involved several hundred C5 and C141 aircraft loaded...
Portland Cement Concrete Apron Pavement Design Study for King Fahd International Airport in Saudi Arabia
The Federal Aviation Administration (FAA) Advisory Circular 150/5320-6C used for design of portland cement concrete (PCC) pavements for airports does not account for the site-specific...
Evaluation of a Large Aggregate Asphaltic Layer in an Airside Pavement
A new analytical method of designing large aggregate asphalt mixes (LAM) was used to design a thick asphalt base layer for an aircraft taxiway. The results of an analysis on the material...
North Ramp Pavement Evaluation/Rehabilitation?Houston Intercontinental Airport
The North Ramp at Houston's Intercontinental Airport is approximately 23 years old and serves Terminals A and B and also serves as a primary taxiway. Prior to having the new international...
Recycling Concrete and Asphalt Pavements Rehabilitation of Runway 18R-36L Orlando International Airport
The subject project consisted of reconstructing an air carrier runway utilizing a concrete keel section with asphalt overlays along the runway edges. Associated taxiways were rehabilitated...
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...
