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...

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)...

Finite Element Analysis of Reinforced Concrete in Japan and US: Introduction and Overview
The finite element method of analysis now provides the engineer with the capability to analyze very complex structural systems in a much more realistic manner including geometry and support...

Constitutive models
The constitutive models used in the finite element analysis of reinforced concrete structures are presented from a number of different perspectives. The first part of this chapter presents...

Fracture Mechanics
This brief report, prepared by ACl 447 Subcommittee 2, reviews recent advances in finite element modeling of fracture and damage in concrete structures. The fundamentals of the fracture...

Reinforced Concrete
Recent developments and procedures used to model reinforced concrete using finite element analysis are summarized. Special emphasis is placed on the results of a survey of papers published...
