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...

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....

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...

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...

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...

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...

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...

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...

Automated Design of the Steel Box Girder Guideway for the Kuala Lumpur Downtown People-Mover
Design of the Kuala Lumpur (KL) Downtown People-Mover had to be accomplished on a fast-track schedule. The system contractor assembled a team of experts from North America and Malaysia...

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...

Time-Dependent Behavior
This paper is a report of the material presented at the International Workshop on Finite Element Analysis of Reinforced Concrete, Session 4 - Time Dependent Behavior, held at Columbia...

Computational Aspects
In the past, two distinctly different approaches - smeared and discrete failure models have been adopted to describe failure mechanisms in plain and reinforced concrete structures. Although...
