Interactive Digital Image Feature Analysis as Applied to Cement and Concrete Microstructural Investigations
A novel procedure involves interactive chemical image analysis of separable features in the backscattered image. In this procedure a backscatter image is acquired by the image analysis...
Application of Digital Images and Processing for As-Built Construction Drawings
The production of as-built drawings is a labor intensive activity that often provides the facility owner with inaccurate or incomplete final drawings. This paper briefly reviews work accomplished...
A Constructability Lessons Learned System for Infrastructure Rehabilitation Using Digital Image Processing
Due to the complex nature of many infrastructure rehabilitation projects, there is a strong need for design/construction integration, and more specifically, the application of strong constructability...
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...
Newark International Airport APM: A Progress Report
This paper presents an overview of the progress of the Newark International Airport APM project, emphasizing facility design and construction....
Automated Guideway Transit to Provide Access to New York City Airports
The Port Authority of New York and New Jersey is currently addressing the issue of airport access in a multi-faceted manner. Besides several transit system management measures, the Aviation...
Closing the Gap: Transit Revenue Opportunities
The LandEagle Project is based on the premise that public transit systems can be financially self sustaining; an idea usually greeted with wonder and amazement. This paper explores methods...
Initial Planning and Implementation of the Telluride Gondola Transit System
Construction on the first phase of a gondola transit system began in the summer of 1992, with the goal of connecting the town of Telluride, Colorado with the Telluride Mountain Village,...
