Highway Pavement Surfaces Reconstruction by Moire Interferometry
The necessary basis for any cost-effective highway and bridge deck pavement management program is reliable, complete and up-to-date information concerning the state of pavement surface....

Design Considerations for Automated Pavement Crack Sealing Machinery
The purpose of this paper is to discuss the numerous considerations for designing automated machinery for the sealing of cracks in pavement. Operational requirements are presented and...

Automated Analysis of Pavement Distress Data
A system model that can be used for the analysis of pavement distress data collected by various visual devices (e.g. photographic film) is presented. The models operate at two levels:...

Measuring Highway Inventory Features Using Stereoscopic Imaging System
The new stereoscopic measurement approach is discussed in this paper. The objective of this paper is not intended to present another new videologging system. Instead, this paper is to...

Subsurface Pavement Structure Inventory Using Ground Penetrating Radar and a Bore Hole Camera
The Pavement Management System (PMS) is now a necessary pavement evaluation tool. The PMS data base has been historically fed with surface inspection data, but increasing demands for accurate...

Flexible Pavement Distress Evaluation Using Image Analysis
A unique combination of image histogram and projection histogram are employed to classify major distress types on flexible pavement. This technique has taken into account the presence...

Aircraft Traffic Mix Analysis: Damage Factors and Coefficients
Historically, traffic mix analyses have been based upon the use of the critical or most damaging aircraft. The damage effects of other aircraft are either ignored or empirically incorporated...

Pavement Design by Elastic Layer Theory
The U. S. Army Engineer Waterways Experiment Station has been developing methodology by which airport/airfield pavements can be designed based on elastic layered analysis for the Federal...

Pavement Design for the New Denver International Airport
Denver International Airport is the first new major U.S. airport in twenty years. Primary airfield elements in Phase I development include 5-12,000 foot runways and 1-16,000 foot runway,...

Joint Spacing for Airfield Pavement
This paper looks at various factors affecting portland cement concrete(PCC) pavement cracking, with special emphasis on the effect of joint spacing on crack development. A rational approach...

The Effects of Runway Roughness on Aircraft Fatigue Life
A computer code developed within the Flight Dynamics Directorate of the Wright Laboratory was used to simulate the dynamic response of heavy aircraft operating on runways with various...

Tactical Aircraft and Airfield Recovery
This article is based on Captain Bahm's Master's thesis and was co-authored by his thesis advisor, Captain Polasek. The article is reprinted from the Airpower...

Runway Roughness Measurement, Quantification and Application: The Boeing Approach
The measurement of runway roughness and the determination of the severity of runway roughness have long been the subject of nebulous discussion and esoteric description. By considering...

Pavement Materials for ASTOVL Aircraft Application
Jet blast impingement on concrete is a problem today and will worsen when the new vectored-thrust aircraft become operational. Ground erosion has already been observed under the auxiliary...

Asphaltic Concrete Performance Under High Pressure Tires
A study was conducted by the USAF Engineering and Services Laboratory to evaluate the rutting effects of high pressure tires on Marshall and gyratory designed pavements. Full scale pavement...

Modified Asphalt Binders for Military Airfield Pavements
This report documents a laboratory-based research effort to determine the effects of asphalt modifiers and alternate binders on asphalt airfield pavements. The modified binders were tested...

Pavement Experiences Indicative of Needs to Consider Design and Specification Revisions
Recent experiences on two airfield paving projects have indicated some problem areas which may warrant further consideration in design manuals and specifications. 1. Construction of the...

Recycling Bituminous Runway Pavement into Aggregate Base Course
The paper discusses the development of recycling existing bituminous runway pavement by pulverizing into aggregate base course. To best explain the design, construction procedures and...

A Concrete Alternative to Runway Reconstruction
Faced with the prospects of losing commercial air service for up to two months, the Charleston County Aviation Authority, the Charleston Air Force Base and their engineers had to look...

Alternative Airfield Pavement Quality Control
In recent years, the cost of maintaining quality control during airfield construction projects has concerned airport operators and engineers alike. This paper addresses the possibilities...
