Application of Digital Image Processing in Morphological Analysis of Geotextiles
Geotextile filters are rapidly replacing graded granular filters in dams, landfills, edge drains, and retaining walls. The design of these filters requires morphological information about...
Application of Radar Imaging Techniques to Concrete
Wideband radar imaging techniques have the potential of being a powerful tool in detecting steel reinforcing bars and delaminations inside concrete. The success of the method as a nondestructive...
Machine Vision Based Traffic-Adjusted Intersection Signal Control
This paper describes some of the available machine vision systems and how they can be effectively used for traffic control at an intersection. A set of rules have been defined which make...
Ground Penetrating Radar: Images of Subsurface Characteristics
Ground penetrating radar has not been widely used for subsurface exploration in Civil Engineering. This paper describes the experimental setup used to explore ground penetrating radar...

A number of imaging products have been developed for civil engineering applications. This paper attempts to survey various image processing applications in civil engineering up to date....
Computer Vision Techniques for Comparing Laser Doppler Velocimeter Scans of a Vibrating Plate to Analytical Plate Modes
Computer vision procedures were applied to velocity images of a vibrating square steel plate. A scanning laser Doppler velocimeter (LDV) measured the images of low frequency resonant operating...
Image Enhancement: Application to Geotomography
Image enhancement complements geotomographic reconstruction in the rendering of better images. In this paper, available image enhancement techniques are reviewed. Emphasis is given to...
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...
Image Analysis Applied to Geotechnical Engineering
Application of scanning electron microscope and image analyzer to the quantification of grain morphology and microfabric of aged sands is briefly reviewed. Relationships of morphology...
Finite Element Analysis of Slabs-on-Grade Using Higher Order Subgrade Soil Models
Incorporation of the two-parameter, Kerr and Zhemochkin-Sinitsyn-Shtaerman subgrade models into finite element code ILLI-SLAB is described. The two conventional idealizations, namely the...
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....
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...
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...
