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...
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
