SHRP Deformation Test—Asphalt Mix Tests and Analysis Systems
From analyses of existing information on the permanent-deformation characteristics of asphalt/binder-aggregate mixes, as well as the development of permanent deformation in pavement structures,...

Structural and Hydrologic Considerations for the Flooding Reservoir Operations of Jiguey Dam, Dominican Republic

Cabinet Gorge Arch Dam Finite Element Analysis

Nondestructive Testing Role in Repair and Rehabilitation of Concrete Structures
Nondestructive testing (NDT) methods are increasingly being used to assess the condition of structural concrete. The paper discusses applications of NDT methods for forensic investigation...

Reliability-Based Analysis and Design of Flexible Airfield Pavements
This paper illustrates, a new reliability-based procedure to analyze existing pavements and design new pavements that is being developed by the U.S. Air Force. The procedure uses a rigorous...

Evaluation of Dilatometer Method to Determine Axial Capacity of Driven Model Pipe Piles in Clay
The flat Dilatometer (DMT) provides a unique approach to estimate the effective stress axial capacity of driven displacement piles in clay. An investigation using this approach was performed...

Osmotic Suction as a Valid Stress State Variable in Unsaturated Soil Mechanics
The hypothesis of the research being presented is that the osmotic suction of soil pore fluid is an independent, valid stress sate variable for unsaturated soils. A review of concepts...

Modelling the Behaviour of Compacted Soils
Predictions based on a recently developed model for unsaturated soil behaviour have been compared with some results of two experimental programs on compacted soils recently published in...

Elasto-Plastic Volume Change of Unsaturated Compacted Clay
Isotropic compression tests were performed on samples of unsaturated compacted kaolin in a modified triaxial cell that allowed separate control of pore water pressure and pore air pressure....

One and Three Dimensional, Three Phase Deformation in Soil
An initially saturated soil exhibits two distinct deformation patterns as it drys. First, it deforms vertically until the soil begins to drain. Secondly , it deforms laterally as well...

Stabilized Active Clay by Sand Admixture

Passive Acoustic Emission for Quantitative Evaluation of Freeze Thaw and Alkali Aggregate Reaction in Concretes
Several experiments are reported in which the progression of freeze thaw (FT), alkali-aggregate reaction (AAR), and internal cracking caused by mechanical loading were monitored using...

Damage Assessment in Concrete Using Acoustic Emission
An acoustic emission (AE) is a localized rapid release of strain energy in a stressed material. This energy release causes stress waves to propagate through the specimen. These acoustic...

Study of Three Dimensional Crack Tip Location of Mortar by Acoustic Emission
Plain mortar specimens were tested under three-point bending. Experimental variables include the width of the specimen and the notch-to-depth ratio. The experimental results of 12 specimens...

Geomechanics of Subsidence Due to Pumping of Groundwater
In this talk we describe a nonlinear theory for the classical problem of pumping of groundwater from a layered soil. The model soil system consists of three horizontal layers where a very...
