The Load Factor
Spangler's load-factor formula for projecting conduits is generalized to all cases of buried rigid pipe, whether in trenches or under embankments; this is in accordance with the analytical...

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

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...

Digital Image Techniques for Volume Change Measurements in Triaxial Tests
This paper presents an innovative technique that has been used for measuring the volumetric deformation that cylindrical specimens experience during the shearing stages of a triaxial test....

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...

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

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...

Sonic NDE of Structural Concrete
Case histories are presented to illustrate applications of nondestructive evaluation (NDE) methods that use stress waves to characterize the conditions of concrete construction. The case...
