Mine Voids: What's Down There, Anyway? Characterizing Mine Voids for Civil Construction

Density Tests above Zero Air Voids Line
(Originally published in J. of Geotechnical Engineering, 1989, 115(7), 1003-1018.)...

Sand Structure Differences Resulting from Specimen Preparation Procedures

Intergranular Void Ratio - Steady State Strength Relations for Silty Sands

Mitigation of Void Development under Bridge Approach Slabs Using Rubber Tire Chips
The problem of void development under bridge approach slabs has been correlated to the use of integral abutment bridges (Schaefer and Koch, 1992). This void development then causes settlement...

Determination of Void Fabric Tensor of Soils Without Radial Sampling Bias

Initial Fabric and Uniformity of a Sand Specimen - An Image Analysis Approach

Design and Construction Considerations in Filling A Void Under the Webber Dam Spillway

Breaking Wave Measurement by a Void Fraction Technique
Breaking of steep surface gravity waves in seas under moderate to strong wind forcing always involves the entrainment of air into the water column below the air-sea interface. As such,...

Application of the Phase Change Process to One-Dimensinal Consolidation Behavior of Peat
In this study, based on the fact that the pore of fibrous peat consists of the macro (outer) pore between organic matters and the micro (inner) pore inside organic matter, an approximate...

Alabama DOT Implementation of Hot Mix Asphalt QC/QA Procedures

A Revised Methodology to Minimize Bias in Determining the Porosity and Void Tensor of Particulate Media
Increased recognition of the importance of fabric in the observed response of particulate media under monotonic and cyclic loading has led to the development of new procedures to quantify...

Densification of Asphalt Pavements by Traffic
Since asphalt pavements rut when the voids are filled with asphalt (and voids can become filled by traffic densification) the voids that develop under traffic are vital to any mix design...

Infrared Thermographic Sensing of Sewer Pipeline Problems
When a sewer caves in, it often takes the street, sidewalks, and surrounding buildings along for the ride. These collapses endanger public health and safety. Repairing a sewer before such...

Realistic Specifications for Manufactured Sand
Data which demonstrate the beneficial effect of using fine aggregate having high fines contents on concrete properties are presented. All data indicate that the use of a high fines content...

Estimation of Chemical Grout Void Filling by Electrical Resistivity

Concrete for Sealing Voids in Rubble Structures
Permeability of rubble-mound breakwaters and jetties to sand transport and wave transmission results in increased costs for dredging and navigation. Guidance is provided for economically...

Evaluation of Concrete Bridges by Impact-Echo
Strength of post-tensioned bridge structural members primarily depends on the tensile capacity of their post-tensioning steel reinforcement. To prevent corrosion, the post-tensioning steel...

Mathematical Characterization of Fabric and Its Use in Mechanics of Geomaterials
Increased evidence of the influence of their discrete nature on the observed behavior of geomaterials has prompted a number of investigators to look at these materials at the microstructural...

Frequency Spectrum Analysis of Ultrasonic Testing Signal in Concrete
Description is given on high-speed sample apparatus connected with the CTS-25 low frequency ultrasonoscope and computer, the time domain of ultrasonic testing signal is transformed to...
