Moisture Susceptibility Of Asphalt Mixes Using Phosphonylated Recycled Polyethylene, David Herndon
All Dissertations
ABSTRACT
Today's asphaltic concrete pavements are expected to perform better even though they are experiencing increased volume of traffic and increased loads over what has been experienced in the past. Research has indicated that the addition of polymers to asphalt binders can enhance many properties of the asphalt pavements to help meet these increased demands.
There remains a serious problem that the addition of polymers to asphalt binders generally does not address. This involves the interfacial cohesiveness of the bond between the aggregate and the binder. Some aggregates are highly hydrophilic (water-loving) while asphalt binders and most polymers tend to …
Characterizing Liquefaction Resistance Of Aged Sand Deposits, Hossein Hayati
Characterizing Liquefaction Resistance Of Aged Sand Deposits, Hossein Hayati
All Dissertations
Presented in this dissertation are the results of various studies conducted to characterize the liquefaction resistance of aged natural deposits. The data considered include laboratory and field test results from sites in five countries with particular focus on multiple locations in the South Carolina Coastal Plain.
A new liquefaction potential map of the peninsula of Charleston, South Carolina, is presented. Liquefaction potential is expressed in terms of the liquefaction potential index (LPI) developed by Iwasaki et al. and calculated using 44 cone penetration test (CPT) profiles. The CPT profiles are supplemented with information from the 1:24,000 scale geologic map by …

Development Of A Methodology For Evaluating And Anticipating Improvised Explosive Device Threat Activity Using A Fault Tree Based Process, Benjamin Bennett
All Dissertations
This document is a redacted version of the original dissertation titled 'Development of a Methodology for Evaluating and Anticipating Improvised Explosive Device Threat Activity Using a Fault Tree Based Process.' To allow for publication, information was removed which was considered sensitive in nature or which could be used by those who employ the Improvised Explosive Device, to negate any advantage gained by this research. The complete un-redacted dissertation is available (with proper vetting) to those whishing to further develop the concepts outlined in this document. Those interested in obtaining access to the complete document should contact the Joint IED Defeat …
