Atomistic Modeling of Interactions Between Minerals and Organics in Civil Infrastructure Materials (2020-03-26)This document comprises a sum of research efforts aimed at the discovery of mechanisms of interaction between mineral (inorganic), and organic substances used or occurring in civil infrastructure materials. This endeavor ...

(2022-07-04)Asphalt binder is an intrinsically heterogenous material that consists of various chemical groups and structures. Asphalt heterogeneity is further exasperated in modified asphalt binders, which incorporate chemical and/or ...
-
(Texas A&M University, 2006-04-12)The focus of this dissertation is on constant displacment rate experiments on asphalt concrete and on developing continuum models in a general thermo-mechanical setting which will corroborate with the experimental results. ...
-
(1986)Limitations of current testing procedures for asphalt concrete, asphalt additives, and alternative binders have made necessary a more theoretical basis for testing procedures. A new parameter, Marshall Toughness, is ...
-
(Texas A&M University, 2004-09-30)Pavements are a major part of the infrastructure in the United States. Moisture damage of these pavements is a significant problem. To predict and prevent this kind of moisture damage a great deal of research has been ...
-
(1997)The purpose of this research was to determine what effects composition, temperature, rubber content, and aging time have on the low temperature properties of various asphalts. These properties, failure stress, failure ...
-
(Texas A&M University, 2008-10-10)Polymers are added to asphalt binders primarily to stiffen the binder at higher temperatures and thus to protect the pavement against rutting at summertime temperatures early in the pavement's life. Also, it has been ...
-
(2022-07-17)As the cost of virgin asphalt materials continues to rise, transportation agencies are moving towards using higher amounts of recycled asphalt pavement (RAP) in the construction of asphalt mixtures. The use of RAP provides ...
