  2. Studying the Effects of Thermo-oxidative Aging on the Mechanical, Tribological and Chemical Properties of Styrene-butadiene Rubber

    Mhatre, Vihang HridaynathVirginia Tech2022

    … degradation and eventual tire failure is 'rubber aging.' It can be defined as an alteration in the mechanical, chemical, physical, or morphological properties of elastomers under the influence of various environmental factors during processing, storing and use. Some of these environmental factors …

  4. A study of Asphalt Aging Behavior Using Molecular Dynamics Simulations

    Pan, Jielin

    Oxidative aging is a major issue in asphalt pavements that leads to hardening of the asphalt, which further contributes significantly to asphalt pavement embrittlement and eventually results in excessive pavement cracking. In addition, the performance of asphalt binder is also highly related to its …

  5. Non-destructive quantitative assessment of oxidation in aged and rejuvenated asphalt concrete pavements using a non-collinear wave mixing approach

    McGovern, Megan EUniversity of Illinois at Urbana-Champaign2016

    Oxidative aging in asphalt concrete pavements is one of the chief contributors to pavement degradation. Oxidation contributes to the formation of a diffuse micro-flaw population in the mastic. This damage is primarily concentrated at the top (surface) of the pavement, where exposure to oxygen is …

  7. Mechanical properties of degraded PMR-15 resin

    Tsuji, Luis C. (Luis Christophe), 1974-Massachusetts Institute of Technology1999

    Thermo-oxidative aging produces a non-uniform degradation state in PMR-15 resin. A surface layer, usually attributed to oxidative degradation, forms. This surface layer has different properties from the inner material. A set of material tests was designed to separate the properties of the oxidized …
