Quantifying Workability, Compactability, And Cohesion Gain Of Asphalt Emulsion Cold In-Place Recycling, Sadie Casillas

Graduate Theses and Dissertations

To maximize the life and quality of a pavement, proper maintenance and rehabilitation are essential. Strategies for pavement rehabilitation with many sustainable benefits are pavement recycling. This dissertation focuses on two types of in-situ pavement recycling: Cold in-place recycling (CIR) stabilized with asphalt emulsion and full depth reclamation (FDR) stabilized with asphalt emulsion or foamed asphalt. One white paper (Chapter 2), two accepted peer reviewed journal articles (Chapters 3 and 4), and one submitted peer reviewed journal article (Chapter 5) are presented in this document to create better understanding of the unique material characterization of asphalt emulsion cold recycled materials, …

Best Practices For Asphalt Emulsion Particle Size Analyses Using A Coulter Counter, Logan P. Kiihnl

Graduate Theses and Dissertations

As asphalt pavements develop distresses, pavement preservation, maintenance, and rehabilitation treatments are used to mitigate distresses and extend the life of the pavement. Many of these treatments utilize asphalt emulsion. Previous research has linked particle size to material properties including viscosity and storage stability. General statements have also been made about particle size influencing emulsion performance while other researchers have identified a trend between particle size and prime coat penetration. Even though literature discusses the importance of particle size, there is little guidance on the best practices of asphalt emulsion particle size analyses, specifically with a Coulter counter.

Laboratory Comparison Of Full Depth Reclamation Stabilization Techniques Using Arkansas Field Materials, Chase Aaron Henrichs

Graduate Theses and Dissertations

Full depth reclamation (FDR) is a flexible pavement recycling technique that has not been explored in the state of Arkansas. FDR is unique in that it incorporates the entire flexible pavement section as well as a predetermined portion of the underlying base and sub-base materials with a stabilizer to create a new, stronger stabilized base course. Common stabilization techniques include the addition of asphalt emulsion, asphalt foam, or cement. Using the North Carolina emulsion FDR mix design, the Wirtgen foam FDR mix design, and the Portland Cement Association cement FDR mix design, field materials from four Arkansas highways in the …
