Microstructural Analysis and Rheological Modeling of Asphalt Mixtures Containing Recycled Asphalt Materials
The use of recycled materials in pavement construction has seen, over the years, a significant increase closely associated with substantial economic and environmental benefits. During the past decades, many transportation agencies have evaluated the effect of adding Reclaimed Asphalt Pavement (RAP), and, more recently, Recycled Asphalt Shingles (RAS) on the performance of asphalt pavement, whil...
متن کاملEnvironmental Impacts of Producing Asphalt Mixtures with Varying Degrees of Recycled Asphalt Materials
The environmental impacts of producing asphalt mixtures with different percentages of asphalt binder replacement (ABR) are assessed using the technique of life cycle assessment (LCA). In this paper, only the material production phase of the pavement life cycle is considered. To improve the quality of the LCA, a regionalized life cycle inventory (LCI) database for the Northern Illinois region is...
متن کاملMicrostructural Simulation of Asphalt Materials: Modeling and Experimental Studies
Asphalt concrete is a heterogeneous material composed of aggregates, binder cement, and air voids, and may be described as a cemented particulate system. The load carrying behavior of such a material is strongly related to the local load transfer between aggregate particles, and this is taken as the microstructural response. Simulation of this material behavior was accomplished using a finite e...
متن کاملA Study on the Rheological Properties of Recycled Rubber-Modified Asphalt Mixtures
Using waste rubber in asphalt mixes has become a common practice in road construction. This paper presents the results of a study on the rheological characteristics of rubber-modified asphalt (RMA) concrete under static and dynamic loading conditions. A number of static and dynamic creep tests were conducted on RMA mix specimens with different rubber sizes and contents, and a series of resonant...
متن کاملCharacterization of Hot Bituminous-Asphalt Mixtures with Recycled Polyurethane Foam
Received: June 06, 2017 Revised: July 05, 2017 Accepted: July 19, 2017 Abstract: Introduction: The use of polymer wastes in pavement as road is an increasing trend in the road construction sector. Those new pavements reduce the amount of solid waste disposed into landfills and provide more sustainable construction due to the use of in-situ materials. Polyurethane foam waste is a thermostable po...
