| dc.description.abstract | The processing of rubber tire waste poses significant health and environmental risks, while potholes pose safety risks to commuters and patches often provide a temporary and unreliable solution to roadway maintenance. The incorporation of rubber tire waste into pothole patches offers a sustainable solution to both problems. The use of rubber tire waste in asphalt pothole patches has shown improvement in structural properties. Improved structural properties include resistance to rutting, fatigue, thermal cracking, and high temperature failure. The main components of asphalt mixtures are aggregates and binder materials. Asphalt mixes have displayed success with modification of rubber for virgin components, such as aggregates and binder. Reliable Tire Recycling is a Manitoba company which converts rubber tire waste materials into value added products. This project explores the incorporation of crumb rubber obtained from Reliable Tire Recycling into an asphalt binder. Four (4) asphalt binder samples were prepared with high-speed shear mixing which included a virgin binder sample as a control and samples with varying quantities of crumb rubber and warm mix additives. Quality of rubber was confirmed to meet technical specifications for moisture content, fiber and metal content, and crumb rubber size prior to mixing. Following mixing, each sample was subjected to verification tests to quantify success. The tests displayed results for the rheological and mechanical properties of the binders. The properties indicate the binders’ performance at high temperatures, resistance to common modes of failure, and workability. The results displayed that an increase in rubber led to an increase in the viscoelastic properties. This indicates an improved resistance to rutting and fatigue failure. However, incorporation of warm mix additives increased viscosity more than double the binder mix at the same rubber quantity. This indicates poor workability of the mix with incorporations of warm mix additives. Further research on rubber use in asphalt binders for pothole patching is recommended. Additional testing should be conducted on rubber-modified binder samples to analyze cold temperature performance and the effects of long-term aging. It is recommended to mix and test more formulas with varying quantities of crumb rubber to optimize the results. | |
