Rheological Properties of Rubber Modified Asphalt Binder in the UAE
In the 21st century, United Arab Emirates (UAE) is one of many countries that started focusing on building a sustainable eco-friendly system based on recycling waste materials rather than depositing them into landfills. Rubber generated from tires waste is one of those materials that have been proven to be a beneficial material in several applications especially in pavement engineering. This study aims at investigating the rheological properties and performance of Crumb Rubber-modified (CRM) asphalt binders that contain different crumb rubber contents by weight of the binder (5%, 10%, 15%, 20%, and 25%). The testing plan includes conventional tests, namely: penetration, softening point, and Rotational Viscosity (RV) tests and Superpave tests using Dynamic Shear Rheometer (DSR). Moreover, the AASHTOWare Pavement ME Design software was utilized to simulate the effect of using CRM asphalt binders on the pavement performance under local climatic conditions using two different pavement structures (thick and thin). Results showed that increasing the Crumb Rubber (CR) content increased the softening point, RV and rutting parameter (G*/Sinδ) significantly indicating an increased resistance to permanent deformation. The simulated pavement performance showed that modifying the binder with the CR in the thick and thin pavement structures has enhanced the pavement service life remarkably. The control asphalt binder failed due to rutting for thick and thin pavement structures at 12 years and 13 years, respectively. The modified asphalt binder with 25% CR content enhanced the pavement service life by up to 65% and 53% for thick and thin pavement structures, respectively.
