Most of these<br>additives are sustainable materials since it is derived from old scrap materials. All the<br>above-mentioned materials (W-LDPE, CR and SBS) were added with percentages of (2, 4,<br>and 6 percentage) of the weight of pure asphalt binder. Several tests were conducted to<br>evaluated the properties of improved asphalt binder such as penetration test, Ductility test,<br>Softening point test, Rotational viscosity test as well as thin-film oven test. The results of<br>investigation revealed that, the using of different types of PMB significantly improved the<br>physical properties and performance of asphalt. The using of sustainable waste materials<br>such as W-LDPE and CR significantly improve the properties of PMB and contribute in<br>recycling great amount of waste materials. Also, the results showed that the using of high<br>percentage of SBS (6%) significantly increase the viscosity of asphalt binder and that can<br>affect workability of Hot Mix Asphalt (HMA) compared with same percentages of WLDPE<br>and CR).<br>Keywords: Asphalt binder (Bitumen), Sustainable materials, Crumb rubbers, Physical<br>properties, SBS, Waste low density polyethylene<\/li>\n<\/ul>\n\n\n\n<div data-wp-interactive=\"core\/file\" class=\"wp-block-file\"><object data-wp-bind--hidden=\"!state.hasPdfPreview\" hidden class=\"wp-block-file__embed\" data=\"https:\/\/repository.qu.edu.iq\/wp-content\/uploads\/sites\/31\/2024\/09\/laboratory_evaluation_of_properties_of_modified_asphalt_binder_with.pdf\" type=\"application\/pdf\" style=\"width:100%;height:600px\" aria-label=\"\u062a\u0636\u0645\u064a\u0646 laboratory_evaluation_of_properties_of_modified_asphalt_binder_with.\"><\/object><a id=\"wp-block-file--media-fc4d0f5b-3e16-40e4-b82f-26c9b92b1972\" href=\"https:\/\/repository.qu.edu.iq\/wp-content\/uploads\/sites\/31\/2024\/09\/laboratory_evaluation_of_properties_of_modified_asphalt_binder_with.pdf\">laboratory_evaluation_of_properties_of_modified_asphalt_binder_with<\/a><a href=\"https:\/\/repository.qu.edu.iq\/wp-content\/uploads\/sites\/31\/2024\/09\/laboratory_evaluation_of_properties_of_modified_asphalt_binder_with.pdf\" class=\"wp-block-file__button wp-element-button\" download aria-describedby=\"wp-block-file--media-fc4d0f5b-3e16-40e4-b82f-26c9b92b1972\">\u062a\u0646\u0632\u064a\u0644<\/a><\/div>\n","protected":false},"excerpt":{"rendered":"<p>Laboratory evaluation of properties of modified asphalt binderwith different types of additivesEsraa R.
