“…The stability of an asphalt mix refers to the maximum load needed to cause failure of the specimen when a constant rate of 50 mm/min is applied. The results of this test are presented in Table (7). Based on these results, the asphalt mix achieves a maximum stability of 965 kg at a bitumen content of 5%.…”

The incorporation of crumb rubber derived from waste tires into asphalt mixtures is an effective strategy for improving the fatigue resistance of asphalt pavement. This research focused on hot mix asphalt (HMA) mixtures that replaced 40% of natural aggregate (limestone) with recycled concrete aggregates (RCA) treated with waste engine oil (WEO). Two types of asphalt binders were used: traditional AC60-70 and the same binder modified with 3%, 4%, and 5% crumb rubber (CR) by the weight of bitumen. The study aimed to investigate the influence of CR polymers on asphalt pavement performance and explore the feasibility of using WEO for asphalt modification. Various asphalt mixtures with different CR percentages were tested to evaluate their mechanical properties, including stability, fatigue resistance, permanent deformation, and loss of stability. The durability and resistance of the asphalt mixtures were also assessed through indirect tensile strength testing before and after exposure to water. The study found that the CR-modified mixes showcased several advantages compared to conventional mixes. These included enhanced fatigue and permanent deformation properties, reduced susceptibility to temperature variations, and improved resistance to moisture damage. Overall, the CR-modified mixes demonstrated improved performance compared to the regular mixes. The results indicated that the developed HMA, which included 40% RCA and 4% crumb rubber binder, improved stability and the Percentage of Indirect Tensile Strength Ratio (ITSR). Among the different CR percentages tested, the 4% crumb rubber modification demonstrated the highest fatigue life. Furthermore, the addition of 3% waste engine oil to the modified control mix (MCM) with 40% RCA and 4% CR appeared to enhance the durability of the asphalt mixture. Ultimately, the utilization of MCM with 40% RCA, 4% CR, and 3% WEO was found to enhance the performance of the asphalt pavement mixtures that were developed.

“…Rubber and elastomer materials have been widely used for a long time as asphalt cement's modifiers and have received considerable attention from asphalt scientists due to their suitable properties, which have the ability to enhance various aspects of the asphalt cements and mixtures [17][18][19][20]. Furthermore, as a result of the environmental demand to reuse waste products, the utilization of rubber materials in asphalt mixtures offers alternative or more engineering application than recovered scrap tires.…”
