Abstract: Abstract This article studies the enhancement of bitumen properties by the addition of crumb rubber obtained from different scrap tyres. Crumb rubber extracted from scrap tyres through shedding and other traditional process has smaller size, which has the ability to enrich the various relevant characteristics of bitumen. An extensive study of different scrap tyres obtained from different automobiles (heavy, medium, and light) was conducted and also analysed its effects on bitumen properties. Different dosages of the crumb rubber added to bitumen evaluate its physical properties, Marshall stability, and indirect tensile strength to identify the optimum dosage. And retained Marshall stability test is used to assess the resistance against moisture susceptibility. The result obtained proved that modified crumb rubber bitumen is more effective and can be utilized for wide applications such as road constructions. A comparative analysis is executed between the CRMB samplings and bituminous mixes utilizing waste tyres of different automobiles and recommended the best automobile waste tyre for the purpose of bitumen modification and to acquire best outcomes.
