“…Table 1 presents the results of J nr , % recovery, and traffic levels determined according to AASHTO MP19-10. It can be seen that the J nr differences of all binders containing CRM exceed the maximum allowable value of 75%, which is consistent with the findings by Wills et al [36]. This phenomenon was mainly due to the binders' extremely low J nr values at 0.1 kPa.…”

“…As expected, both rubberized binders prepared by terminal blend and continuous blend showed higher softening point, apparent viscosity, and lower penetration value compared to control (bitumen 80/100 penetration). This confirmed previous studies that incorporating rubber crumb to base bitumen results in higher viscosity and elasticity [6,11,22]. It is important to note that the rubberized binder produced by the terminal blend (TB) showed higher softening point and apparent viscosity followed by a continuous blend binder (CB) and control.…”

“…The development of an effective interaction between bitumen and rubber is mainly an experimental iterative process. Previous studies determined that the properties of rubberized binders are highly governed by the selection of rubber crumb parameters (rubber types, rubber size, and rubber contents) and blending parameters (blending temperature, blending duration, and blending rate) [5,6]. Modification of these parameters will affect the rubberized binder properties and imposes on the performance of the rubberized asphalt mixtures.…”

This study aims at comparing the permanent deformation of Stone Mastic Asphalt (SMA) rubberized asphalt mixtures produced by the wet process. In this study, rubberized binders were prepared using two different blending methods, namely, continuous blend and terminal blend. To study the creep behaviour of control and rubberized asphalt mixtures, the dynamic creep test was performed using Universal Materials Testing Apparatus (UMATTA) at different temperatures and stress levels. Zhou three-stage creep model was utilized to evaluate the deformation characteristics of the mixtures. In all test conditions, the highest resistance to permanent deformation is showed by the rubberized mixtures produced with continuous blend binders. This study also reveals that the permanent deformation of rubberized mixtures cannot be predicted based on the characteristics of the rubberized binders.

“…The use of crumb rubber in asphalt pavements has shown promising results in previous studies (Shafabakhsh et al 2014;Moreno et al 2013;Hossain et al 2016;Ghavibazoo, Abdelrahman 2014). Considering facts, that crumb rubber modified bitumen performance mainly depends on processing conditions, there are still open questions related with modifying temperature, interaction time, crumb rubber type and amount (Lo Presti et al 2012;Jeong et al 2010;Willis et al 2013;Wang et al 2013).…”

Abstract. Rubber derived from grinding of recycled cars and trucks tyres may be successfully used as a bitumen modifier. Number of researches reported sufficient characteristics of rubber modified asphalt binders or modified asphalt mixes in terms of improved permanent deformation and fatigue cracking. The behavior of crumb rubber asphalt binders depends on several factors, such as modification method, rubber content and size, modification temperature, mixing speed and time applied during the digestion process. The aim of this study is to evaluate the effect of crumb rubber amount and type on modified bitumen low and high temperature properties. This paper presents results of unmodified bitumen, crumb rubber crumb rubber and polymer modified bitumen. Low and high temperature properties have been evaluated using bending beam rheometer and dynamic shear rheometer. Moreover, softening point and viscosity tests have been performed. The study results revealed that crumb rubber modified bitumen performed better than pure bitumen and similarly to polymer modified bitumen.
