“…This may be due to the diffusion of those short polymer chains in the LDPE to the bitumen molecules to stimulate the healing of the material. Previous studies (Ahmedzade et al, 2013;Farahani et al, 2017) show that the LDPE modified bitumen undergoes no J o u r n a l P r e -p r o o f observable changes in functional groups relative to the control bitumen, which confirms that this kind of modification of the control bitumen with LDPE is overwhelmed by physical process. The short chains of the LDPE melted in the unaged bitumen tends to aggregate and form a kind of network structure within a continuous polymer phase, which will potentially increase the healing performance of the unaged bitumen.…”

“…It has been reported that recycling LDPE and modifying asphalt increases bitumen's high-temperature performance and decreases its temperature susceptibility. Additionally, LDPE is highly resistant to corrosion and offers good waterproofing [28]. The following are the fundamental properties of LDPE, according to [11,12].…”

“…If plastic is added with additional material, the resultant PMB viscosity tends to be above the 3 Pa.s limit, whereas if the plastic has been chemically modified, the resultant viscosity is usually below the 3 Pa.s limit. The combination of plastic and crumb rubber or SBS produces a PMB with a significant increase in the viscosity parameter, up to the point that 50% did not comply with the 3 Pa.s limit(Al-Abdul Farahani et al, 2017b;Yan et al, 2015;Yang and Cheng, 2016;Zhang and Hu, 2016). This significant increment in viscosity is generated by the internal interactions of the components, the high quantity of modifiers added to the bitumen, and the structural reinforcement created by the polymers(Al-Abdul .…”
