The Use of Waste Polymers in Asphalt Mixtures: Bibliometric Analysis and Systematic Review

Abstract

Asphalt is widely employed in road construction due to its durability and ability to withstand heavy traffic. However, the disposal of waste polymers has emerged as a significant environmental concern. Recently, researchers have used polymer waste to modify asphalt pavements as a new approach. This approach aims to improve pavement performance and address the environmental concerns of polymer waste. Researchers have demonstrated that incorporating polymeric waste into asphalt mixtures can lead to performance improvements in asphalt pavements, particularly in mitigating common distresses including permanent deformation and thermal and fatigue cracking. The current comprehensive review aims to summarize the recent knowledge on the usage of waste polymers in asphalt mixtures, encompassing their impact on performance properties and mixture design. The review also addresses different types of waste polymers, their potential benefits, challenges, and future research directions. By analyzing various studies, this review offers insights into the feasibility, effectiveness, and limitations of incorporating waste polymers into asphalt mixtures. Ultimately, this contributes to the advancement of sustainable and environmentally friendly road construction practices.

National Pavement Design Method (MeDiNa) applied to rehabilitation and restoration: a literature review

“…Literature review techniques, such as systematic literature reviews and bibliometric analyses, have proven to be of great value for evaluating a given topic, being applied in a multidisciplinary approach across various fields of science and technology (Caiado et al, 2017;Liz et al, 2023;Sarti Junior;Baptista;Biotto, 2024;Alves et al, 2024;Cavalcante et al, 2024). Specifically, literature reviews have contributed to investigations of applications related to paving (Abejón, 2021;Jwaida et al, 2023;Pinheiro et al, 2023).…”

The Use of Waste Ceramic in Concrete: A Review

“…The estimated annual production of these materials is 400 million metric tons that can be reused in concrete production. Alternatively, waste materials are sent to a landfill, where a landfill site is designed to contain these non-degradable substances, which cause environmental issues and soil contamination [8][9][10][11][12]. However, since the production of waste is directly linked to economic activity and population growth, it is an underlying part of both developing and developed societies, even though in most cases it represents an inefficient use of resources.…”
