The application of waste materials and the uncertainty surrounding climate change are significant issues that highlight the need for creative reforms that will lead society toward a more sustainable future for all. The open dumping of Coal Bottom Ash (CBA) occupies a significant portion of valuable land and has a substantial consequence for the environment and humanity. To find a suitable method for handling CBA and enhancing our environments against excess contaminations, this study provides the application of CBA in Warm Mix Asphalt (WMA) and the bibliometric analysis of the study’s keywords. This article also reviews the contemporary technologies of previously published articles on WMA. Based on the previous publication on CBA by Scopus, China contributed 23.1% of the Scopus publications between 2016 and 2023, followed by Malaysia (15.4%) and Belgium (3.8%). This showed that China contributed the most in terms of the countries’ total contributions. Out of all the academic disciplines, materials science, engineering, physics, and astronomy have contributed 55.6%, 24.4%, and 20.0% to Scopus publications, respectively. Therefore, additional reviews are required to confirm CBA’s continued effectiveness in WMA.

摘要

The application of waste materials and the uncertainty surrounding climate change are significant issues that highlight the need for creative reforms that will lead society toward a more sustainable future for all. The open dumping of Coal Bottom Ash (CBA) occupies a significant portion of valuable land and has a substantial consequence for the environment and humanity. To find a suitable method for handling CBA and enhancing our environments against excess contaminations, this study provides the application of CBA in Warm Mix Asphalt (WMA) and the bibliometric analysis of the study’s keywords. This article also reviews the contemporary technologies of previously published articles on WMA. Based on the previous publication on CBA by Scopus, China contributed 23.1% of the Scopus publications between 2016 and 2023, followed by Malaysia (15.4%) and Belgium (3.8%). This showed that China contributed the most in terms of the countries’ total contributions. Out of all the academic disciplines, materials science, engineering, physics, and astronomy have contributed 55.6%, 24.4%, and 20.0% to Scopus publications, respectively. Therefore, additional reviews are required to confirm CBA’s continued effectiveness in WMA.
