The amount of unwanted waste produced in recent decades has quickly increased due to rapid population growth, technological advancements, and the widespread use of state-of-the-art products and services in the industry. Different researchers have carried out extensive studies on waste materials. Regretfully, most investigations focus only on the performance of HMA concrete that has been modified using one or two types of waste. Therefore, this study investigates an extensive review of the qualities and utilization of four types of wastes, viz., Coal Bottom Ash (CBA), Waste Cooking Oil (WCO), Waste Engine Oil (WEO), and Rice Husk Ash (RHA), as well as assessing their bibliometric analyses. The wastes that were being investigated showed a notable improvement in Warm Mix Asphalt (WMA) concrete. The WMA technology has successfully reduced the environmental issues of high production and compaction temperatures. The previous publications on CBA, WCO, WEO, and RHA identified 3,914 published documents between 2009 and 2023. Only 32 of these documents were published by Scopus. The academic disciplines of engineering, materials science, environmental sciences, and others have contributed 37%, 29%, 19%, and 15%, respectively, to Scopus publication. The United Kingdom made a significant contribution of 50% to Scopus publication compared to other countries. Furthermore, the findings also revealed that 89.4% (29 documents) were technical articles and only 10.6% (3 documents) were review articles. Further review of the rheological and microscopic properties of the four wastes is needed.
