“…There are two kinds of steel slag, namely basic oxygen furnace (BOF) and electric arc furnace (EAF) [120]. The type of steel slag is determined by the cooling down process and chemical composition of the slag [74,121,122]. In 2006, an estimated 114-280 million tons steel slag was produced globally [123].…”

A Review of the Utilisation of Recycled Waste Material as an Alternative Modifier in Asphalt Mixtures

The possibility of using waste materials in road construction is of great interest as their utilisation may contribute to reducing the problems of hazard and pollution and conserve natural resources. Thus, there is an urgent need to find a sustainable method for using waste materials as a substitute in the standard asphalt binders. There are several concerns about the physical and chemical properties and mechanical performance of asphalt pavements incorporated with waste material in the effort to reduce permanent deformation of the road surface. This review article presents a brief discussion of the asphalt mixtures modified with waste material, and the recycled materials used as a modifier in the asphalt mixture. The present paper summarises the use of crumb rubber, crushed concrete, steel slag, glass fibre and plastic waste in asphalt mixtures. The use of waste materials as a modifier in asphalt mixture resulted in improved asphalt pavement performance. Results advocate that rubberised asphalt mixture with desired properties can be designed as an additive with a friendly environmental approach in construction materials. The researches that adopted the influence of usage, recycle waste material to improve the performance of the asphalt of the road are still limited compared to other construction fields.

“…Recycling materials have been reported to be utilized in different composition in different layers of road structure from the top surfacing layer to the underneath layers [8]. The processing cost, the engineering properties, the evidence that demonstrate the viability of the material and its positive impact on the long-term performance of the road construction works are what characterizes and favours the use of that specific recycled waste material [8].…”

Research objective: analysis of waste disposal issues in the mining and mineral processing industry of the Russian Federation. Research methodology: economic and environmental challenges concerned with mining and mineral processing waste in dumps and tailings were analysed. Results: an option is proposed to dispose of the waste rock generated by the mining and processing industry by using it for construction of railways and motor roads. This technology makes it possible to avoid construction of quarries and temporary settlements for their development along the road route, which will decrease the environmental impact and significantly reduce the time and cost of road construction. Conclusions: The proposed technology helps to achieve a significant economic effect (no costs for transporting materials from remote areas of the country), reduce the adverse environmental impact of mining operations and, in the long term, prevent dump formation.

“…Based on a survey, the waste disposal cost caused a negative impact on the construction company economics [4]. For some contractors, construction waste disposal has become more expensive due to the cheaper local landfills are increasingly scarce or even close to their capacity [5]. Therefore, the implementation of a waste management program in the site considered to be an essential component of the construction process [6].…”

Construction activities (construction and demolition) is one of the major contributors in the generation of waste generation in landfills. Recycling waste of demolition construction is considered effective, but for the case in Indonesia not many know the benefits of the utilization due to lack of socialization of the impact of construction waste and not many people who know the economic value in waste recycling products construction. The aim of this study is to analyze the potential of use construction waste recycling products in terms of economy and its development in Indonesia, case study in Jakarta area. This paper will use descriptive analysis with literature studies based on several references related to similar cases. The result show that 40-60% of waste from construction and construction can be recovered and recycled. Economically, waste minimization is also feasible because reuse of construction waste is estimated to be worth 2-3% of the total project budget. Therefore, the construction industry can save by applying waste minimization in the project.
