Utilization of Recycled Polypropylene as an Additive in Making Asphalt Polymer Using the Extracting Process

Introduction

The increasing amount of plastic waste is a serious problem in various countries, and finding effective solutions to manage this issue is crucial. One potential solution is to use plastic waste as additives in various materials, including asphalt. This study explores the potential use of recycled polypropylene as additives in making asphalt polymers by extrusion methods. The use of recycled polypropylene in asphalt can not only reduce the volume of waste but also create building materials that are stronger and more environmentally friendly.

Background

Asphalt is a widely used material in road construction due to its durability and resistance to wear and tear. However, the use of traditional asphalt can have negative environmental impacts, such as contributing to greenhouse gas emissions and pollution. The incorporation of recycled polypropylene into asphalt can help mitigate these issues while also improving the material's properties. Polypropylene is a type of plastic that is commonly used in packaging and other applications, and its recycling can help reduce the amount of waste in landfills.

Methodology

This study was conducted using variations in asphalt comparison, recycled polypropylene, and sand aggregate. The asphalt mixture, polypropylene, aggregate, dicred peroxide, and maleate anhydride were heated at 160 ° C and then processed using the extrusion method. The results showed that the asphalt ratio: polypropylene: aggregate (70: 30: 30: 300) produces asphalt polymers with optimal compressive strength of 2.73 MPa and water absorption is only 0.24%. The thermal analysis using DTA shows that the polymer asphalt decomposition temperature reaches 454 ° C, indicating a good thermal stability.

Results

The results of this study indicate that the use of recycled polypropylene as an additive in making asphalt polymers through the extrusion process has good potential. The origin of recycled polypropylene can increase compressive strength and reduce water absorption in asphalt. The FTIR spectroscopy shows that crosslinking occurs through radical reactions initiated by peroxide dikumil, involving hydroxyl groups in asphalt with polypropylene and maleate anhydride. The morphological analysis using SEM shows structural changes in the asphalt mixture, indicating that recycled polypropylene is well integrated into the asphalt structure, thereby increasing the strength and asphalt resistance.

Discussion

The use of recycled polypropylene in asphalt can have several benefits, including reducing the volume of waste, improving the material's properties, and creating building materials that are stronger and more environmentally friendly. The results of this study indicate that the use of recycled polypropylene as an additive in making asphalt polymers through the extrusion process has good potential. However, further research is needed to test the resistance of asphalt polymers in real conditions and conduct further analysis of the impact of the use of polypropylene recycling on the performance of asphalt in the long run.

Conclusion

In conclusion, this study demonstrates the potential use of recycled polypropylene as additives in making asphalt polymers by extrusion methods. The results show that the use of recycled polypropylene can increase compressive strength and reduce water absorption in asphalt. The incorporation of recycled polypropylene into asphalt can help mitigate the negative environmental impacts of traditional asphalt while also improving the material's properties. Further research is needed to fully explore the potential of using recycled polypropylene in asphalt and to develop more sustainable and environmentally friendly building materials.
