Variation of internal structure and performance of polyethylene- and polypropylene-modified bitumen during blending process

Luca Desidery et al.

Summary: The study found that the type and form of polyolefin have a significant impact on the mechanical response time of the composite material during the blending process of polyethylene, polypropylene, and bitumen. Polyethylene shows higher affinity with bitumen and produces modified bitumen with acceptable performance after blending for 210 minutes.

Repurposing waste plastics into cleaner asphalt pavement materials: A critical literature review

Shenghua Wu et al.

Summary: The current practice of recycling waste plastics into cleaner asphalt pavement materials involves 7 major types of plastics. Determining the optimum dosage of waste plastics is crucial for improving the performance parameters of asphalt mixes. Additional research is needed to fully understand the effects of various plastics on the performance of the pavement and potential environmental and economic impacts.
