Durability and Aging Characteristics of Sustainable Paving Mixture
Researchers incorporated shredded low-density polyethylene plastic waste into asphalt paving mixtures, testing the durability and aging characteristics of the resulting material. Reusing waste plastic in road construction is one approach to reducing the plastic that otherwise enters the environment and breaks down into microplastics.
The Utilizing of Recycled Plastic Waste as an Alternative for Zero Cement Paving Blocks
This study tested the compressive strength and water absorption of paving blocks made entirely from recycled plastic waste without cement. Using plastic waste in construction materials offers a way to permanently remove plastic from the environment while meeting the growing need for durable urban infrastructure.
Eco-Friendly Pavement Innovation: Compressive Strength of Plastic–Sand Paver Blocks
Researchers developed eco-friendly paving blocks using post-consumer PET, HDPE, and LDPE plastic waste combined with local sand in coastal Indonesia, finding that a 1:1 plastic-to-sand ratio achieved the highest compressive strength of 9.84 MPa, meeting Class D criteria suitable for garden paths and light pedestrian use.
Utilization of Plastic Waste in Interlocking Paver Blocks for Sustainable Pavement Construction
Researchers found a way to turn plastic waste into strong concrete blocks for roads and walkways by mixing shredded plastic pieces with regular concrete ingredients. The plastic-concrete blocks were just as strong as normal concrete blocks, offering a promising solution to reduce the mountains of plastic waste that pollute our environment. This approach could help tackle two major problems at once: getting rid of plastic trash that can break down into harmful microplastics, and reducing the need to mine natural materials for construction.
