Synthetic Aggregates and Bituminous Materials Based on Industrial Waste.

Area of Science:

• Materials Science
• Environmental Engineering
• Civil Engineering

Background:

• The circular economy necessitates innovative materials and production methods.
• Industrial wastes like stone dust and polymer waste pose environmental challenges.
• Sustainable alternatives are needed for conventional building materials.

Purpose of the Study:

• To create novel building materials from stone dust and polymer waste.
• To evaluate the suitability of these materials for the building materials engineering sector.
• To develop circular economy-compliant materials for road infrastructure.

Main Methods:

• Combining stone dust and polymer waste to form artificial aggregates.
• Assessing material properties using the Micro-Deval test.
• Developing bituminous mastic using stone dust and cooking oil.
• Evaluating new materials against standard product benchmarks.

Main Results:

• Artificial aggregates achieved a Micro-Deval coefficient of 7.7%, suitable for road construction.
• Stone dust demonstrated potential as a sorbent for dyes without leaching.
• A novel bituminous mastic composite was created using waste materials.

Conclusions:

• Developed materials align with circular economy principles.
• Potential applications include road construction aggregates and dye sorbents.
• Waste valorization offers sustainable solutions for the building industry.
