Construction & Civil Use

Scrap tires often carry potential far beyond their original function. When properly processed, they can be transformed into valuable materials for civil engineering and construction projects. Shredded tires, often referred to as tire-derived aggregate (TDA), are increasingly used as lightweight fill for retaining walls, embankments, and roadbeds. This material improves drainage and resists settlement, making it an effective solution for engineers managing soft or unstable soils during large-scale projects.

Tire-derived aggregate has proven especially valuable in slope stabilization and erosion control. Its flexibility and resilience allow it to absorb ground movement and vibration that might otherwise crack or displace traditional materials such as stone or compacted soil. When placed beneath roadways, TDA minimizes frost heave in colder climates and reduces long-term maintenance demands. These properties extend the functional life of infrastructure while diverting significant volumes of waste from landfills.

In industrial settings, scrap tires are increasingly used as an alternative fuel source that burns cleaner than coal in cement kilns and paper mills. This practice, known as tire-derived fuel (TDF), helps lower emissions and decreases reliance on nonrenewable fossil fuels. It also provides a consistent energy source for manufacturing processes requiring high heat.

Municipalities and contractors are adopting ground rubber from recycled tires into asphalt mixtures. Rubberized asphalt creates quieter road surfaces and enhances durability, particularly in regions with heavy traffic or temperature extremes. These applications demonstrate innovative ways to extend the lifecycle of scrap tires. Many state departments of transportation have reported improved performance and extended service life with these modified pavements, reducing the frequency of costly repairs.

Before using tire-derived products, engineers and project managers should consult local guidelines and environmental standards. Many states provide detailed specifications to ensure safety and effectiveness. With thoughtful application, recycled tires can contribute meaningfully to resilient and sustainable development across a variety of industries.
