Wear-Resistant Steels for Processing Demolition Asphalt

Excavated asphalt refers to the asphalt material that accumulates during the dismantling or rehabilitation of roads—usually by milling or breaking up with an excavator. After mechanical processing, this material can be reused in road construction. The prerequisite is high-performance machines capable of handling highly abrasive material. Wear-resistant steels, such as those offered by UnionStahl, are in particularly high demand.

Recycling Demolition Asphalt: Efficient Material Cycle with High-Performance Wear Steels

Demolition asphalt is generated during the dismantling or rehabilitation of roads—for example, through milling or breaking up with an excavator. After proper processing, the material can be reused in road construction. This requires robust machines that can withstand highly abrasive conditions. High-quality wear steels, like those supplied by UnionStahl, are essential for this process.

Recycling Plants Under Continuous Load

Whether for removal, crushing, or sorting, crushers, screens, and conveyor systems are exposed to significant stress during the recycling of demolition asphalt. To minimize downtime and reduce maintenance costs, plant operators rely on wear steels from UnionStahl. These steels extend the service life of critical components such as linings, baffle plates, and conveyor troughs—ensuring reliable and cost-effective operation.

Heat-Resistant Recycling: The Challenge of Thermal Treatment

In thermal asphalt processing plants, the material is heated to temperatures of up to 160 °C—and in certain processes, even up to 450 °C. Such extreme conditions require materials that are not only abrasion-resistant but also heat-resistant. This is where Creusabro^® excels: this special steel combines hardness, temperature resistance, and self-hardening properties, making it ideal for demanding recycling applications in the asphalt sector.

Creusabro®: An Efficient Solution for Abrasive and Thermal Loads

Thanks to its unique properties, Creusabro® significantly extends the service life of highly stressed components such as blades, wear plates, and baffle plates. This makes it the first choice for processing broken asphalt—and a key factor in achieving an efficient and sustainable recycling process.
