desasfaltado

Desasfaltado is a term referring to the process of removing asphalt or bitumen from a surface. This is often necessary in road construction, maintenance, and recycling. When roads reach the end of their lifespan, or when modifications are needed, the asphalt layer is typically removed. This removed material can then be processed and reused, a practice known as asphalt recycling.

The removal process itself can be achieved through various methods. Mechanical milling is a common technique where specialized machines with rotating drums cut away the asphalt surface. This process grinds the asphalt into smaller pieces, which can then be collected. In some cases, older asphalt may be heated to soften it before removal, making the process more efficient.

Desasfaltado is a crucial step in the lifecycle of asphalt pavements. It allows for the recovery of valuable materials, reducing the need for virgin aggregate and bitumen. This contributes to more sustainable construction practices by minimizing waste and conserving resources. The recycled asphalt can be incorporated into new asphalt mixes, thereby closing the loop in the material cycle. The quality and composition of the asphalt removed can influence the feasibility and methods used for its subsequent recycling.
