The sandwich system is a cutting-edge technology that has revolutionized the world of athletics tracks. It represents a significant advancement in track construction, offering a range of benefits that enhance performance, durability, and safety for athletes. 1. Layered Construction: The sandwich system is so named because it consists of multiple layers stacked on top of one another, similar to a sandwich. These layers are carefully engineered to provide a combination of qualities that optimize the track’s performance. 2. Base Layer: At the very bottom of the sandwich system lies the base layer. This layer is typically made of asphalt or concrete and serves as the foundational support for the entire track. It provides stability and ensures that the track surface remains level and well-drained.
