Old Tyres Bounce Back in Spanish Slab Track

Headquartered in Madrid, Acciona S.A. has found an innovative way to use old automobile tires in slab track. After two years researching reuse of waste, Acciona developed the track for Granada Light Metro (MLG). The system's basic objective is providing a damper layer between the concrete slab and the rail, which offers sufficient elasticity to contain vibrations from passing LRVs, thus reducing line impact to surrounding buildings, as well as providing secure rail fixing. The MLG system supports one of the hallmarks of light rail, that its running surface can be used by other transportation modes. The material combines recycled automobile tires and resin with a polymer matrix. The solution is then poured into a lateral groove between the concrete slab and rail. Acciona claims this reuses about 15 tires per linear meter of straight track and dampens vibrations from passing LRVs.
