In 2003 and 2006, California used 224,700 waste tires behind two freeway walls; the lighter fill reduced pressure on the structures by about 30%

California has taken a progressive step by integrating millions of waste tires into its freeway construction. This innovative approach involves the use of tire-derived aggregate in retaining walls, which effectively minimizes structural pressure. Not only does this practice present numerous advantages in civil engineering, but it also helps conserve natural resources while tackling the tire disposal dilemma.
