FATIGUE-RESISTANT FLEXIBLE ROAD STRUCTURE
A fatigue-resistant flexible road structure that includes one or more sub-base structural support layers positioned over a compacted earth foundation. At least one of the sub-base structural support layers is an elastic sub-base layer for more completely distributing surface loads. The elastic sub-base layer includes aggregate, filler, binder, and recycled tire rubber. The recycled tire rubber is included in an amount of 3% to 5% by weight of the sum of aggregate, filler, and rubber. The elastic sub-base layer has a fatigue life at least 25 percent greater than a non-elastic sub-base layer without recycled rubber. Further, the elastic sub-base layer has a modulus of elasticity at least 25 percent lower than a non-elastic sub-base layer without recycled rubber.
