Anti-fatigue flexible road structure
An anti-fatigue flexible road structure comprising one or more subbase structure support layers located on a compacted soil foundation, in which at least one of the subbase structure support layers is an elastic subbase layer for more completely distributing surface loads, and the elastic subbase layer comprising aggregate, filler, binder, and recycled tire rubber, the content of the regenerated tire rubber is 3-5 percent by weight of the sum of the aggregate, the filler and the rubber. The elastic sub-base layer has a fatigue life that is at least 25% higher than that of the non-elastic sub-base layer that does not contain the reclaimed rubber, and in addition, the elastic sub-base layer has an elastic modulus that is at least 25% lower than that of the non-elastic sub-base layer that does not contain the reclaimed rubber.
抗疲劳柔性道路结构，包括位于压实土地基上的一个或多个底基层结构支撑层，在该底基层结构支撑层中，至少有一个是弹性底基层，用于更完全地分布表面负载，且该弹性底基层包括骨料、填料、粘合剂和再生轮胎橡胶，其再生轮胎橡胶的含量为骨料、填料和橡胶之和的3‑5重量百分比。弹性底基层的疲劳寿命比不含再生橡胶的非弹性底基层高出至少25％，此外，弹性底基层的弹性模量比不含再生橡胶的非弹性底基层低了至少25％。
