Latest Patents

Leung is associated with 1 patent, titled “Fatigue-Resistant Flexible Road Structure.” The invention describes a road structure built over a compacted earth foundation and supported by one or more sub-base layers. At least one layer uses an elastic mixture of aggregate, filler, binder, and recycled tire rubber.

The patent specifies recycled tire rubber at 3% to 5% by weight of the combined aggregate, filler, and rubber. Compared with a non-elastic sub-base without recycled rubber, the elastic layer is described as having a fatigue life at least 25% greater and a modulus of elasticity at least 25% lower. These properties are intended to help distribute surface loads and improve resistance to fatigue.
