Abstract
The present invention is directed to a rut resistant coating and a method for applying the rut resistant coating on an existing surface for increasing resistance to high vertical and horizontal strains and high shear stresses. The method includes applying a binding material layer of the rut resistant coating on the existing surface to provide a substantially impermeable moisture barrier to the existing surface, the binding material layer containing less than about 11% of the total binding material of the rut resistant coating. After applying the binding material layer, an aggregate mixture layer is applied on the binding material layer to provide the wear surface of the rut resistant coating and support and structure to the rut resistant coating to resist rutting, the aggregate mixture layer containing an asphalt solution.
