Abstract
A paving mixture for application to a surface and a method for the same. The mixture comprises a binding material layer applied to the surface to form a base layer on the surface, and an aggregate material layer applied on top of the binding material layer. The binding material layer can be applied in an amount of at most 0.125 gallons/yd2. The aggregate material layer contains an asphalt mixture that provides a road surface. The aggregate material layer and the binding material layer can be combined on the surface within 30 seconds of application of the binding material layer. Additionally, multiple paving mixtures may be applied to the surface.
Claims20
A road surface, the mixture comprising:
- a binding material layer forming a base layer of the road surface, the binding material in the binding material layer having a residue of at least 80%;
- and
- an aggregate material layer applied on top of the binding material layer,
- wherein the binding material layer comprises an amount of at most 0.050 gallons/yd2 on the surface,
- wherein the aggregate material layer comprises a mixture of aggregate and bitumen that provides a road surface.
A method for applying a paving mixture to a surface, the method comprising:
- applying a binding material layer to the surface to form a base layer on the surface, the binding material in the binding material layer having a residue of at least 80%;
- applying an aggregate material layer on top of the binding material layer;
- and
- compacting the binding material layer and the aggregate material layer together,
- wherein the binding material layer is applied in an amount of at most 0.050 gallons/yd2 on the surface, and
- wherein the aggregate material layer comprises a mixture of aggregate, pulverulent material, and bitumen that provides a road surface and wherein the aggregate, pulverulent material and bitumen are mixed prior to application to the binding material.
A method of applying a paving mixture to a surface, the method comprising:
- applying a binding material layer to the surface to form a base layer on the surface at a rate of at most 0.050 gallons/yd2, wherein the binding material in the binding material layer having a residue of at least 80%;
- and
- applying an aggregate material layer on top of the material layer,
- wherein the aggregate material layer comprises a mixture of aggregate, pulverulent material, and bitumen that provides a road surface and wherein the aggregate, pulverulent material and bitumen are mixed prior to application to the binding material.
