Abstract
A paving mixture for application to a surface and a method for the same are provided. 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, wherein the binding material layer comprises at least 13% of the bitumen in the paving mixture by weight, the aggregate material layer contains an asphalt mixture that provides a road surface, and the aggregate material layer and the binding material layer are combined on the surface within 30 seconds of application of the binding material layer.
Claims20
A paving mixture for a road surface, the mixture comprising:
- a bitumen binding material layer applied as a liquid and used to form a bitumen binding material layer of the road surface;
- and
- an aggregate material layer applied on top of the bitumen binding material layer,
- wherein the bitumen binding material layer comprises at least 13% of total bitumen in the paving mixture by weight,
- wherein the aggregate material layer comprises a mixture of aggregate and bitumen that provides a road surface and wherein the aggregate and bitumen are mixed prior to application to the bitumen binding material, and
- wherein the paving mixture is at least 2.5 inch thick after application.
A method of applying a paving mixture to a surface, the method comprising:
- applying a bitumen binding material as a liquid to the surface to form a bitumen binding material layer on the surface at a rate of 0.395 gallons/yd2;
- and
- applying an aggregate material layer on top of the binding material layer,
- wherein the aggregate material layer comprises a mixture of aggregate and bitumen that provides a road surface and wherein the aggregate and bitumen are mixed prior to application to the bitumen binding material, and
- wherein the bitumen binding material layer comprises at least 13% of total bitumen in the paving mixture by weight.
A method for applying a paving mixture to a surface, the method comprising:
- applying a bitumen binding material as a liquid to the surface to form a bitumen binding material layer on the surface;
- applying an aggregate material layer on top of the bitumen binding material layer;
- and
- compacting the bitumen binding material layer and the aggregate material layer together,
- wherein the bitumen binding material layer comprises at least 13% of total bitumen in the paving mixture by weight, and
- wherein the aggregate material layer comprises a mixture of aggregate and bitumen that provides a road surface and wherein the aggregate and bitumen are mixed prior to application to the bitumen binding material.
