Abstract

A method of resurfacing exposed surfaces of existing roads, and a resurfaced road. The method may include forming stress absorbing membrane interlayers (SAMIs) over the exposed surface of the existing road. The SAMIs may include a first layer of a binding material and a fiber material. The method may also include disposing an asphalt mixture directly over the SAMIs. The disposed asphalt mixture may cover the SAMIs. Additionally, the method may include shaping the asphalt mixture disposed over the SAMIs.

Claims (36)

1. A method of resurfacing an exposed surface of an existing road using a machine, the method comprising:

positioning the machine over the exposed surface of the existing road, the machine comprising:

a fiber material storage for storing fiber material;

a first group of sprayers and a second group of sprayers for spraying distinct layers of binding material over the existing road;

a fiber material distribution component for disposing the fiber material; and

a channel positioned adjacent to the second group of sprayers for supplying an asphalt mixture;

forming stress absorbing membrane interlayers (SAMIs) over the exposed surface of the existing road, wherein forming the SAMIs includes:

spraying a first layer of the binding material over the existing road using the first group of sprayers;

distributing the fiber material on the first layer of the binding material with the fiber material distribution component; and

spraying a second layer of the binding material on the fiber material and the first layer of the binding material; and

forming an asphalt mixture over the SAMIs after the forming of the SAMIs.

2. The method of claim 1 , wherein the asphalt mixture is bonded directly to the SAMIs.

3. The method of claim 1 , wherein the fiber material distribution component is located between the first group of sprayers and the second group of sprayers.

4. The method of claim 1 , wherein the fiber material is distributed directly on the first layer of the binding material shortly after the spraying of the first layer of binding material, and wherein the second layer of the binding material is sprayed directly on the fiber material shortly after distributing the fiber material.

5. The method of claim 1 , wherein the exposed surface includes surface defects.

6. The method of claim 1 , wherein the asphalt mixture is formed over the SAMIs shortly after the forming of the SAMIs without any intervening contact with the SAMIs.

7. The method of claim 1 , wherein the machine further comprises a cutting device, and

wherein the method further comprises cutting the material to a predetermined length prior to distributing the fiber material.

8. The method of claim 1 , wherein the asphalt mixture comprises:

aggregate; and

at least one of: asphalt cement or asphalt emulsion.

9. The method of claim 1 , wherein distributing the fiber material on the first layer of the binding material comprises embedding the fiber material into the first layer of the binding material while the first layer of binding material remains in liquid form.

10. The method of claim 1 , wherein forming the asphalt mixture over the SAMIs comprises embedding the asphalt mixture into the second layer of the binding material while the second layer of the binding material remains in liquid form.

11. The method of claim 1 , wherein shaping the asphalt mixture disposed over the second layer of the liquid binding material comprises pressing the asphalt mixture into the second layer of the liquid binding material.

12. The method of claim 1 , wherein forming the SAMIs comprises running the machine over the exposed surface of the existing road to progressively resurface the existing road.

13. The method of claim 1 , wherein forming of the SAMIs and forming of the asphalt mixture are performed sequentially in less than approximately one minute to approximately two minutes.

14. The method of claim 1 , wherein the machine further comprises a screed positioned adjacent to the channel, and

wherein the method comprises shaping the asphalt mixture with the screed directly after forming the asphalt mixture over the SAMIs to form a resurfaced road.

15. The method of claim 14 , wherein the resurfaced road can be driven on by a vehicle shortly after the shaping of the asphalt mixture.

16. The method of claim 1 , wherein the binding material comprises polymer modified asphalt emulsion.

17. The method of claim 16 , wherein the binding material includes:

elastic characteristics; and

impermeable characteristics.

18. The method of claim 1 , wherein spraying the first layer of binding material comprises bonding the first layer of the binding material to the exposed surface of the existing road.

19. The method of claim 18 , wherein spraying the first layer of the binding material comprises sealing the exposed surface of the existing road.

20. The method of claim 13 , wherein the machine is operated at a speed of at least 20 feet per minute in sequentially forming the SAMIs and the asphalt mixture.
