Abstract

This application relates to a method of forming multiple inlaid patterns to complete a final predetermined rotational pattern onto or into a pavement surface. The pattern may be selected for functional or decorative purposes. In one embodiment the method includes the steps of providing a first template created of multiple blocks with portions of rotational isometric patterns having a predetermined pattern; impressing the first template into the pavement surface when the pavement surface is in a pliable state forming an impression therein; removing the first template from the pavement surface exposing the impression; providing a grid having a predetermined pattern matching the pattern of the first template; inserting the grid into the impression; and fixing the grid in position within the impression to form the inlaid pattern thereby creating multiple blocks of said portions of said patterns such that rotational isometric patterns form a final rotational predetermined isometric patterned preform.

Claims

1. A method of forming multiple inlaid patterns to complete a final predetermined rotational pattern onto or into a pavement surface comprising:

(a) a template for creating multiple blocks with portions of rotational isometric patterns;

(b) impressing said template into said pavement surface when said surface is in a pliable state to form an impression therein;

(c) removing said template from said surface to expose said impression;

(d) providing an inlaid rotatable preform grid that at least partially matches the pattern of said template;

(e) inserting said rotatable preform grid into said impression caused by said template;

(f) fixing said rotatable preform grid in position within said impression to form said inlaid pattern;

thereby;

(g) creating multiple blocks of said portions of said patterns such that rotational isometric patterns form a final rotational predetermined isometric patterned preform, wherein said final rotational predetermined isomeric patterned preform is formed using patterned orthant coding descriptors describing quadrants designated as (Q#), individual pattern square locations designated as (L#), and rotational pattern positions designated as (R*), where # represents the corresponding location or quadrant number and * represents the corresponding letter associated with each angular rotational positional expressed in degrees from a vertical y-axis.

2. The method of forming an inlaid pattern of claim 1, wherein after the preceding step (f), fixing said grid in position within impressions for forming said inlaid patterns is accomplished by passing a portable heater over the surface of said grid.

3. The method of claim 1, wherein said pavement surface is asphalt.

4. The method of claim 3, further comprising the step of heating said asphalt surface prior to impressing said template into the asphalt surface.

5. The method of claim 1, wherein the step of fixing said grid in position within said impression comprises heating said grid after insertion of said grid into said impression to cause said grid to bond to said pavement surface.

6. The method of claim 5, wherein said grid is heated to a temperature within the range of approximately 100 to 400 degrees Fahrenheit.

7. The method of claim 5, wherein said grid is heated to a temperature within the range of approximately 150 to 350 degrees Fahrenheit.

8. The method of claim 1, wherein said grid comprises a pre-formed thermoplastic pattern.

9. The method of claim 1, wherein said grid is of unitary construction.

10. The method of claim 1, wherein said grid has a color contrasting with the color of said pavement surface.

11. The method of claim 1, wherein said grid comprises retroflective elements including glass heads and skid resistant elements that provide said template retroflective capabilities after said template is fixed in position within said impression.

12. The method of claim 11, wherein said grid is luminescent.

13. The method of claim 11, wherein said grid is fluorescent.

14. The method of claim 1, wherein said grid comprises an upper surface, wherein said upper surface is substantially flush with the surface of said pavement surface when said grid is fixed in position.

15. The method of claim 1, wherein said grid comprises an upper surface, wherein said upper surface is recessed below the surface of the pavement when said grid is in a fixed position.

16. The method of claim 15, wherein said grid comprises an upper surface, wherein said upper surface projects above the surface of said pavement when said grid is in a fixed position.

17. The method of claim 1, wherein said grid is a preform with a plurality of frame elements prior to inserting said grid into said impression, and wherein the preform frame elements have a width less than 12 inches.

18. The method of claim 17, wherein said frame elements have a width between ¼

inch and 4 inches.

19. The method of claim 1, wherein said predetermined pattern is decorative.

20. The method of claim 1, wherein said predetermined pattern is non-linear.

21. The method of claim 6, wherein said heating comprises passing a portable surface heater over a upper surface of said grid after said grid has been inserted into said impression.

22. An article of manufacture comprising;

a grid and/or a template for creating multiple blocks of portions of rotational isometric patterned preforms wherein said grid and/or template provides a final rotational predetermined isometric patterned preform based on properly positioning said multiple blocks wherein said positioning of said final rotational predetermined isometric patterned preform is formed using patternted orthant coding descriptors describing quadrants designated as (Q#), individual patterned square locations designated as (L#), and rotational patterned positions designated as (R*), where # represents the corresponding location or quadrant number and * represents the corresponding letter associated with each angular rotational position expressed in degrees from a vertical v-axis.

23. The article of claim 22, wherein said grid and/or template is a rotationally patterned thermoplastic perform.

24. The article of claim 22, wherein said grid and/or template is formed from a plastic material.

25. The article of claim 22, wherein said grid and/or template is formed from a thermoplastic material.

26. The article of claim 22, wherein said grid and/or template is formed from rubber.

27. The method article of claim 22, wherein said template is a preform with a plurality of frame elements prior to inserting said grid into said impression, and wherein the preform frame elements have a width less than 12 inches.

28. The article of claim 27, wherein said frame elements have a width between ¼

inch and 4 inches.

29. The article of claim 27, wherein said frame elements have a width between ⅜

inch and 2 inches.

30. The article of claim 27, wherein the thickness of said grid is between 80 and 100 mil.

31. The article of claim 27, wherein the thickness of said template is between 125 and 200 mil.

32. The article of claim 22, wherein said grid comprises a unitary grid of frame elements.

33. The article of claim 22 further comprising the step of pre-heating the asphalt surface after forming the impression.

34. The article of claim 22 further comprising the step of pre-heating the asphalt surface by using a portable heater prior to the impressing step.
