System and method for forming shaped grooves in an airport runway

A method of grooving an airport runway with grooves that have a trapezoidal shaped profile, comprising the steps of:

• providing a rotating blade having a plurality of cutting teeth that move in a direction of rotation, each of said cutting teeth has a body with a face surface, a bottom surface and a wide section disposed behind said face surface and above said bottom surface, wherein said face surface and said bottom surface have a constant first width, and wherein said wide section has a wider second width, wherein said body expands from said face surface to said wide section along said direction of rotation;
• and
• cutting a plurality of grooves in a surface of an airport runway utilizing said rotating blade.

A method of grooving an airport runway, comprising the steps of:

• providing a rotating blade having a plurality of cutting teeth extending from a circular blank, wherein each of said cutting teeth has a face surface, a bottom surface and a wide section disposed behind said face surface and above said bottom surface, wherein said face surface and said bottom surface have a constant first width, and wherein said wide section has a second width that is wider than said first width, wherein each of said cutting teeth has angled surfaces that extends from said face surface and said bottom surface to said wide section;
• and
• cutting a plurality of grooves in a surface of an airport runway utilizing said rotating blade, wherein each of said grooves has a trapezoidal profile.
