Abstract:
A road surface cutting system, which is capable of cutting a hole into both cold asphalt and dry concrete surfaces for the deployment and securement of roadway marking devices, without the need for lubrication to be applied to said road surface being cut, said road surface cutting system comprising:a deflection housing for containing debris generated from said hole being cut into said road surface; said deflection housing having a top portion and a bottom portion where said bottom portion is proximate to said roadway surface when said deflection housing is deployed, wherein said bottom portion defines a cutting region on said road surface when said hole is being cut; said deflection housing being capable of substantially vertical movement towards said road surface when said deflection housing is being deployed proximate said road surface and capable of substantially vertical movement away from said road surface when said deflection housing is to be removed from said road surface; one or more road surface cutting blades operably positioned within said deflection housing and being powered to cut said holes into both cold asphalt and dry concrete surfaces; said one or more road surface cutting blades being capable of articulated movement within said deflection housing from a retracted non-cutting position, when said deflection housing is not being deployed proximate to said road surface, to a deployed cutting position extending beyond said bottom portion of said deflection housing, when said bottom of said deflection housing is proximate to said road surface and said one or more cutting road surface cutting blades are engaged in cutting said hole into said roadway; said deflection housing being operably connected to a vacuum system for evacuation of debris from an area proximate to said one or more road surface cutting blades, when said one or more road surface cutting blades are being deployed, and deposited into a debris collection container; and said vacuum system simultaneously generating a flow of air within said deflection housing so as to cool said one or more road surface cutting blades.
