Can scarification depths greater than 1 inch be achieved?
A. Yes. However, each pavement must be evaluated individually to determine whether the asphalt properties contained in the pavement will allow a greater depth. Typically, most urban pavements do not require depths greater than one inch. Some highway pavements may be suited for depths of 1-1/2 to 2 inches, but a thorough pavement evaluation must be performed in conjunction with a cost analysis to determine the feasibility of achieving a 2 inch depth.
