Reflective cracks are cracks in a new asphalt overlay or surface course that reflect the crack pattern in the pavement structure underneath in the old road. They are caused by vertical or horizontal movement in the pavement beneath the overlay. There are several methods that have been used in attempts to eliminate or minimize reflective cracking. This paper discusses a method -- the asphalt crack relief layer -- used recently on a contract construction project on Interstate 40 near Grants, New Mexico. The material, placed between the old pavement and the new overlay, consisted of three and a half inches of open graded hot mix which was produced from 100% crushed limestone aggregate and a viscosity graded bituminous material.
