Pavement Boring, Sawcutting and Joint Intersection Details
Make sure the recess size and depth are maintained within the specified limits. All
surfaces of the recess must be clean and dry. If any of these surfaces is damp, it is
desirable that it be dried and blown clean with a compressed air blast. The recess
side walls must be perpendicular to the pavement surface. The bottom surface must
be flat or slightly concave to assure that the shallow base rest securely and in true
position. The recess can best be drilled using a diamond-faced core drill in a sturdy,
stable drill rig.
Mark on the pavement surface the aiming direction of the light by chalk, nails or
other devices.
