re-coring deck and ballast work

Normally if you butt joint you grind out a shallow vee nearly to the
depth of the original material and extending about 4 inches back from
each side of the joint. You then laminate in progressive widths of
cloth until you fill the vee. You have then effectively turned the but
joint into a continuation of the original material.
I'd call that a scarf joint. No butts about it...
