Claim 13:
14. The depth guide of claim 11 further comprising
a depth control gauge, said depth control gauge being elongate and having an adjustable length and a proximate end and a distal end, said depth control gauge being interposed between the distal end of the extension arm and the proximate end of the depth indicator, with the proximate end of the depth control gauge being attached to the distal end of the extension arm and with a proximate end of the depth indicator being attached to the distal end of the depth control gauge, and with the depth control gauge being oriented substantially vertically,
with said depth control gauge having associated therewith a first length and a second length, with said second length being longer than the first length, and a means for adjusting the length of the depth control gauge to the first length or to the second length or to a plurality of intermediate lengths, each intermediate length longer than the first length and shorter than the second length,
with said depth control gauge further having a means for fixing the length of the depth control gauge at the length to which it is adjusted;
whereby the length of the depth control gauge is adjusted to set the position of the distal end of the depth indicator a desired height above the roadbed.
