Had a patch filled in with Tarmac, quite a decent size ..the Tarmac etc has been placed andpressed however where the old Tarmac meets thea new Tarmac there has been nothing placed.

Whenever I saw the council filling in potholes they put this black sealant around tahe new Tarmac where it met the old Tarmac.

Shouldn't there be something placed like a sealer or something ?

Am I going to have to call the guy back ?

No. Will be fine if work was carried out properly.

I asked a contractor on a site I was working about this, apparently there is a method known as side sealing which can be employed in certain conditions, where rather than a line of bitumen on the top there is something used on the joining faces where the two sections meet.

Could it be its been used in this case too?

Side sealing- effectively heated bitumen poured in to fill voids, add adhesion between the two, and provide a seam of layer works are required.
If it's done correctly without- ie cut to a neat edge, compacted etc, it should be fine

Sounds a bit like they hoyed a bit of del set into the hole tamped it in and ran but I haven't seen it.
The overbanding with hot poured bitumen you talk about on "proper roads" is no longer considered best practice, as it can be a cause of skidding when wet, mainly motorbikes. The preferred method now is to only coat the cut vertical face.
