Garden centres will sell you a stand-up version of the torch for that purpose. $25-$40, uses the same tanks. Of course the carbon footprint's hellacious. The weeds are telling you there aren't enough of the real footprints in those places. Something to think about over winter. If the traffic pattern won't change, then you need a better seal—like papa suggests below—or take up the unneeded paver and replace it with a non-mowing ground cover that'll pretty much choke out the weeds; anything from clover to daylillies (which will grow thru blacktop) that need no care and make it easy to spot the weeds when they're readily pullable, but hide the few, wee ugly sprouts unlike your pavers.I have a patio with bricks and the black fabric barrier, now years later it slows the weeds but some are popping up. What I do is use a propane plumbers torch to burn the weeds out. Do it when they are small and sprouting and it will only take a few minutes. If you have grass growing between stones now, go out and torch them out and you will be ahead next season. It will be easy now as many have dried out and will burn fast. If the grass and weeds are wet, it is even easier to torch because the moisture will boil and kill the plant with steam when it is hit with the flame.
I think there are a couple of issues with black top (asphalt?). Firstly, rainwater will not drain into the ground but run into the city sewers. Secondly, how does one remove the black top should a future occassion arise that makes removal desirable?Black top will do a better job
From my experience if you wish to put patio block or pavers down you should use a compacted gravel, pea gravel and sand base for driveways. For lighter use such as walkways and patios ( patios not having a hot tube placed on them ) you need to dig down deep enough to include a one inch compacted lake sand base. This will help to keep the blocks from shifting all over.I think there are a couple of issues with black top (asphalt?).

I called Quest Plastics earlier this morning. They make a black fabric that carries an infinite guarantee. The lady said place the black fabric on top of the soil, then place the patio stones on top and fill the joints between the stones with sand.
Oh please... I purchased the Giant Weed Torch (http://www.leevalley.com/en/garden/page.aspx?p=47306&cat=2,2300,44822) from Lee Valley 8 years ago and am still using the same propane tank that I started with and it was only about half-full then. Can't be that 'hellacious' a carbon footprint.Garden centres will sell you a stand-up version of the torch for that purpose. $25-$40, uses the same tanks. Of course the carbon footprint's hellacious.

Definitely a better price than Lee Valley.... mind you when I bought mine it was about $38 because it was new and no one wanted them at the time. Only thing I wouldn't like with this one is the shorter hose. Lee Valley's comes with 10' and often that's too short (have to keep moving the tank) so I would recommend getting the 15' hose with Ceiling Cat's alternative.
