Round up or another systemic weed killer would be the best option.
The weeds that grow in block paving generally grow in the kiln dried sand that is used to brush in between the blocks, this sand helps to lock the pavers together tightly. That is why you should replace the kiln dried sand quickly if you jet wash your drive and wash out the original sand. It is rare for the weeds to come from below unless you have had the Cowboys in.
I should point out that I run my own landscape gardening business.

If you're going to use Roundup then get the one where you pump it up and then spray. The ones where you squeeze the trigger get quite tiring after a while.
