Thanks
I need to get on this too.
Have the same issues you do.

My SIL is in the business of fixing commercial parking lots. He spent about $35K on a hot rubber crack filler machine and says nothing else is any good.
I have listed two I have tried that are significantly better than the crack filler you pour from a gallon container.

Would this be appropriate for an asphalt roof as well?
We're on our second home with a large asphalt driveway, and I too have tried just about product available off the shelf locally. I've tried thick liquid products, trowel grade products and calk.
Every one of them has been hit/miss. Cracks are typically going to move (why the crack is there in the first place), thus cracking the product you'er attempting to fill it with.
As Donald said above, something flexible and rubberized will hold up best. That's been my experience anyway.

Hello !
Consumer products will hard be equal to industrial ones, but even industrial products don't always work well. I would try PMA (polymer modified asphalt) and in particular an asphalt modified with DuPont Elvaloy or with some SBS. Preferable grades are PG 58-34 or 64-34 or at least 58-28 or 64-28 which should flow easier and fill in the cracks better. I believe you don't need products of higher hot temperature grades normally used in road industry for cracks (mastic). Viscosity with PMB is always high, so, naturally, it should be hot (150-160C) during use. PMA with Elvaloy is better.

Make a friend in the local highway administration or transportation authority and see if they can get you a bag or two of cold patch.
