Another picture, this is on a slight slope, so most of the hot tar ended up at the end...but that left us with a LARGE crack still at the top.

That looks like a mess, can you drive over it without getting it all over the place. Minister & I tried fixing the parking lot, looked lot like your place. Got some asphalt stuff in bags(kind of like concrete mix comes in. That didn't work well. Used tar & sand in smaller ones, little better. Then he mixed up in a small mixer a batch of cement & used a trowel & covered over the top with sand & tar. That lasted the longest but eventually several yrs later some of concrete pieces had worked their way up after breaking & we had some small holes plenty big enough for ladies heel to get caught in. Would like better solution! Also for filling in hole where asphalt seem to have gotten soft. Hope you get a good answer!

The Portland cement concrete will not be successful for patching. No patching method will yield the results of all-new paving.
The black liquid asphalt-based material can be used along with clean dry sand as a filler. I know of no better crack patching method.

Cut the section out and re patch like the city dies

Really appreciate you sharing! I wasn’t aware of this product. Seems very reasonably priced also. I’m going to try it! Thank you!!
