Answer: 
After reading the answers to my question I used it to repair a large crack in one of the garage floor slabs caused by settling. I cleaned the crack with a brush followed by vacuuming then filling it a little at at time adding more as the material settled into the crack but before it cured. It worked great and I actually used less than I thought I would based on prior comment by others.

Answer: 
Hello and thank you for your question. Asphalt has oils which release over time. These oils are bond breakers for polyurethane sealants. Sika does not recommend applying on asphalt for that reason.

Sikaflex it is a great product. I don't see why not work with blacktop! But remember blacktop it is more flexible/softer than concrete, so it could work or it could NOT work as longer as with concrete do!!!!

Rated 4.6 out of 5 by 25 reviewers.
Rated 5.0 out of 5.0 by Product went on really easily. Seems to be very durable. Time will tell as to how well it will hold up against the brutal summer sun and heat of the south. It's fairly runny, so you should definitely use backer rod if you have a fairly big hole to fill. October 25, 2016
Rated 5.0 out of 5.0 by Not cheap, but the best! Follow directions. This is a professional product. Easy to use and apply. It is for horizontal cracks only, don't expect it to work on slopes or verticals. Start slow and go over as you need. Adheres great and lasts. This is not typical caulk! October 2, 2016
Rated 5.0 out of 5.0 by Concrete Pool Project Great product to fill cracks in pool deck. Power wash first, wear gloves when filling cracks. Let set for a week or more then power wash deck before painting concrete. August 8, 2016
Rated 5.0 out of 5.0 by Great Product Preparation of the crack was the hard part. This sealant is somewhat self leveling. A putty knife is required. You will want to check it as it sets up as it does flow into the crack and you may need to add more sealant and smooth with the putty knife again. It was slower curing than I expected. This was done in my son's house in Phoenix, AZ where it is dry, so I expected it to cure faster. Not drying so fast may be good if it is a long crack as it gives you time to work with it smooth it out. The crack had variations in width to be fair to the product. I had very satisfactory results. Home Depot sells a pair of Gorilla gloves, that worked well in protecting my hands and survived to protect another day. I cleaned the putty knife with a wet paper towel. Cut the very tip of the tube as it will give you more control of the sealant. May 31, 2016
Rated 4.0 out of 5.0 by fixed my crack I had a big nasty crack in my concrete driveway, I used this product to fill the gap. The directions say to just put it down on the crack with a caulking gun and let it sit. It is self leveling. After the fact I kind wish I would have used a putty knife on it to level it out. It kind has a little pump where the crack was. Look at my pictures and you can see what I am talking about. It seems durable though, and I don't expect it to fall off or anything. All I did for prep was sweep the cracked part of the driveway with a broom. September 25, 2013
Rated 5.0 out of 5.0 by Great product Great product! Not sure what to say about it.... it works. Easy to apply using a caulk gun, and it sealed my concrete perfectly. Used it on both the interior and exterior of my basement to prevent leaks. Had it there several months now and haven't seen any leaking. Now I am just trying to fill the minimum required characters because I have nothing more to say about it. December 4, 2015
Rated 3.0 out of 5.0 by OK but tedious with caulk gun This product performs as advertised. My only complaint is using a caulk gun can make this job slower than it should be job. I used it for expansion joints and it was difficult to do a professional looking job because of the nature of using a caulk gun (unless you use one regularly). I went though 2 tubes of this product before I stumbled across another brand that comes in a 32 oz plastic container. You squeeze it out like wood glue. I simply found the 32 oz container much easier and quicker. It also leveled out quicker than what came in the caulk tube. You may be perfectly fine with using a caulk gun, but I preferred the plastic container with the resealable cap.. It was also much cheaper. March 30, 2014
Rated 4.0 out of 5.0 by Sika seals shallow sidewalk splits Sikaflex flexible sealant is a cinch to use, and provides a nice, durable repair to those smaller cracks that develop in your sidewalk or driveway. I also like that the sealant, once cured, remains flexible, allowing for continued seal, even with seasonal movement of the concrete. A word of caution, however-- Sikaflex does work on cracks up to 1" wide, but only up to 1/2" deep-- a very small window of usability, in my opinion. If the cracks being repaired are deeper than 1/2", then you'll have to find a different product.. For SMALL sidewalk and driveway repairs, I'd recommend this product. August 6, 2013
