Options for asphalt to new retaining wall?

[jpcjguy]

Hi all,

I have a post of a new retaining wall that replace a failing railroad tie wall here: https://www.garagejournal.com/forum/threads/retaining-wall-progress.548007/#post-11238234
This thread is more about options for fixing the asphalt that meets the wall. While the driveway overall is in ok shape, there are no funds to redo that now. So the thought is to use cold patch to fix where we cut for the wall. Contractor and I are thinking just some cold patch but wanted to make sure we are not missing any better options.

After building my house, I used cold patch for this and it worked out great. You might use a piece of plywood to protect the wall when you compact it. Cold patch will be soft for a few months to a year, but since you aren't going to be driving on this area, it shouldn't be a worry.

Crack filling products will take care of the thinner spaces. (The instructions for the cold patch will tell you how much space you need for it.)

yes to cold patch left out on a warm day in the sun and then compacted for the big area. Might even think of using wood or steel plate with a mini sledge to keep it controlled and not chip the block.
As said above i'd try foam backer rod and this if its as narrow as it looks. https://www.homedepot.com/p/Sika-29...4VzUYMqeTgPVDIJ6cLRoCyHYQAvD_BwE&gclsrc=aw.ds

Keep in mind that wall will heave and thaw differntly then the driveway so it might take a couple tries to get something you can live with.

I'd clean out the broken chunks of asphalt use sand topping mix, pour in the void dry and hit it with a water hose.

Dont use cold patch since it will only last about a year then it loses it's binding and becomes a bunch of small stones. I've used it to repair asphalt problems but it doesnt last very long. Use asphalt or just get some stone to pack in that gap.

Because your gap is narrow and between a rigid block wall and asphalt, I'd recommend self-leveling polyurethane sealant over cold patch. Cold patch is more ideal for potholes and broad surface repairs, not joints between dissimilar materials.

First put Backer rod in the space, then Self-Leveling Polyurethane Sealant

Thanks for the info - did not think about dissimilar materials. I was also looking at Aquaphalt - seems pricey though ($65 for 50lb vs $19 for the stuff in the bag) ....and since this is not being driven on or anything I was thinking of filling with stone (either 57 or some crusher run that I have) and then a top layer.

Couldn't a paver come in and patch what was necessary rather than a complete re-pave?

Call a couple asphalt companies for estimates and see how they'd do it. If you're not redoing the driveway they'd probably want to cut out a strip along the wall and add to the fill in that area so the edge of the driveway doesn't sink overtime. But even if they can just fill the gap for you that's there now and forget any extra work it would last longer then anything you could do yourself.

I’ve used this product from Lowe’s to patch potholes where the street meets my driveway. I was sure to clean out all the loose debris and dust and tamped it down really good. Honestly this product has held up better than hot asphalt patches the city did with their pothole crews right next to mine. It’s messy sticky stuff, but I’m impressed how well it has held up. As skinny as the area you’re doing, I bet a couple 50lb $15 bags would easily get the job done

That is the bag stuff that I mentioned vs. the Aquaphalt above - glad to hear it works well. Really this area will get no traffic (foot or vehicle) since it is next to the wall.....
