But here’s something that might be different for your crew to help you get quality results. Bring a tape measure in addition to your measuring wheel when estimating the project so you can assess the width and depth of cracks. Use the cracks’ measurements to decide not only what method you’ll use to fix them (I’m talking cleaning & filling versus routing & filling versus saw-cut & patch), but also what material you’ll use to fix them.

So, if you have a transverse crack that’s more than ¾ of an inch wide and deeper than 1 inch, you may elect to use a hot pour mastic to fill it.
