My question has to do with properly treating wide cracks in asphalt. I have an upcoming job where the cracks are 3/4″ and an inch deep. I know that filing the entire void with rubberized crack filler is not the correct solution. What I am looking for is a product or “trick” to assist in properly filling the majority of the void prior to treating the crack. Is using sand or filler rope recommended?
Also, I was also asked to treat cracks on a tennis court. The customer requested hot pour rubberized crack-filler. I’m a little hesitant because I worry the product will come up and track all over the surface under high heat and aggressive foot traffic. any suggestions.
Use a crushed aggregate material (crusher reject, large aggregate sand, squeegee material that has jagged edges, crushed slag, etc). Place the material in the crack about 1/2 inch from the top and then crack seal. Do not use silica sand of 8 mesh sand as it will roll out or migrate down and the sealer material will rupture.
