Narrow asphalt driveway cracks
(1/8th to ½ inch thick) are fairly common and can usually be addressed with
a rubberized emulsified crack filler. Ideally, thin asphalt driveway cracks
should be repaired as soon as they are discovered, and certainly before
winter, to prevent water from seeping into them and causing more damage.
When the water freezes it can cause the asphalt to lift and effectively
enlarge the crack.
Eventually the asphalt driveway
crack could begin to crumble the surrounding asphalt area, which is a much
more expensive asphalt driveway repair.

vacuum to remove dirt and other loose debris from the crack.
Finally, use a water hose to wash
out the crack of loosened debris, and let it thoroughly dry before applying
the crack filler.

depth of the crack. If it is more than a ¼ inch deep, fill the crack with sand

the asphalt driveway crack either using a caulking gun, or by pouring it into
