Your asphalt will be the most susceptible to damage for the first 6-12 months after it is installed. Most issues are merely cosmetic in nature (slight surface scuffing from wheels turning sharply or minor indentations from sharp objects), and will fade over the next few weeks as the asphalt continues to cure.
Avoid spilling any corrosive liquids on the asphalt (such as gasoline, transmission fluid, anti freeze or oil), as they will cause damage to the surface.
If the finished edges of your asphalt are higher than the surrounding lawn, we recommend that you backfill (build up the sides with black dirt) and then seed it. Without the proper lateral support, the asphalt edge is more prone to cracking, particularly if a vehicle drives over the edge of the asphalt. Please be sure to backfill.
