I just had my driveway asphalt coated. In general it looks pretty good, but there are 2 areas (about 10 sq ft each) where the (due to the location) the asphalt was laid by hand and not rolled on by a large machine - so the surface has some roughness and is not as flat as the rest of the driveway. (Aesthetically this is not a problem as one area is where trash cans will be situated, and the other is the creation of a side path through some bushes.)
Today it is raining and the first thing I noticed is that those manually laid areas are extremely porous - rain is running down to them and then just disappearing. I called my asphalt guy and he stated to me that "oh once the asphalt has cured then those areas will naturally seal up"
I am skeptical of the curing process closing up those porous areas, and my concern is that in the winter there is potential for cracking due to ice expansion.
Will the porous areas seal themselves up?
Are my concerns about cracking in those areas valid?
If seal coating is advised, is doing this myself a smart or dumb thing to do?
