Unlike parking lots and driveways, highways are constantly re-compacted by continuous traffic. Highways are also not subect to the continuous attack of petoleum derivatives in the same areas.
Slurry seals, chip seals and micro seals all have their proper applications, but parking lots and driveways, in my humble opinion, are not the place for these applications. On parking lots and driveways use only coal tar or asphalt emulsion seal coats.
