 It's like painting your house. You want to paint the siding and seal that siding up on your house before your siding's rotten and you have to replace it. Same thing with our surface seal treatments on the roadways. Get them sealed up, take care of them. I got to think that pothole filling is like whack-a-mole around here. Right. Temporary fix, yeah. So how do you determine which roads need to be repaired first?
