  "Sealing An Old Jacksonville Profile" – Week of February 25, 2008

  By now, if you've been listening to this podcast for any length of time, you've heard me talking about seal coat. That's a summertime surface application where we put down sticky asphalt and cover it with rock in the hopes of sealing water out of a road's base. But in the winter, seal coat isn't practical because the asphalt can contract in cold temperatures and let loose the rocks it was supposed to be sticking down. Instead, we perform what's called fog seal. Fog seal is a similar process to seal coat except for the fact that no rock is spread on top. Weather permitting, TxDOT's special jobs crew is scheduled to fog seal FM 2493 or Old Jacksonville Highway south of Tyler beginning on Monday and lasting throughout the week. For more on this kind of work, I spoke with Royce Traylor, the crew chief for the special jobs crew.
