State transportation officials are urging drivers to watch out for pavement problems as the high temperatures heat the highways.

Officials say pavement blowups happen when thermal expansion forces the pavement to buckle and shatter.

A blowup can happen anytime without warning. Officials urge drivers to pay special attention to highways when driving during afternoons when the mercury climbs to 90-degrees or higher.

The DOT says many of the blowups result in a pothole or with small chunks of concrete on the pavement, and they take time to repair.

Officials say the repairs cost an average of $400,000 each year.
