Extreme summer heat can bring cracked, uneven and "buckling" pavement to roads.
The Virginia Department of Transportation asks drivers - especially motorcyclists - be on the lookout for problem spots and work zones in case crews need to make emergency repairs. Road buckling is caused during periods of high temperatures when concrete expands. Buckling is prevalent in the mid-Atlantic states, including Virginia.
VDOT crews are on special alert for emergency repairs this weekend as temperatures are expected to reach in excess of 100 degrees.
