7/7/11 – Every summer we hear about roads buckling due to the heat and this summer is no exception. In the past week Highway 151 and Highway 33 both have seen cement failures that Dodge County Highway Commissioner Brian Field says were caused by high temperatures. He says the heat causes the cement slabs to expand and push against each other up into the air causing them to fail. Field says the failures are time consuming and costly to fix. Each year the county sees about 15 instances of the road buckling, mostly on the state highway that are built with concrete.
