An engineering professor at Idaho State University says the state could save money on transportation costs over time by using more concrete to build roads.

Habib Sadid completed a study for the Idaho Transportation Department earlier this year and says concrete, while more expensive to pave with than asphalt, is more durable and would require less maintenance.

Sadid says a reaction in concrete, which is made of water and cement, does makes the material susceptible to cracking.

But concrete is also more rigid and resistant to heat than asphalt, Sadid says, and would achieve transportation savings for the state in the long run
