Difference Between Concrete and Asphalt Roads •

2010-4-25  4. Concrete roads are not damaged from oil leaks, like asphalt roads. 5. Concrete roads come with a higher paving cost than asphalt roads. Moreover, it takes less time to lay an asphalt road than a concrete road. 6. Asphalt roads have better skid resistance and provide good traction. Snow melts faster on asphalt roads than on concrete roads.
