In 2004, the Ohio Department of Transportation (ODOT) conducted a test. There are two ways to build a road -- with concrete, or with asphalt – but which way is best for drivers, and for tax payers?
The project, a four-lane divided highway relocation of U.S. 30 in Wayne County, was designed to test the concept of perpetual pavement.
Perpetual pavement has been touted as asphalt that can last several decades with little need for reconstruction.
Professionally-produced by the Portland Cement Association (PCA), the video below shows an aerial view of a section of US-30 in Ohio where in 2004 one side of the highway was paved in asphalt and the other side paved in concrete.
So which material provided the best return on investment? After 11 years, there is a clear breakdown of the asphalt pavement while the concrete pavement appears in excellent condition. The soil, contractor, length of road, and weather conditions were identical while the durability was not. The clip is a real-world example of the superiority of concrete paving and may persuade lawmakers and local decision makers to choose concrete.
The conclusion of the test: Chose concrete, it passes the test.
