Title: ANOTHER CASE CRACKED : ILLINOIS PERSUADED TO TRY PERPETUAL ASPHALT ON PART OF HEAVILY TRUCKED I-70
Abstract: A heavily trucked 20-mile segment of I-70 in eastern Illinois that had asphalt overlay on a concrete base, had sustained so much deep, age- related damage that it needed to be totally reconstructed. This article describes how the Illinois Asphalt Pavement Association (IAPA) convinced the skeptical Illinois Department of Transportation (IDOT) that reconstructing the freeway segment as an asphalt pavement and rubblizing the concrete pavement to serve as a base for the asphalt would be the most cost-effective solution. The IDOT was also faced with a state legislation that now required the state to start building long-lasting pavements as demonstration projects. The objectives were to have pavements built that would last 30 years, need less repair, and present less traffic disruption. Warranties would also be offered on the pavements for their first five years. The final solution was a compromise in which 9 miles of the roadway would be paved in concrete, while close to 11 miles would have an asphalt surface. Both types of pavement would also come wit the five year warranty.
