| Project Title: |
| |
Performance of I-57 Recycled Concrete Pavement
|
| Start Date:
1/1/2008
|
| End Date:
12/31/2008
|
| Summary of Project: |
| |
The state of Illinois first used recycled concrete aggregate (RCA) twenty years ago to rehabilitate a section of I-57. This project summarizes and documents this pavement section's performance and compares it to similarly aged and trafficked continuously reinforced concrete pavements (CRCP) in Illinois. The project's tasks included: a structural evaluation of I-57 CRCP using distress surveys collected by IDOT, a functional evaluation of I-57 CRCP using friction and IRI data collected by IDOT, and an evaluation to check for the presence of alkali-silica reaction (ASR) or any other deleterious reaction.
|
|
Objective of Project: |
| |
The research objectives are to summarize and document the twenty-year structural and functional performance of the I-57 CRCP inlay that utilized recycled concrete as the primary coarse and fine aggregates.
|
| Expected Outcome: |

IDOT, consultants
