Abstract

This report summarizes activities undertaken to support and ensure that the Illinois Department of Transportation utilizes the best demonstrated available technology for design and construction of full-depth hot-mix asphalt (HMA) pavements and HMA pavements on rubblized Portland cement concrete pavement (PCCP). To achieve this goal, the researchers reviewed pavement design and special provisions for full-depth asphalt and rubblization projects as well as full-depth asphalt and rubblization project performance via condition surveys and deflection measurements. They also modified design inputs as needed from the review of literature and responded to specific issues related to full-depth asphalt and rubblization design and construction. The researchers studied 32 rubblization projects on the interstate system and found this rehabilitation technique is providing good to excellent performance that exceeds design expectations. They provided input on proposed changes to full-depth hot-mix asphalt pavement on rubblized PCCP specifications as well as provided input on the RoadTec 1105e material transfer device. Analysis of traffic speed deflectometer data obtained on several hot-mix asphalt and rubblized pavements resulted in the development of analysis algorithms.
