R27-ALS Accelerated Transportation Loading Assembly Repairs and Upgrades Project 6/30/2024 Advanced Innovation Services LLC (AIS) is pleased to provide the University of Illinois (U of I) a proposal to upgrade the ATLAS 80 Accelerated Pavement Test Machine (APTM) located at the Advanced Transportation Research Engineering Laboratory (ATREL) in Rantoul Illinois. The proposed upgrades will provide new capabilities, maintain current capabilities and ensure ATLAS is operational for years to come. https://apps.ict.illinois.edu/projects/view.asp?id=2435
R27-SP65 Low-Clearance Early Warning Devices 7/31/2024 The state of Illinois recently passed legislation requiring IDOT to establish a pilot program to install devices on or near bridges over roadways that warn drivers of low clearances. The aim of this project is to help identify potentially effective devices and technologies that can be installed to help reduce bridge strikes in Illinois. Researchers will examine various technologies and devices used to provide early warning of low-clearance structures as well as their effectiveness. Decreasing the number of bridge strikes reduces costly damage to state property and reduces road and lane closures caused by damaged structures that cannot be immediately repaired.

R27-233 Mechanistic - Empirical Design Procedures for Flexible Pavements 5/15/2024 Design procedures and policies for flexible (asphalt) pavements are continually evolving. This project reviewed the Illinois Department of Transportation’s current design method and policy documents. Researchers discovered via lab testing of contemporary hot-mix asphalt mixtures that changes to design inputs may be needed to ensure that the design processes reflect the latest technology. They recommended further research to characterize IDOT mixtures and provide guidance on policy updates. Improved pavement designs are expected to result in cost savings and improved long-term pavement performance.
R27-210 Cone Penetration Testing (CPT) for Illinois Subsurface Characterization and Geotechnical Design 5/31/2024 Engineers use the cone penetration test to determine detailed information about the properties and strength parameters of soil. This test, which collects data continuously, is faster and provides more consistent data than the currently used standard penetration test, in which a hollow stem auger is positioned into the ground at 2.5- to 5-foot intervals to retrieve soil samples. The goal of this project is to develop guidelines and a manual for the cone penetration test. These resources will help the Illinois Department of Transportation obtain more reliable data and lower the risk in roadway and geotechnical designs, thereby red...
R27-SP59 Field Performance of Unacceptable Hot Mix Asphalt Test Parameters 5/31/2024 IDOT uses mixture volumetric and in-place density test parameters in the hot-mix asphalt quality management programs for acceptance. In the acceptance process, IDOT has acceptable limits associated with four test parameters: air voids, field voids in the mineral aggregate, in-place density and dust to asphalt binder ratio. The goal of this project is to evaluate the relationship between field performance and mixture volumetric and in-place density test parameters (including the acceptable limits parameters) used in the IDOT acceptance process. Additionally, researchers will develop a framework to monitor hot-mix asphalt field performance in the future.
