The Illinois Department of Transportation (IDOT) is revising current specifications for opening new PCC (Portland cement concrete) pavements to traffic. These revisions will help keep closure times at a minimum by specifying ...

Temperature significantly affects the performance of UPS systems. Four different UPS systems were evaluated at sub-zero temperatures and hot temperatures from -25 °C to +72 °C (-13 °F to +162 °F). At high temperatures, ...

Performance analyses of newly constructed linear BMPs in retaining stormwater run-off from 1 in. precipitation in post-construction highway applications and urban areas were conducted using numerical simulations and field ...

From 2006 to 2014, ten right‐turn approaches in the Peoria, Illinois, area were selected and reconstructed with a modified right‐turn lane design. The major purpose of the modified design was to improve the line of sight ...

During bridge deck construction, construction loads are transferred through the overhang-formwork system into the girder system, resulting in significant torsional moments acting on the exterior girder. In some cases, these ...

The U.S. Department of Health and Human Services has shown that America’s senior population has been growing and will almost double by 2030. This trend continues to challenge researchers who are looking to increase ...

This research was performed to enhance the software tool (Illinois Construction Scheduling Expert System, ICSES) developed in Phase I of this project (ICT project R27-86) by mining data collected on IDOT construction ...

This report provides two sets of equations for estimating peak discharge quantiles at annual exceedance probabilities (AEPs) of 0.50, 0.20, 0.10, 0.04, 0.02, 0.01, 0.005, and 0.002 (recurrence intervals of 2, 5, 10, 25, ...

The project evaluated two pre-manufactured pavement marking tapes (380AW and XRP-R) over three winter seasons at two different Illinois DOT locations (central and southern Illinois). The two products were installed on ...

Serving as a windbreak, properly sited and designed snow fences have been proven effective in mitigating the negative impacts of blowing snow. To achieve the best snow-control effects, the ideal locations for snow fences ...
