New ICT-IDOT projects

The following research projects have recently started:

R27-190: Evaluation of Various Products for Perimeter Barrier (Started 5/16/18)

The project objectives are to: 1) Conduct the field tests and collect samples to analyze the effectiveness of various perimeter barrier products 2) Review and suggest proper installation techniques for the products 3) Examine the water samples, specifically for turbidity and sediment concentration before and after the products 4) Quantify the sediment retained by various products so that it can provide statistical support for management decision 5) Assist IDOT in maintaining the perimeter barrier approved product list.

R27-192: Maritime Freight Data Collection System and Database to Support Performance Measures and Market Analyses (Started 5/16/18)

The objectives of this research are to: 1) Create an integrated, comprehensive, and maintainable database of maritime freight to, from, and through Illinois and corresponding performance metrics; and 2) Demonstrate the use of the database and metrics for IDOT planning and programming purposes such as market analysis and performance-based funding and project selection practices with a series of recommended evaluation/priority/ranking criteria.

R27-193-1: Flexible Pavement Recycling Techniques (Started 7/16/18)

The objective of this project is to further develop and refine specifications, procedures, and policies for flexible pavements recycling techniques (CCPR & FDRC).

R27-193-2: Flexible Pavement Design (Full-Depth and Rubblization) (Started 7/16/18)

Project activities will focus on utilizing Best Demonstrated Available Technology (BDAT) as related to Full-Depth Hot-Mix Asphalt (HMA) pavements and Rubblized PCCP with HMA overlay.

R27-194: Evaluation of Spatial and Temporal Load Distribution in Steel Bridge Superstructures (Started 7/1/18)

The goal of this research is to improve the understanding of three-dimensional load distribution, including time variation, in steel girder bridges through field monitoring and numerical modeling. The project will provide new knowledge about sources of girder stress that will inform future design procedures and improve safety and economy in IDOT’s bridges.

R27-197: Characterization of the Bond Strength of Textured Epoxy-Coated (TEC) Reinforcement Bars (Phase 2) (Started 7/16/18)

The objectives of this research are to: 1) Study the quality of the epoxy coatings bond and whether it is sensitive to the manufacturing process. 2) Investigate the effect of roughness and surface profile on the bond behavior of Textured Epoxy-Coated (TEC) rebars. 3) Explore practical options for examining roughness of TEC rebars in the field. 4) Examine the impact of using TEC rebars on the crack patterns during curing (due to shrinkage) and ultimate stages. 5) Determine an expression for the development length of TEC rebars in flexural members.

R27-198: Development of Guidelines for Implementation of Horizontal Directional Drilling (Started 7/1/18)

The objectives of this study are to: 1) Document performance of recent selected Horizontal Directional Drilling (HDD) installations in Illinois and elsewhere if available. 2) Conduct a survey of selected HDD contractors regarding their experience and needs, and 3) Develop guidelines with quantitative metrics that can be used as the basis for evaluating proposed HDD installations for IDOT permit review and construction projects. Issues to be addressed are to define the conditions under which HDD is feasible and can be allowed. This includes addressing current IDOT concerns regarding aspects of HDD during construction and for the lifetime of the installation.
