Damage Caused by New-Generation Wide Base Tires Investigated

Published July 5, 2017

Even though they’re known to provide more environmental benefits than conventional dual-tire assemblies, wide-base tires are often associated with higher pavement responses and more damage to roads infrastructure. However, scientific literature lacks in-depth evaluation of pavement damages and the benefits attributed to each tire type.Read More

Awards and Honors

Published July 5, 2017

The following ICT-affiliated researchers have recently been recognized by the research community with the following awards:

  1. Southern Illinois University Edwardsville (SIUE) graduate student Md. Toushik Ahme Niloy, who has been assisting with ICT/IDOT project “Design of Living Barriers to Reduce the Impact of Snow Drifts on Illinois Freeways” received the SIUE Graduate School Dean Steve Hanson Symposium Poster Award for his poster “Actuated Signal timing Optimization for a No-Notice Evacuation: A Simulation Study of Residents Near the Phillips 66 Oil Refinery in Wood River, Illinois.”
  2. Mani Golparvar Fard, associate professor in the Department of Civil and Environmental Engineering at the University of Illinois at Urbana-Champaign was awarded the Hojjat Adeli Award for Innovation in Computing for his paper: Dimitrov, A., Gu, R., and Golparvar-Fard, M. (2016), “Non Uniform B-Spline Surface Fitting from Unordered 3D Point Clouds for As-Built Modeling,” Computer-Aided Civil and Infrastructure Engineering, 31:7, pp. 483-498).
  3. Associate Professor Ryan Fries of Southern Illinois Edwardsville has received both the 2017 University of Delaware Department of Civil engineering Citation for Outstanding Achievement Award and the Illinois-Indiana Region American Society of Engineers Education Outstanding Representative Award.
  4. Dr. Hao Wang was promoted to Associate Professor in the Civil and Environmental Engineering Department at Rutgers University. Dr. Wang also received Rutger’s ASCE Chapter Distinguished Research Award.

Recent ICT Reports and New Projects

Published July 5, 2017

The following reports from recently completed IDOT-sponsored projects are now available on ICT’s website.

R27-045-T1: Evaluation of 3-D Laser Scanning Equipment: 2016 Interim Report. This interim report details an evaluation of the Trimble TX5 3D laster scanning unit to determine the tangible costs and the manpower savings realized by using this equipment in place of or in conjunction with conventional surveying methods. Two projects in IDOT District 8 were studied, one using the laser scanner, one using convential surveying techniques, in order to compare manpower requirements. In addition, other project were used to test the scanner for other purposes, such as surface topography mapping of bridge decks, bridge beam deflection scans, and detailed surface mapping of various structures.  Further testing of this equipment is expected to take place in the coming construction season.

R27-152: Development of a Proposed Overweight Vehicle Permit Fee Structure in Illinois. The objective of this study was to revise the current permit system for the State of Illinois. Parts of this current system had not been updated in 30 years, so researchers looked at the impacts of overweight vehicles on bridges and pavements, and in traffic safety situations, and used state-of-the-art prediction/classification algorithms to produce a realistic, up-to-date assessment of the impact of overweight vehicles. The report details the methods and final fee determination researchers produced by combining the new data with known data on the miles traveled and axel and weight information used by the permitting system.

R27-172: Roadway Lighting’s Impact on Altering Soybean Growth: Volume 1. This project sought to measure the impacts of roadway lighting on soybean production. By measuring height, reproductive stage, plant moisture content, and other factors at seven different sites, researchers found strong evidence that roadway lighting had a significant impact on soybean crops and recommended ways to mitigate the effects.

R27-141: Effective Post-Construction Best Management Practices (BMPs) to Infiltrate and Retain Stormwater Run-off. Using a combination of field observations and computer simulations, researchers evaluated three types of storm-water prevention techniques, and combined that information with life-cycle analysis costs, in order to identify the most cost-effective solutions for managing runoff in post-construction highways. They also conducted full-scale field tests of bioswales and infiltration trenches. These different approaches provide key insights for developing guidelines for cost-effective best-management practices to control stormwater runoff.

R27-SP31: Evaluation of I-FIT Results and Machine Variability using MnRoad Test Track Mixtures. Researchers evaluated machines in various configurations for performing the Illinois Flexible Index Test (I-FIT). By comparing three machines and eight different asphalt concrete mixtures, they determined that the I-FIT test was stastisically independent of the equipment used for the procedure.

Additionally, the ICT Executive Committee has approved two new projects:

  • Evaluation of Various Tack Coat Materials Using Interface Shear Device and Recommendations on a Simplified Device (started May 1, 2017)
  • Behavior of Epoxy Coated Textured Reinforcement Bars (started May 15, 2017)
