A New Tool for Concrete Infrastructure Evaluation

Published May 22, 2017

Repairs and maintenance for the transportation infrastructure of Illinois present a potentially huge cost to the state. In order to test new technology that  could provide “effective, efficient, economical, and rapid data collection” of pavements, bridge decks, and other concrete structural elements for the purpose of evaluation of their condition and the need for repairs, IDOT teamed up with ICT in a recent project, Ultrasonic Imaging for Concrete Infrastructure Condition Assessment and Quality Assurance (R27-146).Read More

Ongoing Study Seeks to Improve Hot-Mix Asphalt Performance

Published April 1, 2017

In an ongoing effort to maximize performance of hot-mix asphalt (HMA) containing higher amounts of recycled materials, IDOT and ICT started a project entitled Construction and Performance Monitoring of Various Asphalt Mixes (R27-161) in 2014. This effort is part of a larger goal that aims to improve pavements built using recycled materials to enhance their sustainability. A second interim report on the project was recently publishedRead More

Speed Harmonization: ICT Research Helps IDOT Improve Safety on Rural Roadways

Published April 1, 2017

Current geometric design of roadway elements is based primarily on the design speed. The design speed is used by roadway engineers to design appropriate safety elements such as vertical and horizontal curves, stopping sight distance, and guardrail needs. On rural highways, operating speed is often higher than the design speed, which may become problematic from a safety standpoint. In rural settings, there are also more free-flowing traffic conditions with limited enforcement opportunities. These circumstances often lead to increased crashes.Read More

Improving the Effectiveness of Smart Work Zone Technologies

Published January 23, 2017

A recently completed project sponsored by IDOT and conducted by ICT investigated the effectiveness of sensor network systems for detecting traffic jams or stopped traffic, estimating travel times and delays for motorists, and estimating speed of vehicles in and approaching roadway work zones.Read More
