Impact of New-Generation Wide Base Tires on Pavement Investigated

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.

A New Tool for Pavement Evaluation

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 and bridge decks 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).

Ongoing Study Seeks to Improve Hot-Mix Asphalt Performance

ICT leads the way in the area of sustainable asphalt pavement. In an ongoing effort to maximize performance of hot-mix asphalt (HMA) containing higher amounts of recycled materials, IDOT and ICT continue work on Construction and Performance Monitoring of Various Asphalt Mixes (R27-161). A second interim report on the project was recently published.

Field Installation Guidelines Developed for Asphalt Crack Sealants

Illinois Center for Transportation researchers have recently developed field installation guidelines to help pavement maintenance professionals select, install, and evaluate hot-poured crack sealant treatments for flexible pavements.

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

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.
