Research Leads to New Understanding of Integral Abutment Bridges

Integral abutment bridges are constructed without expansion joints. Due to the high maintenance costs associated with expansion joints—as a result of water seeping through the joints and causing damage to the beams and bearings at joint locations—integral abutment bridges (IAB) have become increasingly popular in the past 30 years, not only because of the economic advantages of these structures, but also because of their proven functionality and durability.

IDOT Adapts Construction Staking to Modern Technology

In a world that is increasingly shaped by improving digital technologies, the past few decades brought great advances in technology for highway construction and engineering. Such advances almost always aim to reduce costs and improve quality. For instance, incorporating technologies, such as the global positioning system (GPS) and civil information modeling (CIM), among others, in highway construction is believed to lead to improvements in construction quality while reducing construction time and cost.

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.
