The 2019 Integrated Materials and Construction Practices for Concrete Pavement (IMCP) manual brings the newest information available and includes the growth and innovations that have been implemented into practice during the past 13 years. Like its predecessor, the manual provides practitioners with the best tools for designing, building, and maintaining concrete pavements using the best technologies available. More

Transportation research investigates flooding impacts

Economists say the state may see upward of $2 billion in damages from recent flooding, noting that there have been multiple breaches in levees with roads and bridges rendered unsafe or impassable.

A new technology developed by ISU engineers that has the potential to significantly boost the use of recycled materials in asphalt is earning international attention for its promising future impact to the transportation industry. The engineers, from InTrans' Asphalt Materials and Pavements Program and ISU's chemical and biological engineering department, developed a method to reduce the separation of ground tire rubber (GTR) in asphalt by mixing GTR with a polymer additive before blending it with asphalt.

REACTOR Lab research focuses on work zone safety

Imagine the stress reduction if drivers could know the extent of the work zone, where workers are currently focusing their efforts, how far the lane reduction lasts, and more, to have smoother and safer travels.
