First International Conference on Transportation Construction Management: New Solutions in Successful Project Delivery
Nearly 300 attendees met to discuss new challenges and new solutions in successful transportation project delivery at the First International Conference on Transportation Construction Management (TCM), held February 10-12, 2009, in Orlando, Florida. Featured topics included accelerated construction technology transfer, public-private partnerships, risk management, and contractor prequalification and measurements.
FHWA Launches Online ASR Reference Center
The Federal Highway Administration (FHWA) has launched a new online Alkali-Silica Reactivity (ASR) Reference Center (www.fhwa.dot.gov/pavement/concrete/asr/reference.cfm), providing users with one-stop access to ASR-related information. ASR occurs when silica in some aggregates and alkalis in cement combine with water to form a gel-like substance. As the gel absorbs water and expands, it causes the concrete to crack. Over time, this can lead to premature deterioration and a reduction in service life.
FHWA’s ACTT Toolkit: Bringing the Power of Accelerated Construction Straight to You
A new toolkit is available online and on CD to assist State highway agencies in hosting Accelerated Construction Technology Transfer (ACTT) workshops.
