For construction companies working on highway and road projects, there are a unique set of requirements in order to complete the job. However, for some project owners, nothing is more important than the quality of the job, as infrastructure needs to be safe and secure for drivers.
The U.S. FHWA (Federal Highway Admin.), www.fhwa.dot.gov, Washington, D.C., the AASHTO (American Assn. of State Highway and Transportation Officials), www.transportation.org, Washington, D.C., and the TRB (Transportation Research Board), www.trb.org, Washington, D.C., recently came together in an effort to reduce costs and improve pavement quality.
SHRP2 (Strategic Highway Research Program)—an initiative committed to delivering solutions that address growing congestion and aging infrastructure while increasing roadway and construction safety—will begin accepting applications from state departments of transportation that want to use realtime concrete pavement smoothness to speed projects and improve quality.
On a typical project, contractors need to wait for concrete pavement to gain strength before evaluating the smoothness. But with new tools, they will be able to make monitor the smoothness of freshly placed concrete, which will improve quality and operations.
The two new devices—the GOMACO Smoothness Indicator and the Ames Engineering Real Time Profiler—measure pavement smoothness. The products were selected after research and evaluation performed by pavement engineering firm The Transtec Group, www.thetranstecgroup.com, Austin, Texas.
For any construction project, quick delivery and a quality job are always two of the most important factors. Balancing the two can sometimes be challenging. For infrastructure construction firms, these new devices can help by providing access to information about the realtime pavement smoothness, which will improve quality on the project and ensure it is delivered in a timely fashion.
