LTPP Data Analysis: Advancement of Profile-Based Curl and Warp Analysis Using LTPP Profile Data

NCE is working with the University of Michigan to advance the innovative method for calculating curl and warp from measured longitudinal profile demonstrated in the study of a PCC Long Term Pavement Performance (LTPP) project in Arizona (http://www.fhwa.dot.gov/publications/research/infrastructure/pavements/ltpp/12068/), and for estimating the portion of roughness that can be attributed to curl and warp each time the profile is measured.  This methodology permits the study of roughness progression over a long monitoring history without the confounding influence of short-term changes in roughness.  In addition,  the potential for expanding the utility of FWD data with regards to curl and warp will also be explored.  Any strong relationships demonstrated will add a new tool to pavement designers’ toolboxes.

Leading Expert in Pavement Sustainability Joins NCE

NCE is happy to announce a new addition to our team. Thomas Van Dam, PE, PhD, FACI, LEED AP has joined NCE as a Principal in the Transportation Research Group where his expertise will expand NCE’s research capabilities and refine our pavement-related expertise. Dr. Van Dam has been actively involved in pavement-related issues at the national, regional, and state levels. His areas of expertise include sustainable civil engineering infrastructure, airport and highway pavement performance, durability, and training.

With 29 years of experience in pavement design and evaluation, concrete, materials assessment and sustainability, he has managed large projects for the FHWA, multiple state Departments of Transportation and the Innovative Pavement Research Foundation to analyze the effects of concrete properties and durability on pavement performance and has published numerous articles and papers.

Dr. Van Dam graduated from the University of Illinois-Urbana with a Bachelor of Science and Master of Science in Civil Engineering, and Doctorate in Philosophy. He’s a member of several national associations, including the American Concrete Institute, American Society of Civil Engineers, Transportation Research Board, and International Society of Concrete Pavements.

“As we are winning new pavement sustainability projects, Tom’s experience and technical skills are great assets to the growing NCE transportation research practice and to the firm,” said Claude Corvino, NCE President.
