ACPA participated in an Expert Task Group for the FHWA Long-Term Infrastructure R&D program.  Leif Wathne participated in the long-term pavement performance (LTPP) group. A second group focuses on long-term bridge performance (LTBP). 

Leif Wathne participated in the meeting, which covered a range of topics related to long-term pavement research. Among the key questions the pavement performance group

• How has LTPP data fundamentally improved understanding of pavement performance?
• What are the critical, high-priority knowledge gaps?
• What are the top 3 analysis projects to submit to NCHRP?
• What is the ETG’s top priority to be funded by LTPP?

The meeting was held last week at the National Academies of Sciences in Washington, DC.
