KEY FINDINGS FROM LTPP ANALYSIS 1990-1999
The Long Term Pavement Performance (LTPP) analysis program has addressed a broad array of topics - from field validation of pavement design procedures, to the study of variability in traffic and materials data, to investigating pothole repair techniques. The purpose of this document is to highlight some of the key findings from LTPP analysis studies between 1990 and 1999. These findings have been organized into the following areas: site conditions, structural features, materials, initial roughness, pavement maintenance, pavement rehabilitation, American Association of State Highway and Transportation Officials (AASHTO) design validation, and performance modeling.
