Publication Details

Researcher's Guide to the Long-Term Pavement Performance Layer Thickness Data Research/Reference: useful for researchers doing further work in the pavement area as well as those developing improved testing and design procedures. Includes documents of historical value.

Primary Topic: Pavement Maintenance

Description: This guide summarized the layer material type and thickness data structure in the Long-Term Pavement Performance (LTPP) database. Summaries of layer thickness within-section data variablility and constructed thickness deviations from the target thickness are also provided for LTPP sections; the guide provides several benchmark values for both of these data elements for different material types. Guidelines are also presented to search for the most appropriate thickness information for different research purposes.
