Comprehensive Truck Size and Weight Limits Study: Pavement Comparative Analysis Technical Report
Appendix K: Compilation of Base Case Pavement Analysis Tables
The following tables present a tabulation of the number of years (service life) until predicted distress levels reach a specified trigger value at the mean predicted distress values. Note that the individual pavement sections considered in the 2014 CTSW study analysis, presented here and in Appendices L, M, and N, cover a range of pavement types and design details, climates, traffic levels, axle loads, and other key factors. Since a small number of sections were used in each climate zone and traffic range, the results cannot be used to assess the relative effects of climate or traffic level. Together, the range of sections produces a plausible assessment of the relative effects of each scenario within the parameters and assumptions of the analysis.
