Description

TRB's National Cooperative Highway Research Project (NCHRP) Report 538: Traffic Data Collection, Analysis, and Forecasting for Mechanistic Pavement Design provides guidance for collecting traffic data to be used in pavement design and includes softwareâ€"designated TrafLoadâ€"for analyzing traffic data and producing traffic data inputs required for mechanistic pavement analysis and design. The TrafLoad software is designed to produce traffic data for input to the 2002 AASHTO pavement design software. TrafLoad is based on a new mechanistic-empirical approach to pavement design, it relies on axle load spectra rather than equivalent single axle loads. For each of four axle types, the load spectra specify the percentages of axles falling into each of several load ranges.
