About this document
Frequency Analysis for MEPDG Complex Modulus by La Foliak is a document available to read on EtoBox.
This document discusses two approaches for determining the frequency of vehicular loading on pavements - the approach used in the Mechanistic-Empirical Pavement Design Guide (MEPDG) and a novel Fourier analysis approach. The MEPDG approach is found to have errors ranging from 40-140% depending on vehicle speed and calculation depth. A Fast Fourier Transform is proposed to more accurately determine the loading frequency spectrum based on the time pulse data from moving loads. Results from the Virginia Smart
