This manual of practice presents information to guide pavement design engineers in making decisions 
and using the MEPDG for new pavement and rehabilitation design. The manual does not provide guidance 

on developing regional or local calibration factors for predicting pavement distress and smoothness.

A separate document, Standard Practicefor Conducting Local or Regional Calibration Parametersfor the 
MEPDG, provides guidance for determining the local calibration factors for both HMA and PCC pavement 
types (NCHRP, 2007.b).
