Integration of AASHTO 2002 and NJDOT PMS

February 2003

AASHTO 2002 Guide(Mechanistic-Empirical)

Design Input Levels

Allows different levels of confidence in the design procedureAllows for different levels of design budgetsThe levels are:

Level 1 (Most Accurate) – Uses primarily measured dataLevel 2 – Uses primarily estimated input dataLevel 3 (Least Accurate) – Uses assumed input data
