![]() ![]() ![]() Incorporation of crack load transfer efficiency or LTE for flexible pavements.Updated climate discussion for Modern Era Retrospective Reanalysis and North American Regional Reanalysis data.Addition of five “level 3” default distributions for normalized axle load spectra, known as NALS.Addition of non-structural preventative maintenance treatment consideration for flexible and rigid pavements.New flexible and semi-rigid pavement global calibration coefficients.New mechanistic-empirical model for short jointed plain concrete pavement or SJPCP overlays of flexible pavements.New fracture mechanics-based model for reflective cracking in asphalt overlays over flexible, semi-rigid and rigid pavements.Major revisions in the third edition of this manual include: This revised manual provides an overview of the methodology termed mechanistic-empirical or “M-E” pavement design.īased on engineering mechanics that have been validated through extensive road test performance data, the manual references AASHTOWare Pavement ME Design and M-E Pavement – crafted as part of the AASHTO’s software development program. The American Association of State Highway and Transportation Officials has released a new publication: Mechanistic-Empirical Pavement Design Guide: A Manual of Practice, 3rd Edition. ![]()
