These new AASHTO publications represent significant updates to two important previous publications. From the AASHTO website:
“LRFD Specifications for Structural Supports for Highway Signs, Luminaires, and Traffic Signals, 1st Edition
The first edition of the LRFD Specifications for Structural Supports for Highway Signs, Luminaires, and Traffic Signals incorporates and builds upon the design specifications found in the Sixth Edition of Standard Specifications for Structural Supports for Highway Signs, Luminaires, and Traffic Signals, which it supersedes. The specification includes current research on LRFD calibration, loads, and resistances plus relevant specifications from other AASHTO documents. Completely new sections on Fabrication, Construction, Inspection, and Asset Management based upon best practices have also been added.
Mechanistic-Empirical Pavement Design Guide: A Manual of Practice, 2nd Edition
This manual describes a pavement design methodology, termed mechanistic-empirical (M-E) pavement design, that represents a major change from the pavement design methods in practice today. Based on engineering mechanics that have been validated through extensive road test performance data, the manual presents information necessary for pavement design engineers to begin using the MEPDG design and analysis method.”
Both books are available for checkout at the NDOT Research Library.
