Pavement Thickness Design
5F-1 Design Manual Chapter 5 - Roadway Design 5F - Pavement Thickness Design Pavement Thickness Design 1 Revised: 2019 Edition A. General The AASHO road test (completed in the 1950s) and subsequent AASHTO Guide for the Design of Pavement Structures (AASHTO Design Guide) provide the basis for current Pavement Design practices. To Design a Pavement by the AASHTO method, a number of Design parameters must be determined or assumed. This section will explain the parameters required to Design the Pavement Thickness of both concrete and hot mix asphalt roadways. The same parameters can be used for input data in computer programs on Pavement determinations. The program used should be based on AASHTO Design methods. Even though the AASHTO Design Guide is several years old, it is still used throughout the industry for Pavement Thickness Design . A newer Design program called the Mechanistic-Empirical Pavement Design Guide (MEPDG) is available, however, it is costly and requires a great deal of data to be effective.
Mar 05, 2020 · blowups, frost heave, disintegration, etc. can have on loss of riding quality and serviceability. If any of these environmental effects have the potential to be present during the life cycle of the pavement, the MR should be evaluated on a season by season basis, and a seasonal modulus developed.
