Flexible pavement design manual
What is a flexible pavement structure?
Flexible pavement structures are constructed of a flexible pavement (typically asphalt) surface layer that is placed over a treated or untreated base layer and an untreated subbase layer. Flexible pavement types and procedures are found in Chapter 630 of the Highway Design Manual (HDM).
What data is needed to engineer a flexible pavement?
The data needed to engineer a flexible pavement using the Caltrans empirical method are California R-value of the subgrade and the Traffic Index (TI) determined for the desired design life. Engineering of the flexible pavement is based on a relationship between the gravel equivalent (or equivalency) GE
How to design flexible pavement with FDR?
The general steps for designing flexible pavement with FDR are as follows: (a) Determine the FDR design thickness from the maximum existing asphalt depth and a portion of underlying material (this example assumes AB). Swelling of pulverized material must also be considered.
Where can I find rehabilitation design procedures & strategies for flexible pavement?
Rehabilitation design procedures and strategies for flexible pavement may be found in HDM Topic 635. Examples of rehabilitation designs may be found on the Department pavement website at: (1) Design Example 1 - Undrained Pavement structures Designed per California R-values of Underlying Layers (HMA/AB/AS or HMA/CTB-B/AS).
