Chapter 5: Flexible Pavement Design

Section 1: Overview

This chapter documents the policy for designing flexible pavements. The following topics are discussed:
  • types of flexible pavements,
  • design parameters used in FPS 21 (analytical flexible pavement design procedure),
  • FPS 21 modulus inputs and backcalculation methodology,
  • pavement detours and widening, and
  • design of perpetual pavements.
