Chapter 4 Mechanistic Analysis of Modifying SMA Mixtures in Flexible Pavements
The responses for estimating the improvement in service life of the pavement or reduction in thickness of SMA and base layer for the same service life due to modification the SMA mixtures are determined and discussed in this chapter. In addition, this chapter compares the strain and displacement fields of an isotropic and an anisotropic of polymers and ST-modifying the SMA layer in flexible pavement using FE simulation.
