Microstructure Characterization 95

3.7 Other Studies
There are many other studies focusing on the use of microstructural information for
characterizing, modeling, and simulating the macroscopic behavior of AC. The follow-
ing presents a brief review of these studies. Kutay et al. (2007, 2009) studied the distri-
bution of pore pressure and shear stress in AC with the considerations of asphalt pore
structure. Arambula et al. (2007) and Masad and Button (2004) used XCT to study the
influence of void distribution on compaction and moisture damage effects. Partl et al.
(2007) carried out a detailed study to compare the microstructure of AC with different
compaction methods. Song et al. (2005) made efforts to link XCT measurements with
damage mechanics and micromechanics applications. While it is not necessary to cite
all these applications, these efforts do indicate the consensus that researchers have
reached in characterizing the microstructure quantities into the modeling and simula-
tion of AC.
