Cementitiously Stabilized Materials

Cementitiously stabilized materials (CSM) includes lean concrete base, cement stabilized aggregate, and soil stabilized with cement, lime, fly ash, or combinations thereof in the subgrade, sub-base, and base layers of pavement structures.

CSM are special kind of non-asphalt bound materials. These materials undergo curing, bottom up fatigue damage, and top down crushing damage. The models for CSM are taken from the paper by Li et al (2019). The cementitious material fatigue damage model replaces the non-asphaltic fatigue damage model.

These materials tend to be stable and do not experience permanent deformation.
