Disintegrated carbonaceous mudstone (DCM) is a fine grain with soil-like properties produced by disintegrating carbonaceous mudstone. Notably, DCM further disintegrates and softens when exposed to water and easily collapses under stress, undermining the long-term stability of DCM-filled embankments. In this study, the unconfined compressive strength (UCS), direct shear tests, disintegration test, mercury intrusion porosimetry tests (MIP), Fourier transform infrared spectra analysis (FT-IR), X-ray diffraction analysis (XRD), and Scanning electro...
