DOI: 10.1016/j.ijprt.2018.08.006
Abstract: Abstract Crushed Rock Base (CRB) material sometimes needs to be modified typically due to the moisture susceptibility. Resilient modulus is the dominant design parameter of unbound materials and should be high enough to avoid distress… read more here.

DOI: 10.1016/j.ijthermalsci.2020.106333
Abstract: Abstract Railway embankments in permafrost regions are often affected by serious thaw settlement diseases resulting from permafrost degradation. For this reason, a novel, asymmetric crushed-rock-based embankment (ACBE) structure was employed in the construction of the… read more here.
