  Due to its high mass top quarks decay before top-flavoured hadrons can be
formed. This feature yields experimental access to the top quark polarization
and production asymmetries. The large top quark sample moreover enables
measurements of other properties, such as the W-boson branching ratios and
helicity, and fragmentation functions of the bottom quarks. In this
contribution, recent measurements of top-quark spin properties at the LHC are
presented, including in particular the first evidence of the charge asymmetry
in $t\bar{t}$ production (ATLAS), the charge asymmetry in a boosted regime
(CMS) and the first measurement of the charge asymmetry in $t\bar{t}+W$
(ATLAS).
