  We perform an exclusive study of the anomalous $Wtb$ interaction in the
context of LHC. The limits on $Wtb$ anomalous couplings have been estimated via
the measurements of the top-quark decay width and cross-section as well as
production asymmetries in case the CP is violated. Our investigations reveal
that the upper bounds on $(|C_L|, |C_R|)$ would be of about (1.82, 0.03)
$\times 10^{-4}$ at $2.5 \sigma$ C.L., for the already collected data at the
LHC with $\sqrt{S} = 13$ TeV for an integrated luminosity of 139 fb$^{-1}$. The
corresponding limits for future hadron colliders, namely, High Luminosity LHC
(HL-LHC), High Energy LHC (HE-LHC) and Future Circular Collider (FCC-hh) for
the projected luminosities of 3 ab$^{-1}$, 12 ab$^{-1}$ and 30 ab$^{-1}$ are
found to be to $(0.81, 0.006)\times 10^{-4}$, $(0.44, 0.0017)\times 10^{-4}$
and $(0.21, 0.0004)\times 10^{-4}$ respectively at 2.5$\sigma$ C. L..
