We investigate Higgs-radion mixing scenario through single radion photoproduction process $pp\to p\gamma p\to pRqX$ at the LHC where $X$ represents the remnants of one of the initial protons. We consider high luminosity values of $L_{ int}=200\;fb^{ -1}$, $500\;fb^{ -1}$ and $3000\;fb^{ -1}$. We obtain bounds on the mixing parameter space by considering $R\to \gamma\gamma$, $R\to W^+ W^-$ and $R\to ZZ$ decay channels of the radion as the signal. We also perform a similar analysis for a 100 TeV future proton-proton collider and compare its potential with that of LHC.
