  12 Bootis is a spectroscopic binary whose visual orbit has been resolved by
interferometry. Though the physical parameters of the system have been
determined with an excellent precision, the theoretical modelling of the
components is still uncertain. We study the capability of solar-like
oscillations to distinguish between calibrated models of the system obtained by
including in the stellar modelling different mixing processes. We consider
different scenarios for the chemical transport processes: classical
overshooting, microscopic diffusion and turbulent mixing. For each of them we
calibrate the stellar models of 12 Boo A and B by fitting the available
observational constraints by means of a Levenberg-Marquardt minimization
algorithm, and finally, we analyze the asteroseismic properties of different
calibrated models. Several solutions with 12 Boo A in (or close to) post-main
sequence and 12 Boo B on main sequence are found by assuming a thickness of the
overshooting layer between 0.06 and 0.23 the pressure scale height. Solutions
with both components on the main sequence can be found only by assuming an
overshoot larger in the primary than in the secondary, or a more efficient
central mixing for 12 Boo A than for 12 Boo B. We show that the detection of
solar-like oscillations expected in these stars would allow to distinguish
between different scenarios and provide therefore an estimation of the
overshooting parameters and of the properties of extra-mixing processes.
