In this work we present chemical abundances of heavy elements ( Z > 28 ) for a homogeneous sample of 1059 stars from HARPS planet search program .
We also derive ages using parallaxes from Hipparcos and Gaia DR1 to compare the results .
We study the [ X/Fe ] ratios for different populations and compare them with models of Galactic chemical evolution .
We find that thick disk stars are chemically disjunt for Zn and Eu .
Moreover , the high-alpha metal-rich population presents an interesting behaviour , with clear overabundances of Cu and Zn and lower abundances of Y and Ba with respect to thin disk stars .
Several abundance ratios present a significant correlation with age for chemically separated thin disk stars ( regardless of their metallicity ) but thick disk stars do not present that behaviour .
Moreover , at supersolar metallicities the trends with age tend to be weaker for several elements .
