One of the main advantages of super-renormalizable higher derivative quantum\ngravity models is the possibility to derive exact beta functions, by making\nperturbative one-loop calculations. We perform such a calculation for the\nNewton constant by using the Barvinsky-Vilkovisky trace technology. The result\nis well-defined in a large class of models of gravity in the sense that the\nrenormalization group beta functions do not depend on the gauge-fixing\ncondition. Finally, we discuss the possibility to apply the results to a large\nclass of nonlocal gravitational theories which are free of massive ghost-like\nstates at the tree-level.\n
