We study the production of Mueller-Navelet jets at hadron colliders in the Balitsky-Fadin-Kuraev-Lipatov framework. We show that a measurement of the relative azimuthal angle {delta}{phi} between the jets can provide a good testing ground for corrections due to next-leading logarithms (NLL). Besides the well-known azimuthal decorrelation with increasing rapidity interval {delta}{eta} between the jets, we propose to also measure this effect as a function of R=k{sub 2}/k{sub 1}, the ratio between the jet transverse momenta. Using renormalization-group improved NLL kernel, we obtain predictions for d{sigma}/d{delta}{eta}dRd{delta}{phi}. We analyze NLL-scheme and renormalization-scale uncertainties, and energy-momentum conservation effects, in order to motivate a measurement at the Tevatron and the LHC.
