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(2)/k(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.
