Influence of hydrated lime on linear viscoelastic properties of mastics

Résumé

An ongoing study on influence of hydrated lime on mechanical properties of bituminous mixtures is carried out in the framework of collaboration between the LHOIST Group and University of Lyon /ENTPE. In this paper we focus on linear viscoelastic properties of mastic. Different mastics were produced with the same bitumen penetration grade, same bitumen content and different hydrated lime content. Hydrated lime replaces a part of limestone filler (the same mass of removed filler for the same mass of added hydrated lime). Linear Viscoelastic properties of both produced mastics and bitumen were determined using a dynamic shear rheometer (DSR). First results and analyses are presented in this paper. The Time-Temperature Superposition Principle (TTSP) was verified with good approximation. The 2S2P1D model developed by ENTPE team was used for modelling linear viscoelastic properties of bitumen and mastics. Effect of hydrated lime is discussed.
