NON-LINEAR MASTIC CHARACTERISTICS BASED ON THE MODIFIED MSCR (MULTIPLE STRESS CREEP RECOVERY) TEST

Abstrakt

Mastic containing asphalt in its composition is an example of a viscoelastic material. It is an effective binder in asphalt. It consists of a filler (<0.063 mm) and asphalt mixed in the right proportions. Just like in asphalt, its response depends on the temperature level, the load and stress time. Changing the stress stiffness of the mastic affects the non-linear course of the stress-strain relationship. Modelling of the non-linear course of the mastic response for any stress history was performed using a single-integral Schapery equation. Two mastic composites made using filler to asphalt 2:1 ratio, was used in the tests. In addition, the contents of the filler, in one of the compositions, was enriched with hydrated lime in an amount of 15% in relation to the mass of the lime filler. It was found that the use of non-linear viscoelasticity model describes, in a comprehensive manner, the change in strain over time with different stress histories. In addition, hydrated lime reduced strains in the mastic compared to a composition consisting of limestone dust only.
