Micromechanics-based complex modulus prediction of crumb rubber modified bitumen considering interparticle interactions

Crumb rubber modified bitumen (CRMB) can be regarded as a binary composite system in which swollen particles are embedded the matrix. The current study aims to further improve prediction accuracy of micromechanical models for CRMB by considering interparticle interactions. To accomplish this goal, two different strategies were used. Firstly, (n+1)-phase model was applied multilayer properties particles. Secondly, new scheme called J-C used account interaction issue. Results show that slightly increase accuracy but underestimation complex modulus at lower frequencies remains unsolved. remedies low-frequency range other and provides an overall improvement relative properly addressing interactions from perspective particle configuration.
