Abstract The increasing attention over cold recycling technologies as sustainable paving solutions requires a proper characterisation in terms of complex modulus for supporting the pavement design. Among recycled materials, cement bitumen treated materials (CBTM) benefit from presence both bituminous and cementitious binders. This research aims at characterising CBTM mixtures produced with thre...

To assess the mechanical response under traffic of asphalt mixtures, a typical practice is to perform complex modulus test. In this work, test reproduced numerically for an mixture by 3D simulations carried out with LMGC90 code. A viscoelastic contact law used handle interaction between particles irregular shapes. The numerical aggregates were generated using particle size distribution (PSD), f...

Quick extraction of the largest modulus eigenvalues of a real antisymmetric matrix is important for some engineering applications. As neural network runs in concurrent and asynchronous manner in essence, using it to complete this calculation can achieve high speed. This paper introduces a concise functional neural network (FNN), which can be equivalently transformed into a complex differential ...

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 p...
