This paper focuses on the meso-scale computational modeling of the thermo-mechanical response of asphalt concrete mixes using for the first time a compressive coupled thermo-viscoelastic, thermo-viscoplastic, and thermo-viscodamage constitutive model. Asphalt concrete is represented by two-dimensional images of the microstructure that consist of three phases: aggregate, matrix, and interfacial transmission zone (ITZ). The matrix and ITZ are considered as thermo-viscoelastic, thermo-viscoplastic, and thermo-viscodamaged materials, while the aggregate is considered to be elastic. The effects of variation in aggregate shape, distribution, volume fraction, ITZ strength, strain rate, and temperature on the degradation and micro-damage patterns in asphalt concrete are investigated under uniaxial tension, compression, and repeated creep-recovery loading conditions. It is concluded that the aggregate volume fraction and distribution significantly influence the micromechanical response of asphalt concrete. Additionally, the results indicate that the constitutive model presented in this paper can provide a computational tool for predicting the overall macroscopic behavior of asphalt concrete based on the distribution of the microstructure constituents and the properties of these constituents. As such, the results of this computational model can be used to guide the design of asphalt concrete mixtures.

“…Therefore, a study that would consider the effects of the size and shape on the outcomes of the asphalt cohesion and adhesion can itself be complex but doable. Considering the complexity of the mix, several other studies considered circular shape small-scale AC models 9), 15) . A very thin matrix layer was considered on the aggregate and the layer behavior was assumed to be elastic.…”

This study was conducted to understand asphalt concrete (AC) behavior using finite element method (FEM) modeling considering wet and dry aggregate-binder mixture. A small-scale FEM model of AC was developed considering an aggregate coated with matrix materials. Maximum stress criteria and surfacebased traction-separation law were applied on matrix materials and matrix-aggregate interface, respectively, using ABAQUS. Results indicated that shear stress reached its capacity and damage initiated earlier in wet matrix materials due to moisture and caused higher damage. Moisture caused 62.80% more damage in matrix materials when compared with dry matrix materials. Damage occurred at the matrix-aggregate interface when shear contact stress reached its capacity and interfacial debonding occurred at the damaged locations. Moisture caused 17.45% more debonding at the interface region compared to the dry matrix. However, wet aggregate did not change the damage scenario at the matrix-aggregate interface when compared with dry aggregate. Matrix materials slid horizontally (i.e., relative displacement) and moved vertically (i.e., contact opening) at the debonding locations. The strong rebound effect of dry matrix was the reason for the higher relative displacement and contact opening at the damaged locations.

In this paper, the inner model structure was created using the average particle size approach, which is discussed in Mo et al (2008) paper, where particles less than 1 mm in size are not taken in to account; for the average particle size calculation, the average particle size is: where: n is the total number of particles in the specimen; d is the average diameter of a particle, mm; d ii-particle size, mm; w i -percentage distribution by mass; ( ) 1 / 2; Fig. 10.…”

Abstract. This paper addresses simulation of asphalt on the macroscopic scale, using the Discrete Element Model (DEM). Asphalt mixture is considered as a particulate solid composed of relatively stiff deformable layered spherical particles embedded into a homogenised matrix. The discrete model presents a 3D network of one-dimensional elements connecting particle's centres and comprising mutual interaction of particles. The contribution of the film layer and the interface thickness for normal stiffness is described analytically and illustrated by simulation results. Development of the normal interaction model of layered particles contacting via interface on the meso scale is the key point of the current development. The model applied aiming to simulate deformation of asphalt mixture is able to capture properties of the weaker matrix interface while layered particle comprises of bitumen film in meso scale. The developed technique is applied for simulation of Marshall test, i.e. diametric compression of cylindrical specimen, widely used for characterisation of asphalt mixtures. Finally, suitability of the model is illustrated by comparison with the available experimental results.
