I am intending to work on a simulation software in pavement engineering. I am interested to simulate asphalt behavior using the simulation software. Which behavior of asphalt should I start with? For Example, crack propagation simulation, microstructural simulation (I saw a paper). Can you also suggest a suitable software. Regards,
Imtiaz Ahmed
Thank you so much Behrooz Saghafi for your answer. I shall be studying further literature to narrow the line for my work. As you are also interested in simulation, I shall be in contact with you to share my experiences and guidance from your side.

Many studies suggested that Discrete Element Method (DEM) via PFC2D and PFC3D software (Itasca) could be used to to simulate deformation and fracture in different materials, even in asphalt mixes. The discrete element algorithm models a continuum as a system of distinct, interacting, and general-shaped particles subjected to laws of motion and deformation, which are bonded together. When the maximum stress in a contact bond is reached, the bond is broken and a separation of these particles (cracks) can be observed.
PFC software is a little tricky and not that user friendly, especially if you are going to use your own model to simulate asphalt mixes responses.
Good luck.
Dear Dr. Abdo,
I shall try to follow your suggestions. Currently, I am a little busy and not able to work on the said project. I shall be in touch while trying to simulate the behavior of asphalt using different statistical packages.

I think you must first check the constitutive relationship adopted in each software at beginning.
