I wonder if the modeling for composite rubberized concrete will be helpful to represent the numerical results that can be compared with the experimental one.

If the experimental results are the elastic properties the answer is :Yes!
If the strength is under concern a statistical-based approach is preferred.
There are many techniques helpful for modeling such cases, but I thought that ANN will be the best one if you have suitable data set. otherwise I can advise to use nonlinear regression modelling.Best regards

In case your question is about finite element modeling then Huang et al. (2004) proposed a modified three-layer built-in composite model to be used in finite element analysis of rubberized concrete. They mentioned that the interfacial bonding between the cement mortar and rubber chips plays a certain role in developing the strength of rubberized concrete and its reduced strength causes an inadequate interfacial bonding which can be simulated through a nodes merging process that allows the merged nodes at the interface to transfer load and the unmerged ones to model a partial interfacial debonding.
