I currently concluding my MSc in Concrete durability and would like to pursue a research interest in rigid–flexible composite pavement, I have limited advance information on these topics;
Durability problems of asphaltic concrete
Durability problem of rigid-flexible pavement
flexible and rigid pavement durability.
Also I would like list of test/equipment methods associated with each problem (accelerated and natural test)
The major issue is not one found in the lab. It is the delamination of the composite layers in the field where the consistency of the bonding compound is much harder to control.
Do you mean flexible on joined or flexible on CRC? Also, what do you mean by 'durability'? We have excellent performance on flexible over CRC (old in service). SHRP2 has a two volume report on composite pavement reporting very good performance as well. The report can be found from the following link.

@Affan Habib, I meant flexible both, issues point out by Douglas on delamination of layers.
