Thanks you for your question,,

Yes my documentation about pavement about disorders after long submersion,,

Possible solution is increase peformance with additif such as natural zeolite

Hi Anas

Usually concrete pavements are designed for flooding areas. Stabilised pavement (using cement or form-bitumen to granular) is another option. During flooding voids will be filled with water & strength of granular pavement will be decreased as a result. Please see the attached.

Here are some impacts of long term flooding pertinent to structural distresses:

1. Reduction in structural strength

2. Increased deflections

3. Loss of sub-grade strength

4. Increase in roughness, rutting, and fatigue cracking

5. Potholes

6. Swelling

7. Joint deterioration

The underlying layers play a critical role. If fundamental drainage is an issue, then it would be convenient to either provide dense surface and drainage layers or a proper drainage system. Another solution could be the provision of gap-graded asphalt or porous asphalt / concrete in top surface course, followed by a concrete base course, and subsequent dense layers. Furthermore, utilize additive materials that reduce the pavement's susceptibility to moisture.

Attached are a few studies for your reference:
