Title:    Predicting Flexible Pavement Distress and IRI considering Subgrade Resilient Modulus of Fine-Grained Soils using MEPDG

Materials

The paper presents an interesting paper related to subgrade resilient modulus of fine-grained soils. The following notes were outlined:

1.        Page 1 – line 42: It is preferred to mention the methods used to measure the flexible pavement distress.

2.        Page 2 – line 50: The following studies may be beneficial. You can also refer to them:

3.     Figure 2 is not clear.

4.     What are the climate inputs used in the analysis ?

5.     In Table 2, mention the test from which each property was determined.

The specific gravity 2.51 is small.

6.     In Figure 5, choosing age of 20 years for pavement is too long.

Reviewer 3 Report

It has certain scientific value

The research  is of limited value

The innovation of the paper is not too high.

This kind of research is very common.

However, it can be considered for publication after revision.
