TSS Removal Efficiency and Permeability Degradation of Sand Filters in Permeable Pavement
Round 1
Reviewer 1 Report
The paper "TSS Removal Efficiency and Permeability Degradation of Sand Filter in Permeable Pavement" presents a relevant theme, is within the scope of this journal, and can be considered after some corrections suggested below:
- The abstract section needs more improvements, as there are no results shown in this section.
- The intention of the study must be extended at the end of the introduction (not only the objectives). Why is this paper being written, and what is the difference between the present submitted paper and the previous works? What is needed for this paper? Explain all these questions at the end of the introduction part of the paper.
- The literature review needs more enhancements, and I would expect much more on the technical issues that reflect permeable pavement. For example, one valuable reference.
https://doi.org/10.1016/j.jmrt.2021.09.045
- In the methodology section, the authors may include a flow of the research process to clearly summarize the approaches involved.
- The authors need to give credit for the feasibility of supplementary materials like sand as filtration materials' application in solving diverse pavement concrete problems.
- I suggested to authors enhance the resolution the figures 5a and b. Which not clear and enlarge it?
- Finally, I believe the submitted paper can only be considered/accepted after correcting and/or adding the required points mentioned above for publication in the journal. I also believe that this paper might be beneficial for the academicians who are working in this specific area.

Reviewer 2 Report
Ms. Title: TSS Removal Efficiency and Permeability Degradation of Sand Filter in Permeable Pavement
This work is generally good, my main concern is the novelty, since the topic, used method, and research depth may not reach a level with enough scientific value.
1 Fig.3b, the text in this image is not clear enough for publishing.
2 Authors mentioned that ‘The TSS analysis was analyzed in accordance with the Quality Pollution Process Standard.’, please could you explain this method with more details.
3 The only pollutant was sand, it is acceptable, but in real world there should be contained others. However, in line 132 ‘Using silica sand with average diameters of 35 and 60 m’, I think the unit m was a typo. Furthermore, I suggest author to consider a wider diameter range of sand.
4 Can authors provide some actual pictures of the specimens? It would be clearer when the pictures are added.
5 Please recheck the regression equation in Fig.7, it seems not a linear regression, which often to be expressed as y=ax+b.
6 Beside the test results, I suggest authors to discuss more to explain why these results happened, how the clogging happens.

Reviewer 3 Report
The paper “TSS Removal..” has some merits but needs the following revisions:
Literature and intro. It is suggested to better deal with the literature where relationships are given between intrinsic properties (such as porosity) and the overall hydraulic performance (cf. 10.1080/14680629.2007.9690100). It is suggested to relate, at least from a conceptual standpoint, this fact to the gradation of the material.
QIC PDA: where did you explain this acronym?
Figure 4. An excellent figure but please make it easy to understand and highlight the type of material that flow.
TSS removal efficiency: where did you detail the meaning of this indicator?
Interaction between the upper layer (PICP) and lower layers: you may wish to describe the system and its parts and how the experiments you carried out on the part (?) can be useful to study/predict the behaviour of the system.
Kind regards

Round 2
Reviewer 1 Report
Generally, I am satisfied with the changes made by the authors, and I recommend that the manuscript be accepted in its current form.
Author Response
Dear reviewer,
Thank you for your time and your comments.
Sincerely.
Reviewer 2 Report
The article has been revised according to the comments and is fine to be accepted for publication.
One suggestion is as follows:
(1) Delete the data above the bar graph in Figure 11 and add a vertical axis scale.
Author Response
Dear reviewer,
Thank you for your comment, the data above the bar is the average TSS removal efficiency, which is already displayed in the vertical axis, and I already deleted it.
Sincerely.
