Round 1
Reviewer 1 Report
To me:
Tables 1 till 5 need add references.
Figs 1 and 2 need more clear.

Reviewer 2 Report
The paper introduces a new high-permeability emulsified asphalt and its modification by 20% water-based epoxy resin. The new emulsified asphalt is innovative and practical. The paper has good experiences design, but more discussion and analysis should be added. The blew comments from reviewer might help to improve.
1, language, grammar, some vocabularies usage, and form should be improved, for example the word “diseases” is just used for living, “distress” is used for pavement; there is a sentence in 1st paragraph of page 3 containing 6 lines, it is very difficult to follow.
2, the discussion in depth of the references and effect on your research should be added into the introduction, not just a simple description. The significance of your work also is added into the abstract and introduction.
3, in section 3.2, the formula 2 was selected as the best one. More reasons and evidence should be used to demonstrate why the outcome, from material composition, discuss and analyze effect of the different materials on diffusion.
4. in section 3.3.1, why does high-permeability emulsified asphalt have better storage stability? The authors should illustrate.
5, Conclusion is too long, should be more refined.
In general, the paper is more like a experiments report, lacking more and deeper discussion and analysis than a research paper

Reviewer 3 Report
This research developed and modified a novel high-permeability emulsified asphalt with high stability and bonding performance. The study has new contributions to sciences; however, it needs extensive English editing and also some technical errors need to be corrected
- Pls revise the abstract; it should contain the objective very clearly and the modified emulsified asphalt's formula should be stated.
- Pls strengthen the Introduction; several sentences were repeated and some of them are very general. Authors are suggested to cite more recent relevant studies.
-Materials section should be modified; section 2.1.1. need to put after the materials used in this study as this section is for sample preparation. In addition, for Cationic emulsifiers, Diluent, and Stabilizer should be put in sample process and try to not include all these general information.
-For Limestone, it is stated that the limestone in a coarse aggregate. How about the fine aggregate; what type of aggregate used.
-Table 6 shows the Gradation of asphalt concrete; Pls show what are the optimum bitumen content and volumetric properties.
- In Preparation Process, why the 60 C temperature was chosen!
-filter paper was tested, every 1, 3, 4, 5, 6, 24, 48, and 72 hours. Can authors elaborate more why these periods were selected? also for FM test, why intervals of 1, 7, 14, and 28 days were chosen?
-Pg 10, pls explain more why the 3 min was selected in sentence "when the seepage rate is very slow, only the amount of water seepage in 3 minutes should be recorded" also, pls cite the standards used for this test.
-Table 8, authors are required to explain more how these proportions were specified?
-Pg 11, "Five kinds of emulsified asphalt on filter paper of 300,400,500, every 1,3,4,5,6,24,48,472 hours" what authors mean by values of 300,400,500? write the unit and use "and" before number (before 500 and before 472). the number of 472 is correct! or 72 hrs.
-Pg 14, sentence "In order to observe the dispersion state of asphalt components and the aggregation process of asphalt in high permeability emulsion asphalt and emulsified asphalt" doesnt make any sense; pls revise it.
-Pls add more in depth discussions for all findings.
- some errors were detected, Pls proofread the text.
-change the word "disease" in the introduction with "distress"
-Pls either use Fig. or Figure in the text; Pg 10 change "FIG. 10" to figure 10 as the phrase of "Figure" was used earlier in the text.
-Pls use high-quality graphs for Figs. 1,2,5. 11, 12, 15, and 16.
-use full-stop for all table titles.
-For pull-off test, what is the value of applied load.
- revise all section titles as some were written with upper case and other lower-case.
-Pg 14, revise this sentence "As can be seen from Table 4 and Figure 3" you may add "it" before "can".
-Pls avoid using long sentences such as :
1. Pg 16 " As can be seen from Table 5, the tensile........emulsified asphalt should be improved."
2. Pg 17 "As can be seen from Table 11, the tensile strength.........that of the emulsified asphalt." the sentence "The modified scheme is effective." doesnt sound good.
3. Pg. 1 "To improve the continuity ............ structure more entirely and continuously."
- Pls use full stop before (Wu and Li [16] (Pg. 2)) and (The depth of penetration increases).
