Rheological Properties and Performance Evaluation of Different Types of Composite-Modified Asphalt in Cold Regions
Round 1
Reviewer 1 Report
Comments and Suggestions for AuthorsThe article must be improved:
The goals are not clear of your research article, please clarify them
The abstract is not clear: "Composite modification is carried out for 70#, 90# and 110# matrix asphalt" please clarify this point
On the other hand explain the most rellevant conclusions, introduce a Table in the article in order to summarize the most important variables and compare them,
finally obtain conclusions of application from your research to cite which would be the best asphalt compounds analyzed for application

Reviewer 2 Report
Comments and Suggestions for AuthorsA comparative study of the differences in physical properties of modifiers on the performance of modified asphalt:
The title does not align with the contents of the paper "The Physical Properties," which focuses on evaluating physical properties using DSR, BBR, and SEM.
Abstract: It's more effective to present results in numerical form, such as "we can improve the high temperature or low temperature; add the percentage of improvement."
Please define the terms 70#, 90#, and 110# matrix asphalt in the abstract section.
lines 125-126: The asphalt used in this experimental study is Shandong Jinshi 70# base asphalt.
Liaoning Panjin 90# base asphalt, and Liaoning Panjin 110# base asphalt. The technical indicators of each base asphalt are shown in Table 1 below. Please revise the text to include the use of three distinct types of asphalt as the base asphalt binder.
Lines 167-168: Indicate the page 5 retrieval.
lines169-171: This article is mainly aimed at asphalt pavement materials in cold areas. Therefore, compared with high-temperature performance, the low-temperature performance and water stability of pavement materials are the main directions of this study. This section lacks any relevant information. Please remove it.
Line 177 represents the Modifier Combination Scheme. In the asphalt section, the base asphalt was given as numbers, but it appears that SBS has modified the base asphalt. To be honest, this section is useless; it would be better to remove it.
Line 179: The shearing time (t) and rate (v)—how the authors have chosen such parameters.
Line 198: Table 8. The optimal dosage of the modifier
The text in its current form is quite difficult to understand; please review it.
lines 273-275: Testing Procedures for Asphalt and Asphalt Mixtures in Highway Engineering: For which country?
line 341: Figure 8. Energy change diagram for different types of modified asphalt. Where are the other modifiers? Why do you only focus on two?
Line 356: Please change it to "as shown in Figures 9-11."

Reviewer 3 Report
Comments and Suggestions for AuthorsThe work reported by Hu et al is very interesting in the modification of asphalt materials enabling them to be resistant to cold climate conditions. I believe this work is suitable for publication in Coatings, MDPI after addressing the following comments:
(1) A clear paragraph in the Introduction section should be added to explain the novelty and originality of this work.
(2) Lines 85-86: The following citation is required: https://doi.org/10.1080/10916466.2021.2017457
(3) Figure 2. Saturates not saturation. Have the authors performed SARA analysis for their asphalt samples ?
(4) Why didn't the author perform ICP analysis for their asphalt samples ?
(5) Conclusions need to be rewritten in a more concise and clear manner.
