Research on Pavement Performance of Cement-Stabilized Municipal Solid Waste Incineration Bottom Ash Base
Round 1
Reviewer 1 Report
This article focuses on the Pavement performance of cement-stabilized municipal solid waste incineration bottom ash base. This manuscript is well organized. However, some minor issues need to be addressed before publication.
Abstract: Authors can condense the abstract and include major outcomes of the study
1. Recast line 11 and make it clearer.
2. Line 14 should read " 7 days unconfined …..”.
Line 29 should read “carbon peaking, and ……..”
3. Line 76, Please add a good justification of the work and indicate the novelty of the work. This is very important.
4. Line 81, Table, always indicates the day(s) instead of d
5. Line 93, Table 3, should read “apparent density (g/cm3)”.
6. Line 122, how can you define the plasticity behavior of bottom ash, which is having liquid limit 42.8 (intermediate compressibility)
7. Line 157, how can you define the slenderness ratio of the sample, and what about the maximum size of the particle in the blend?
8. Line 281-285, Need a scientific explanation. Based on the reviewer's knowledge, bottom ash is a lightweight material and has higher compressible nature. How can it develop dense phase and frictional resistance in the blend?
9. Line 291, should read “first-grade”
10. Line 314, Need better explanation. The compressive strength still increases greatly at the late curing stage with bottom ash.
11. Sections 3 and 4, the discussion of this work is needed to be improved. The authors need to rewrite the results and discussion section. Most results were only stated without comparing with other studies around the world. Authors need to compare the results of each parameter with similar studies around the world and also give reasons for differences between compared studies. The authors also need to reflect on the variations in the stress strains with the MSW bottom ash chemical composition.
12. Authors need to provide reasons for the increased levels of MSW bottom ash, even though there is a loss in the blend's performance.
13. Line-516, Avoid the usage of I or We in the whole manuscript
14. Section 6, more references will strengthen the discussion. Cite related studies and compare the sustainable utilization of MSW bottom ash in the pavements.
15. The conclusion should be rewritten and made briefer to show the major findings of the study and conclusions drawn.
16. Avoid references older than 5 yrs (>2017)
17. Finally, I suggest the authors thoroughly check the manuscript for spelling mistakes and correct it with a native speaker fluent in technical English to improve the language and its quality.
