Reviewer 1:

1. The reason for using 0%, 5.7%, and 25.6% lime is not clear.

2. Section 3.2 heading- check the spelling of "Relaxation"

3. Is there any evidence of HL acting as an active filler in this study? What new information is provided through the results?- This is not evident.

Reviewer 2:

Overall, this manuscript addresses an important topic—the use of hydrated lime (HL) to improve the durability of porous asphalt mastics and mixtures—through a comprehensive suite of rheological, chemical, and mechanical tests. The experimental design encompasses fresh, aged, and pre-aged binders, and the F-test statistical analysis is well-intentioned. The results are presented clearly and the conclusions generally follow from the data. Below are several constructive suggestions to further strengthen the clarity, reproducibility, and statistical rigor of the paper.

1. Embedding “[11]” as the direct object in “The PA 16 mixture was aged using the aging protocol described in [11].” can interrupt reading flow

2. The paper omits the PA 16 mixture’s gradation curve, binder content, and target air-void percentage

3. DSR test temperatures and the frequency sweep range used to build the master curves are not specified

4. The method for determining the WLF shift factors (e.g., fitted C₁/C₂ values vs. manual alignment) is not described

5. Figure 1 does not annotate the 0 °C reference temperature on the plot nor employ a secondary axis for |G*| (MPa) vs. δ (°)

6. The FT-IR section lacks a clear identification of which stable reference peak was used to normalize the carbonyl and sulfoxide bands in Figure 3

7. The number of replicates for DSR, FT-IR, and ITS tests—which determines ANOVA’s degrees of freedom—is not reported

8. No ANOVA or post-hoc significance tests (e.g., Tukey HSD) are provided to confirm whether observed ITSR differences between fillers are statistically significant

9. Standardize terminology: use either “pre-aged binder” or “aged binder prior to mixing” consistently (i.e., a*Mi).

10. Spell-check “pahse angle” → “phase angle,”“separtely” → “separately,” and “calcualting” →“calculating.”

11. In tables and captions, ensure consistent formatting of subscripts and superscripts (e.g., 1×10⁻⁵ Hz).
