This manuscript introduces a prefabrication-oriented Bridge Deck Asphalt Pavement (BDAP) system, accompanied by a finite element model analyzing the mechanical behavior of its joint regions. The research aligns with contemporary interests in sustainable, rapid, and intelligent construction methodologies. The following specific comments and suggestions are provided to assist the authors in improving the manuscript:

 1. Figures 1(a) and 2 appear to convey overlapping information regarding the BDAP structure. To avoid redundancy and improve clarity, consider combining these into one figure that effectively illustrates the difference between ordinary asphalt pavement structures and also the structure of joint connections. 

2. In Conclusion 2, the manuscript states that "the existence of joints leads to an increase in the maximum tensile stress in the upper layer and a decrease in the maximum tensile stress in the lower layer, which is unfavorable for the mechanical state of BDAP." Are there any references to relevant literature or analysis from the author’s study to support this conclusion? 

3. The current Conclusions section includes detailed descriptions of Figures 4 and 5, which may be more appropriately placed within the results and discussion, which is next to these figures. 

4. Some statements in the Conclusions, such as "the maximum tensile stress of the top layer of asphalt paving is always significantly smaller than that of the top layer in conclusion 2," reiterate observations that are evident from the figures. Consider removing such redundant statements to maintain a concise and impactful conclusions section. 

5. In Conclusion 4, the manuscript suggests that "materials with consistent material properties" were used, based on Figure 5 indicating similar modulus magnitudes. However, modulus similarity does not necessarily equate to identical material properties. It would be beneficial to revise this statement.
