Clarity of writing. The English language should be improved. The manuscript has grammatical mistakes and awkward phrases throughout the manuscript, especially in the "Results and Discussion" section, which may hinder understanding.
References. There are references to sources [1-3] in the second paragraph of the "Introduction" (p.1 of the manuscript), but only one reference is provided. It is recommended to expand the bibliography with relevant and up-to-date sources (especially from the last 5 years) concerning bitumen modification, cold-applied roofing materials, and SBS-based composites.
Scientific novelty. While the work is practically valuable, the authors should emphasize the scientific novelty more clearly. For example, explain in greater depth why rapeseed oil is a better choice than linseed oil, beyond the cost factor.
Tables. The tables contain a large amount of data. It would be helpful to summarize key trends or observations briefly after each table to support reader comprehension.
Conclusions. The conclusions are generally well-structured and supported by the data. However, they could be enhanced by briefly outlining potential directions for future research — such as evaluating the long-term performance of the developed material or addressing industrial scale-up possibilities.
