AI Technical Summary
Existing technologies face challenges in incorporating cellulose fibers into bituminous materials due to property dissimilarities, leading to heterogeneities and segregation, which are exacerbated by high temperatures and on-site mixing difficulties, necessitating rapid and homogeneous mixture preparation.
A stabilizing product comprising cellulose fibers and bitumen in specific proportions, with mineral fillers and optional additives, allows for quick and easy integration into bituminous mixes, ensuring homogeneity and avoiding segregation, with a pH of 7.5 +/- 1 and moisture content below 7%, facilitating on-site composition adjustments.
Enables rapid, homogeneous mixing of cellulose fibers with bituminous materials, reducing fiber breakage and ensuring better dispersion, allowing real-time composition adjustments and improved quality of stabilized bituminous coatings.
