The application for the patent was published on October 23, 2026, under issue no. 43/2026.
Abstract: The present invention relates to a nanocenosphere-modified asphalt binder and a method of preparation thereof. The method comprises preheating a base asphalt binder (101), introducing nanocenospheres (102), and subjecting the resulting mixture to controlled high-shear mixing (109) to obtain a substantially homogeneous binder mixture (117). The prepared binder is evaluated through a softening point evaluation unit (120), and the blending parameters are iteratively optimized by an optimization decision module (140) and a blending parameter optimization module (132). Upon achieving predetermined thermal performance criteria, the binder undergoes rheological evaluation using a Dynamic Shear Rheometer (125), followed by cooling and stabilization (143) to produce a nanocenosphere-modified asphalt binder (145). The invention integrates thermal evaluation and rheological characterization into a performance-guided manufacturing methodology, thereby ensuring homogeneous nanocenosphere dispersion and producing an asphalt binder exhibiting improved thermal stability, enhanced rheological properties, superior rutting resistance, and extended service life suitable for flexible pavement applications.
