Title:
ULTRA-ELASTIC RUBBER ASPHALT USING THE POLYMERIZATION METHOD AND SYMMETRY TECHNIQUE
Document Type and Number:
WIPO Patent Application WO/2023/084504
Kind Code:
A1
Abstract:
The claimed invention is " Ultra-Elastic Rubber Asphalt by Polymerization Method and the Symmetry Technique " with the aim to improve the mechanical and rheological properties of bitumen and asphalt to prevent susceptibility to damage and the occurrence of accidents for users, including cyclists. mixing rubber powder with bitumen is done by employing the "wet process". Next, favorable conditions for creating chemical bonds (transverse sulfur bond in the chain Di-en rubber)are created by mixing special bitumen with polymerization capability and fine-grained stone materials and adding rubber granules to the asphalt mixture mentioned above (dry process) in the presence of sulfur and ZnO at a 160 °C temperature. Mixing these compounds, and the simultaneous mixing of rubber powder and rubber granules with bitumen and asphalt (the symmetry technique) provide the conditions required for producing asphalt with high elasticity.
