AI Technical Summary
Existing thin-layer overlay asphalt mixtures are prone to rapid temperature loss and are difficult to compact during paving, resulting in significant quality issues and substantial scattering losses, making it difficult to meet the requirements for thin-layer overlay construction.
The process involves mixing styrene-butadiene-styrene, styrene-isoprene-styrene, white oil, epoxidized soybean oil, furfural extract, glycerol monofatty acid esters, and antioxidants with molten matrix asphalt. This mixture is then sheared and developed to form the first mixture, which is then mixed with basalt and mineral filler to reduce paving temperature and control scattering losses.
It enables easy compaction at lower paving temperatures, improves the construction quality of thin overlays, and reduces Kentenberg scattering losses, making it suitable for thin-layer asphalt mixtures.
