Super-viscous binder for low-noise super-overlay preventive maintenance capable of quickly opening traffic and preparation method of super-viscous binder for low-noise super-overlay preventive maintenance
The invention discloses a super-viscous binding material for low-noise super-overlay preventive maintenance capable of quickly opening traffic and a preparation method thereof. The super-viscous binding material comprises a reactive solvent, SBR (styrene butadiene rubber), SEBS (styrene-ethylene-butylene-styrene), matrix asphalt, a photocuring catalyst and photocuring acrylic resin, the preparation method comprises the following steps: heating the matrix asphalt, starting stirring, adding the reactive solvent, stirring for 25-30 minutes, sequentially heating the SEBS and the SBR, stirring for 4-6 hours, carrying out heat preservation development, adding the light-cured acrylic resin, stirring for 0.5-1.5 hours, finally adding the light-cured catalyst, and stirring for 20-30 minutes. The super overlay construction method is adopted, resin asphalt serves as a super-viscous asphalt binding material, the dynamic viscosity of evaporation residues at 60 DEG C is larger than 200,000 Pa * s, the viscosity is high, the binding capacity is good, the softening point of the evaporation residues is larger than 90 DEG C, the high-temperature performance is good, the ductility at 5 DEG C is larger than 30 cm, the low-temperature ductility is good, and the PG of the evaporation residues reaches 94-28.
本发明公开了一种可快速开放交通低噪超罩面预防性养护用的超粘结合料及制备方法，包括反应性溶剂、SBR、SEBS、基质沥青、光固化催化剂及光固化丙烯酸树脂；先将基质沥青加热后，开启搅拌，然后加入反应性溶剂搅拌25‑30min后，依次加热SEBS和SBR，搅拌4‑6h，保温发育后加入光固化丙烯酸树脂，搅拌0.5‑1.5h后，最后加入光固化催化剂在搅拌20‑30min，即可。本发明采用超罩面的施工方法，将树脂沥青为超粘沥青粘结材料，其蒸发残留物的60℃动力粘度＞20万Pa*s，粘度高，粘结能力好，蒸发残留物软化点＞90℃，高温性能好，5℃延度＞30cm，低温延度好，蒸发残留物的PG达到94‑28。
