Water reaction type asphalt cold patch material and preparation method thereof
The invention relates to a water reaction type asphalt cold patch material and a preparation method thereof. The water reaction type asphalt cold patch material comprises the following components in parts by mass: 1000 parts of aggregate; 50 to 60 parts of mineral powder; the evaporation residue content of the emulsified asphalt is not less than 60.5%, the elastic recovery at 25 DEG C is not less than 93%, the composite shear modulus at 60 DEG C is not less than 10 kPa, and the dynamic viscosity at 60 DEG C is not less than 38500 Pa.s; 15 to 30 parts of a demulsifier; 1 to 10 parts of super absorbent resin; the epoxy resin is 20-40 parts, and the ratio of the curing agent to the epoxy resin is 1: 0.5-1: 2; and 5-15 parts of a self-heating component, an environment-friendly solvent and a modifier. The cold patch material is faster in curing and stronger in adhesive property. According to the water reaction type asphalt cold patch material, the characteristics of self-heating and rapid reaction are utilized, and a rapid and efficient road repairing scheme is provided under the severe weather condition. Particularly, the self-heating component and the super absorbent resin are added to adapt to low-temperature and humid conditions, so that the curing is quicker, and the adhesive property is stronger.
本申请涉及一种水反应型沥青冷补料和制备方法，该水反应型沥青冷补料的质量份组分有集料1000份；矿粉50份至60份；乳化沥青85份至150份，所述乳化沥青的蒸发残留物含量不低于60.5％，25℃弹性恢复≥93％、60℃复合剪切模量≥10kPa、60℃动力粘度≥38500Pa·s；破乳剂15份至30份；高吸水树脂1份至10份；所述环氧树脂20份至40份，所述固化剂与所述环氧树脂的配比为1:0.5至1:2；自加热组分，环保溶剂和改性剂5份至15份。该冷补料固化更迅速、粘结性能更强。这种水反应型沥青冷补料利用自加热和快速反应的特性，在恶劣的气候条件下提供了一种快速、高效的道路修补方案。尤其是通过添加自加热组分和高吸水树脂以适应低温和潮湿条件，使其固化更迅速、粘结性能更强。
