Curing cold patch material suitable for low-temperature humid environment and preparation method thereof
The invention relates to a curing cold patch material suitable for a low-temperature humid environment and a preparation method of the curing cold patch material. The cold patch material comprises the following components in parts by weight: 64-78 parts of an RAP material, 16-31 parts of a novel aggregate, 0.9-1.1 parts of a regenerant and 3-5 parts of cold patch asphalt. Wherein the cold patch asphalt comprises the following components in parts by weight: 45-56 parts of modified asphalt, 28 parts of liquid soap and 20-26 parts of low-temperature curing epoxy glue (latent epoxy resin). The preparation method comprises the following steps: slowly adding the regenerant into the preheated RAP material at a constant speed, uniformly mixing the components, adding the cold patch asphalt and the preheated new aggregate, uniformly mixing the components, and discharging the mixture when the temperature is less than or equal to 80 DEG C. Compared with the prior art, the cold patch material disclosed by the invention has the advantage of being rapidly combined with a damaged pavement in a low-temperature humid environment, and has a wide prospect when being applied to the fields of road maintenance and emergency maintenance.
本发明涉及一种适用于低温潮湿环境的固化冷补料及其制备方法，所述用冷补料包括如下重量份的组分：RAP料64‑78份、新集料16‑31份、再生剂0.9‑1.1份以及冷补沥青3‑5份。其中冷补沥青按重量份计包含以下组分：改性沥青45‑56份，皂液28份，低温固化环氧胶(潜伏性环氧树脂)20‑26份。制备方法是：将再生剂缓慢匀速加入预热后的RAP料中，拌和均匀后，加入冷补沥青、预热的新集料，拌和均匀，待温度≤80℃时出料。与现有技术相比，本发明所述冷补料具有在低温潮湿环境下与破损路面快速结合的优势，应用于道路养护、应急维修领域的前景广阔。
